Als Umgebung zur Programmierung des Roboters wird code-server eingesetzt, welche bereits am Roboter vorinstalliert ist.

+
+

Verbindung zur Entwicklungsumgebung herstellen

+

Am Roboter wird die IP-Adresse des Raspberry Pi angezeigt. Um nun die Verbindung herzustellen, muss man in einem Web-Browser einfach <roboter_ip>:8080 eingeben. +Das Passwort für Visual Studio Code im Browser ist compair!

Mein erstes Programm

+

Um mit der Programmierung zu beginnen, müssen wir zunächst einen neuen Ordner erstellen, in dem alle unsere Python-Dateien gespeichert werden. +codeServerFolder

+

Sie können diesen Ordner nennen, wie Sie wollen, für dieses Beispiel heißt er compAIR. +Im nächsten Schritt erstellen wir unsere Datei main.py. +codeServerFile

+

Dann können wir beginnen, unseren Code in diese Datei zu schreiben.

+
print("Hallo Welt")
+
+
+

Praktischerweise können wir die Datei auch über die VS-Code-Plattform ausführen. +codeServerRun

+

Dann öffnet sich ein Terminal, der die Ausgabe unseres Programms anzeigt. +codeServerTerminal

Mein zweites Programm

+
+

Motoren ansteuern

+

Um die Motoren des Roboters zu steuern, müssen wir zunächst das entsprechende Python-Modul am Anfang der Datei importieren. Dann können wir Motor.power(port, power) verwenden, um den Motor zu steuern. +Dies ist auch ein guter Punkt, um sich mit der Dokumentation vertraut zu machen: Besuchen wir https://lib.comp-air.at/lib/Motor.html#compLib.Motor.Motor.power. Hier werden die beiden relevanten Parameter beschrieben.

+

Als Beispiel wollen wir den rechten Motor für fünf Sekunden auf volle Geschwindigkeit setzen:

+
1
+2
+3
+4
+5
+6
# motor.py
+import time
+from compLib.Motor import Motor
+
+Motor.power(0, 100)
+time.sleep(5)
+
+
+
+
+

Gerade fahren

+

Um geradeaus zu fahren, müssen wir beide Motoren auf dieselbe Geschwindigkeit einstellen. +Aber Achtung! Der rechte Motor muss umgedreht werden! Das liegt daran, dass einer nach rechts und einer nach links zeigt, sie sind also technisch gesehen gespiegelt. +Wenn wir nun diesen Code ausführen, wird der Roboter 5 Sekunden lang vorwärts fahren:

+
1
+2
+3
+4
+5
+6
+7
# motor.py
+import time
+from compLib.Motor import Motor
+
+Motor.power(0, -100)
+Motor.power(3, 100)
+time.sleep(5)
+
+
+

Erläuterung

+
+
In Zeile 2 wird das python-Paket time importiert. Wir brauchen es später, um auf die Fahrt des Roboters zu warten. Z.B.: time.sleep(5)
+
In Zeile 3 importieren wir die notwendigen Funktionen aus dem Motor-Modul der compLib.
+
In Zeile 5 stellen wir den rechten Motor so ein, dass er vorwärts fährt. Da der Motor rückwärts eingebaut ist, müssen wir den Wert auf -100 setzen.
+
In Zeile 6 stellen wir den linken Motor auf Vorwärtsfahrt ein. Hier können wir den Wert 100 verwenden, da der Motor in der richtigen Richtung eingebaut ist.
+
In Zeile 7 müssen wir warten, bis der Roboter die Fahrbefehle tatsächlich ausführt. In diesem Fall warten wir 5 Sekunden lang.
+
+

Danach wird das Programm beendet und der Roboter bleibt stehen.

+
+

Mehr fahren

+

Jetzt ist es Zeit für einige komplexere Bewegungen. Um unseren Code modular und leicht lesbar zu halten, werden wir jede Aktion in eine eigene Funktion packen.

+
1
+2
+3
+4
+5
+6
+7
import time
+from compLib.Motor import Motor
+
+def driveForward():
+    Motor.power(0, -100)
+    Motor.power(3, 100)
+    time.sleep(2)
+
+
+

In Zeile 4 definieren wir die Funktion driveForward(), die den Roboter mit voller Geschwindigkeit zwei Sekunden vorwärts bewegt.

+

Jetzt werden wir eine Funktion für das Rückwärtsfahren definieren:

+
 1
+ 2
+ 3
+ 4
+ 5
+ 6
+ 7
+ 8
+ 9
+10
+11
+12
import time
+from compLib.Motor import Motor
+
+def driveForward():
+    Motor.power(0, -100)
+    Motor.power(3, 100)
+    time.sleep(2)
+
+def driveBackward():
+    Motor.power(0, 100)
+    Motor.power(3, -100)
+    time.sleep(2)
+
+
+

In Zeile 9 haben wir die Funktion driveBackward() definiert, die den Roboter zwei Sekunden lang rückwärts fahren lässt.

+

Jetzt können wir diese beiden Funktionen aufrufen und vorwärts und dann wieder rückwärts fahren:

+
 1
+ 2
+ 3
+ 4
+ 5
+ 6
+ 7
+ 8
+ 9
+10
+11
+12
+13
+14
+15
import time
+from compLib.Motor import Motor
+
+def driveForward():
+    Motor.power(0, -100)
+    Motor.power(3, 100)
+    time.sleep(2)
+
+def driveBackward():
+    Motor.power(0, 100)
+    Motor.power(3, -100)
+    time.sleep(2)
+
+driveForward()
+driveBackward()
+
+
+

Wenn wir diesen Code ausführen, sollte der Roboter zunächst zwei Sekunden vorwärts und dann wieder zwei Sekunden rückwärts fahren und ungefähr an der gleichen Position wie beim Start anhalten.

+

Zwischen den Zeilen 14 und 15 brauchen wir kein time.sleep(2), da der sleep-Befehl bereits in den Funktionen integriert ist.

+

Jetzt wollen wir, dass der Roboter erst vorwärts fährt, dann zwei Sekunden stillsteht und dann wieder rückwärts in seine Ausgangsposition fährt.

+
 1
+ 2
+ 3
+ 4
+ 5
+ 6
+ 7
+ 8
+ 9
+10
+11
+12
+13
+14

import time
+from compLib.Motor import Motor
+
+def driveForward():
+    Motor.power(0, -100)
+    Motor.power(3, 100)
+    time.sleep(2)
+
+def driveBackward():
+    Motor.power(0, 100)
+    Motor.power(3, -100)
+    time.sleep(2)
+
+driveForward()
+time.sleep(2)
+driveBackward()
+
+
+

Wenn wir den obigen Code ausführen, bleibt der Roboter nicht zwei Sekunden lang stehen, sondern fährt nach der Funktion driveForward() noch zwei Sekunden lang weiter. Warum passiert das? Um das zu verstehen, müssen wir wie der Roboter denken!

+

Erläuterung

+
+
1. (Zeile 14) Die Funktion Vorwärtsfahrt wird aufgerufen
+
+
(Zeile 5) Motor 1 wird auf -100 gesetzt
+
(Zeile 6) Motor 4 wird auf 100 gesetzt
+
(Zeile 7) Zwei Sekunden warten und Motor 1 mit der Geschwindigkeit -100 und Motor 4 mit der Geschwindigkeit 100 bewegen (z.B. vorwärts fahren)
+
+
+
+
2. (Zeile 15) Zwei Sekunden warten, die Motoren sind immer noch auf -100 und 100 eingestellt, also fahren wir weiter vorwärts
+
+
+
3. (Zeile 16) Die Funktion Rückwärtsfahren wird aufgerufen
+
+
(Zeile 5) Motor 1 wird auf 100 gesetzt
+
(Zeile 6) Motor 4 wird auf -100 gesetzt
+
(Zeile 7) Warte zwei Sekunden und bewege Motor 1 mit der Geschwindigkeit 100 und Motor 4 mit der Geschwindigkeit -100 (z.B. Rückwärtsfahren)
+
+
+
+
4. Das Programm ist beendet, und alle Motordrehzahlen werden auf 0 gesetzt.
+
+

Wir sehen also, dass wir die Motoren nach der Vorwärts- oder Rückwärtsfunktion wieder auf Geschwindigkeit 0 setzen müssen, wenn wir den Roboter anhalten wollen. Für diesen Anwendungsfall können wir eine neue Funktion stopMotors() schreiben, die die Geschwindigkeit für Motor 0 und 3 auf 0 setzt:

Wenn wir nun vorwärts fahren, dann zwei Sekunden warten und dann wieder rückwärts fahren wollen, können wir die Funktionen wie folgt aufrufen:

+
 1
+ 2
+ 3
+ 4
+ 5
+ 6
+ 7
+ 8

+    time.sleep(2)
+
+def driveBackward():
+    Motor.power(0, 100)
+    Motor.power(3, -100)
+    time.sleep(2)
+
+def stopMotors():
+    Motor.power(0, 0)
+    Motor.power(3, 0)
+
+driveForward()
+stopMotors()
+time.sleep(2)
+driveBackward()
+
+
+

Und endlich bekommen wir die Bewegung, die wir uns wünschen.

+

More Optimizations

+

Während der Code für sehr einfache Bewegungen funktioniert, wollen wir normalerweise nicht, dass unsere Funktionen entscheiden, wie lange wir vorwärts fahren. Vielleicht müssen wir manchmal vier Sekunden vorwärts fahren, und manchmal nur eine Sekunde.

+

Nehmen wir an, wir wollen vier Sekunden vorwärts fahren. Wir wissen, dass driveForward() den Roboter zwei Sekunden vorwärts bewegen wird. Also können wir die Funktion einfach zwei Mal aufrufen!

+

import time
+from compLib.Motor import Motor
+

+    Motor.power(0, -100)
+    Motor.power(3, 100)
+    time.sleep(2)
+
+driveForward()
+driveForward()
+
+
+

Was aber, wenn wir uns nur eine Sekunde vorwärts bewegen wollen? Oder vielleicht drei Sekunden? Mit der Funktion driveForward() können wir das im Moment nicht machen.

+

Stattdessen werden wir die Funktion so umschreiben, dass sie einen Parameter akzeptiert, der die Zeit angibt.

+

+4
+5

import time
+from compLib.Motor import Motor
+
+def driveForward(seconds):
+    Motor.power(0, -100)
+    Motor.power(3, 100)
+    time.sleep(seconds)
+
+driveForward(3)
+
+
+

Und mit dieser neuen Funktion können wir drei Sekunden lang vorwärts fahren. +Wie funktioniert das nun?

+

In Zeile 4 definieren wir die Funktion driveForward und sagen, dass sie einen Parameter seconds benötigt. Dieser Parameter ist im Grunde eine Variable, die wir uns zum Zeitpunkt der Definition wie einen Platzhalter vorstellen können. Wenn wir die Funktion definieren, wissen wir noch nicht, welchen Wert seconds haben wird.

+

Später in Zeile 9, wenn wir die Funktion aufrufen, übergeben wir den Wert 3 an die Funktion und unser Platzhalter seconds wird den Wert 3 haben. Der Roboter wird also drei Sekunden vorwärts fahren.

+

Vielleicht wollen wir auch, dass der Roboter mit verschiedenen Geschwindigkeiten fahren kann. Wir können also einen weiteren Parameter mit dem Namen speed anlegen. Dann werden wir ein Programm schreiben, das den Roboter drei Sekunden mit voller Geschwindigkeit und dann fünf Sekunden mit halber Geschwindigkeit fahren lässt.

+

import time

+    Motor.power(0, -speed)
+    Motor.power(3, speed)
+    time.sleep(seconds)
+
+driveForward(3, 100)
+driveForward(5, 50)
+
+
+

In Zeile 9 wird der Platzhalter seconds auf 3 und die Geschwindigkeit auf 100 gesetzt. +In Zeile 10 wird der Platzhalter seconds auf 5 und die Geschwindigkeit auf 50 gesetzt.

+

Bewährte Praktiken +Nun werden wir uns einige weitere Optimierungen und bewährte Verfahren ansehen.

+

1. Wir sollten den Schlafbefehl nicht in die Fahrfunktion einbauen.

+

Wir haben das bis jetzt getan, um ein Gefühl dafür zu bekommen, wie Funktionen funktionieren, und der Einfachheit halber. Später, wenn Sie anfangen, komplexere Programme zu schreiben, sollten Sie dies vermeiden.

+

Das Beispiel von oben, in dem wir vorwärts und rückwärts gefahren sind und zwei Sekunden gewartet haben, sollte also wie folgt aussehen:

+

+ 4
+ 5
+ 6
+ 7

import time
+from compLib.Motor import Motor
+
+def driveForward(speed):
+    Motor.power(0, -speed)
+    Motor.power(3, speed)
+
+def driveBackward(speed):
+    Motor.power(0, speed)
+    Motor.power(3, -speed)
+
+def stopMotors():
+    Motor.power(0, 0)
+    Motor.power(3, 0)
+
+driveForward(100)   # Set the motors to forward
+time.sleep(2)       # Let the robot drive for 2 seconds
+stopMotors()        # Now stop the robot
+
+time.sleep(2)       # Wait another 2 seconds, robot is not moving
+
+driveBackward(100)  # Now set the motors to a backwards speed
+time.sleep(2)       # Let the robot continue driving for 2 seconds
+stopMotors()        # And finally stop it again
+
+
+

Warum ist das so wichtig?

+

Normalerweise schlafen wir nicht sehr viel und führen in dieser Zeit andere Verarbeitungen durch. Zum Beispiel könnten wir ein Bild von der Kamera verarbeiten oder die IR-Sensoren auslesen. Wenn wir also eine Funktion wie driveForward() aufrufen, können wir davon ausgehen, dass sie im Hintergrund abläuft und wir andere Aufgaben erledigen, während sich der Roboter bewegt, anstatt nur darauf zu warten, dass er fertig wird.

+

2. Fahren Sie nicht zu langsam.

+

Wenn du die Fahrgeschwindigkeit auf eine sehr kleine Zahl einstellst, kann es sein, dass sich der Roboter gar nicht mehr bewegt, weil die Motoren eine bestimmte Menge an Energie benötigen, um den Roboter überhaupt zu bewegen.

+

3. Fahren Sie nicht zu schnell.

+

Wenn du die Fahrgeschwindigkeit auf eine sehr hohe Zahl einstellst (z. B. 100), könnte dein Roboter zu schnell für seine Sensoren sein. Dies wird später wichtig sein, wenn wir versuchen, eine schwarze Linie zu erkennen, aber zu schnell über sie fahren.

Mein drittes Programm

+

Der offizielle compAIR-Bot ist mit einer Reihe von Sensoren ausgestattet. Die wichtigsten sind die Infrarotsensoren und -sender, die an der Vorderseite des Roboters angebracht sind. Insgesamt gibt es fünf IR-Sensoren.

+

Um loszulegen, muss man zunächst das entsprechende Modul wie folgt importieren:

+
1
from compLib.IRSensor import IRSensor
+
+
+

irSensor

+

Wie im obigen Diagramm zu sehen ist, verfügt jeder Sensor auch über einen entsprechenden IR-Sender / Emitter. Dieser Sender kann mit IRSensor.set(port, enable) aktiviert werden.

+

Schalten wir nun alle fünf Sender ein:

+
1
+2
+3
from compLib.IRSensor import IRSensor
+
+IRSensor.enable()
+
+
+

Diese fünf verschiedenen Sensoren befinden sich an der Vorderseite des Roboters und sind wichtig, um schwarze Linien zu erkennen.

+

Es ist sehr einfach, den Wert der Sensoren abzulesen:

+
1
+2
+3
+4
+5
+6
+7
+8
from compLib.IRSensor import IRSensor
+
+IRSensor.enable()
+
+if IRSensor.read_all()[0] > 500:
+    print("high")
+else:
+    print("low")
+
+
+

Erkennen einer schwarzen Linie +Um den IR-Sensor zu testen, kannst du deinen Roboter auf eine schwarze Linie stellen. Der Sensor in der Mitte sollte auf der schwarzen Linie liegen.

+
1
+2
+3
+4
+5
+6
+7
+8
+9
from compLib.IRSensor import IRSensor
+
+IRSensor.enable()
+COLOR_BREAK = 900
+
+if IRSensor.read_all()[2] > COLOR_BREAK:
+    print("Robot is standing on a black line")
+else:
+print("Robot is NOT standing on a black line")
+
+
+

Wenn das Programm ausgeführt wird, zeigt es an, dass der Roboter auf einer schwarzen Linie steht, wenn sich der mittlere IR-Sensor des Roboters über einer schwarzen Linie befindet, und es zeigt an, dass der Roboter NICHT auf einer schwarzen Linie steht, wenn sich der mittlere IR-Sensor nicht über einer Linie befindet.

+
+
In Zeile 1 importieren wir das IRSensor-Modul, das zur Kommunikation mit dem IR-Sensor-Board verwendet werden kann.
+
In Zeile 3 wird der Sensor mit der Nummer 3 aktiviert. Wenn wir einen Sensor nicht aktivieren, können wir ihn nicht in unserem Programm verwenden.
+
In Zeile 4 stellen wir einen Farbschwellenwert von 900 ein, mit dem wir später prüfen werden, ob der Sensorwert unter oder über diesem Schwellenwert liegt. Unterhalb bedeutet, dass sich eine helle Farbe unter dem IR-Sensor befindet und ein höherer Wert als 900 bedeutet, dass sich eine dunkle Farbe unter dem IR-Sensor befindet.
+
+
+
In Zeile 6 lesen wir den Sensor Nummer 2 aus und prüfen, ob der Wert über dem von uns definierten Schwellenwert von 900 liegt. Wenn das der Fall ist, hat der IR-Sensor eine schwarze Linie erkannt.
+
+

Wir werden nun das Programm so ändern, dass es alle 0.1 Sekunden prüft, ob sich eine schwarze Linie unter dem Roboter befindet, und wenn dies der Fall ist, eine Meldung ausgibt.

Software Updaten

+

Da wir die compLib, und die andere Software, welche auf dem Roboter läuft, laufend weiterentwickeln, solltet ihr immer wieder euren Roboter auf die neuste Version updaten. Dazu müsst ihr einfach den Roboter mit dem Internet verbinden und dann diesen Befehl in der Kommandozeile des Roboters eingeben:

+
sudo apt update && sudo apt upgrade
+
+
+

Am einfachsten kann das über die Webseite gemacht werden, auf der ihr auch euren Code schreibt. Dazu müsst ihr einfach nur das Terminal (= Konsole) öffnen, dann den Befehl dort hineinkopieren und Enter drücken. +updatePic

WLAN-Verbindung herstellen

+
+

Schritt für Schritt - macOS

+
    +

  1. SD-Karte aus dem Raspberry Pi bzw. Roboter entnehmen.

    2. +

  2. Einstecken der SD-Karte in den Computer

    3. +

  3. Öffnen der SD-Karte mit dem Namen „boot“ bootImage

    4. +

  4. Generieren des PSK auf https://www.wireshark.org/tools/wpa-psk.html pskImage

    5. +

  5. Öffnen der Datei „wpa_supplicant.conf“ auf der SD-Karte

    6. +

  6. Einfügen der Konfiguration. Dabei muss die SSID und der vorher generierte PSK eingesetzt werden

    +
    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
+update_config=1
+country=AT
+
+network={
+    ssid="EinTollerNameFürDasWlan"
+    psk="98117b165a48f25cbe36f288ddf597729a40feeea93054c19bfa8e5eab238541"
+}
+
    +
    +
    7. +

  7. Speichern, Auswerfen und wieder in den Raspberry Pi einbauen

    8. +

  8. Starten des Roboters

    9. +

  9. Die IP-Adresse sollte nun am Roboter angezeigt werden

    10. +
+
+
+

Weitere Informationen

+

Die „wpa_supplicant.conf“ Datei wird beim Start des Rpasberry Pi automatisch an den richtigen Ort kopiert, damit sich der Roboter zum Wlan verbindet. +Eine genauere Anleitung wird vom Hersteller des Raspberry Pi hier bereitgestellt.

+
+
+

Windows……

+

Je nach Betriebssystem und Editor, mit dem Sie die Datei erstellen, könnte die Datei falsche Zeilenumbrüche oder eine falsche Dateierweiterung haben; stellen Sie also sicher, dass Sie einen Editor verwenden, der dies berücksichtigt. Linux erwartet das Zeilenumbruchzeichen LF (Line Feed). +Beispielsweise kann Notepad++ verwendet werden, um die Datei richtig zu speichern. +notepadImage

+
+
+

Fehlerbehandlung

+

Sollte es dazu kommen, dass der Roboter nicht automatisch die Verbindung mit dem Netzwerk herstellt, kann eine Kabelgebundene Verbindung zur Diagnose von Fehlern genutzt werden. +Dabei wird automatisch die IP-Adresse der Verbindung „eth“ am Roboter angezeigt. Nach der erfolgreichen Verbindung zum Roboter mittels SSH kann die „wpa_cli“ zur Fehlerbehandlung verwendet werden:

Calling Double Elimination API

+print(f"Goal is at: x={goal.x}, y={goal.y}, the server responded with status code: {status}")
+
+
+
from compLib.Api import DoubleElim
+import time
+
+# function which waits for the game to be started (you should include this in your double elimination program)
+def wait_for_start():
+    _, status = DoubleElim.get_position()
+    while status == 503:
+        time.sleep(0.1)
+        _, status = DoubleElim.get_position()
+
+wait_for_start()
+print(f"Game has started, lets score some points!!")
+
+position, status = DoubleElim.get_position()
+print(f"Position of my robot is: x={position.x}, y={position.y} and rotation is: {position.degrees}, the server responded with status code: {status}")
+
+opponent_position, status = DoubleElim.get_opponent()
+print(f"Position of the opponents robot is: x={opponent_position.x}, y={opponent_position.y} and rotation is: {opponent_position.degrees}, the server responded with status code: {status}")
+
+goal, status = DoubleElim.get_goal()
+print(f"Goal is at: x={goal.x}, y={goal.y}, the server responded with status code: {status}")
+
+items, status = DoubleElim.get_items()
+print(f"There are currently {len(items)} on the gameboard: {items}, the server responded with status code: {status}")
+
+score, status = DoubleElim.get_score()
+print(f"The current score of the game is {score}, the server responded with status code: {status}")
+
+meteoroids, status = DoubleElim.get_meteoroids()
+print(f"The current meteoroids in the game are {meteoroids}, the server responded with status code: {status}")
+
+
+

In this second example we wait until the game is started by the judges and then make all possible requests once. You should use the wait_for_start function in your double elimination program. If your robot starts too soon your run will not count!

Recognizing ArUco tags

+
import time
+import cv2
+from cv2 import aruco
+from compLib import Vision
+
+ARUCO_DICT = cv2.aruco.Dictionary_get(aruco.DICT_6X6_250)
+ARUCO_PARAMETERS = aruco.DetectorParameters_create()
+
+def getTagCenterFromFrame(id, frame):

+
+    if ids is None:
+        return frame, None, None
+
+    for tag_id, corner in zip(ids, corners):
+        if (tag_id[0] == id):
+
+            x, y = 0, 0
+            for i in range(4):
+                x += corner[0][i][0] * 0.25
+                y += corner[0][i][1] * 0.25
+
+            return frame, x, y
+    return frame, None, None
+
+# Get the center from the aruco tag with the specified id
+# in pixel coordinates (0-640, 0-480)
+def getTagPosition(id):
+    frame = Vision.Streaming.get_frame()
+    frame, x, y = getTagCenterFromFrame(id, frame)
+    Vision.Streaming.publish_frame(frame)
+    return x, y
+
+# Get the normalized center coordinates from the aruco tag
+# with the specified id
+# left is -1, right +1
+# bottom is -1, top +1
+def getNormalizedTagPosition(id):
+    frame = Vision.Streaming.get_frame()
+    frame, x, y = getTagCenterFromFrame(id, frame)
+    Vision.Streaming.publish_frame(frame)
+
+    if x is None or y is None:
+        return None, None
+
+    height, width = frame.shape[:2]
+    x = x / width * 2.0 - 1.0
+    y = -(y / height * 2.0 - 1.0)
+    return x, y
+
+if __name__ == '__main__':
+
+    desiredID = 11
+
+    while True:
+        x, y = getNormalizedTagPosition(desiredID)
+
+        if x is not None:
+            print("X Coordinate: ", x)
+        else:
+            print("Tag not found")
+
+
+

This example shows how to recognize ArUco tags based on their id and position. +You can specify an ID of the tag you want to use and if it’s found, the coordinates of the center are returned. +With the normalized function this is very easy: The x-coordinate is -1 on the left, 1 on the right and 0 in the center of the screen, same for y. +This way it is quite simple to act on the position of the tag.

Vision

+

This module provides an interface for grabbing an rtmp stream and using the images to do some processing in opencv.

+

How do I use this module?

+
    +

  1. Get frames from the raspberry pi camera

    2. +

  2. – here comes your own processing –

    3. +

  3. Publish the processed frames on an http server

    4. +

  4. You can view the http stream of your processed images in a web browser

    5. +
+
+

Opencv Stream

+

Because of the rtmp stream needing to buffer some frames and waiting for P-Frames, importing this module might take up +to 5 Seconds.

+
+
+class compLib.Vision.__Streaming
+

Class that handles rtmp streaming for opencv.

+

DO NOT CREATE AN INSTANCE OF THIS CLASS YOURSELF!

+

This is automatically done when importing this module. Use Vision.Streaming which is +an instance of this class!

+

grab frames -> do your own processing -> publish frame -> view on http server

+
+
+get_frame()
+

Grab the newest frame from the rtmp stream.

+
+
Returns
+

An opencv frame

+
+
+
+ +
+
+publish_frame(image)
+

Publish an opencv frame to the http webserver.

+
+
Parameters
+

image – Opencv frame that will be published

+
+
Returns
+

None

+
+
+
+ +
+ +
+
+

Examples

+
+

Using the Vision Module

+
import cv2
+from compLib import Vision
+
+while True:
+    # get newest opencv frame from camera
+    frame = Vision.Streaming.get_frame()
+
+    # do some processing with the frame.....
+
+    # publish frame to streaming server
+    Vision.Streaming.publish_frame(frame)
+
+
+

Connect the raspberry pi to your internet and view the stream at: “http://your_raspi_ip:9898/”. This should display +your raspberry pi camera. Note: the stream will lag a little bit BUT the processing of the image will be done in +realtime.

+

The output on the website should show whatever your raspberry pi cam records:

+Processed frames from opencv +
+
+

Chessboard Detection

+

In this example we process the captured stream of images and want to detect chessboards. Run this example and +point your raspberry pi camera to a chessboard and it should be detected.

+

For testing you can point it at this image:

+Chessboard for opencv processing +
import cv2
+from compLib import Vision
+
+while True:
+    # get newest opencv frame from camera
+    frame = Vision.Streaming.get_frame()
+
+    criteria = (cv2.TERM_CRITERIA_EPS + cv2.TERM_CRITERIA_MAX_ITER, 30, 0.001)
+
+    # convert image to grayscale image
+    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
+
+    # find the chessboard corners
+    ret, corners = cv2.findChessboardCorners(gray, (6, 9), None)
+
+    # draw detected chessboard position onto the image
+    cv2.drawChessboardCorners(frame,  (6, 9), corners, ret)
+
+    # publish frame to streaming server
+    Vision.Streaming.publish_frame(frame)
+
+
+

Connect the raspberry pi to your internet and view the stream at: “http://your_raspi_ip:9898/”.

+

The output image should look like this:

+Processed frames from opencv +

Here is a screenshot of the stream website while viewing the chessboard in this documentation.

Power vs Speed vs PulseWidth

+

Zur ansteuerung der Motoren kann entweder Motor.power(...), Motor.speed(...) oder Motor.pulse_width(...)` verwendet werden. +Der Unterschied der 3 Funktionen liegt dabei in der Einheit des 2. Parameters.

+
+
Bei Motor.power() wird dabei ein Wert zwischen -100% und 100% der maximalen Geschwindigkeit angegeben.
+
Motor.speed() verwendet die Encoder um die Geschwindigkeit der Motoren mittels closed-loop zu steuern. Diese Funktion sollte nur verwendet werden, wenn Motor.power() nicht zur Ansteuerung ausreicht.
+
Motor.pulse_width() stellt die Geschwindigkeit des Motors mittels der Pulsbreite der PWM-Steuerung des Motors ein. Diese Funktion ist so nah an der Hardware wie möglich und sollte auch nur verwendet werden, wenn es einen expliziten Grund dafür gibt.
+
+
+
+

Normal vs Multiple

+

Der Aufruf der funktionen kann entweder über Motor.power(port, percent) oder Motor.power((port, percent), (port, percent), ..) erfolgen. +Der zweite Aufruf ermöglicht dem Entwickler dabei beide Motoren in einem Aufruf anzusteuern und bringt einen kleinen Vorteil in der Leistungsfähigkeit der Software.

+
+
+
+

Beispiele

+
+

Vorwärts fahren

+

Mit folgenden Programm drehen sich beide Motoren mit 50% ihrer maximalen Geschwindigkeit. +Dabei ist zu beachten, dass ein Motor in die entgegengesetzte Richtung zum aneren Motor gedreht werden muss, da diese spiegelverkehrt montiert sind.

+

Zusätzlich ist ein time.sleep(5) notwendig, welches das Programm für 5 Sekunden pausiert. Diese Pause wird benötigt, da der Roboter automatisch alle Motoren beim Ende des Progammes deaktiviert.

+
from compLib.Motor import Motor
+import time
+
+Motor.power(0, -50)
+Motor.power(3, 50)
+
+time.sleep(5)

Rückgabe
+

Ein „opencv image frame“

+
+
+
+ +
+
+publish_frame(image)
+

Sendet das Bild, welches der Funktion übergeben wird, an den Webserver, damit es der Nutzer in seinem Browser ansehen kann.

+
+
Parameter
+

image – Opencv Bild, welches dem Nutzer angezeigt werden soll.

+
+
Rückgabe
+

None

+
+
+
+ +
+ +
+
+

Beispiele

+
+

Bild Anzeigen

+

Das folgende Programm fragt Bilder von der Kamera ab und schickt sie an den Webserver, der im Hintergrund läuft. Der Benutzer kann dann auf die Webseite: http://raspi_ip:9898 gehen und die Ausgabe der Kamera sehen.

+
from compLib.Camera import *
+
+camera = Camera()
+while True:
+    image = camera.get_frame()
+    camera.publish_frame(image)
+
+
+
+
+

ArUco Marker Erkennen

+

In diesem Programm werden die ArUco Marker, die sich am Spielfeld befinden, erkannt. Diese „QR-Code“ ähnlichen Marker finden sich in den Logistikzonen und können dazu verwendet werden zu erkennen, wo der Roboter hinfahren sollt etc.

+
from compLib.Camera import *
+
+camera = Camera()
+while True:
+    image = camera.get_frame()
+
+    markers, image = camera.detect_markers_midpoint(image)
+    print(markers)
+    print("-----------------")
+
+    camera.publish_frame(image)
+
+
+

Hier ist z.B. der ArUco Marker mit der ID 0. Führe das Programm aus und lass den Roboter auf den Bildschirm schauen. Das Programm sollte die 2D Position ausgeben, welcher der ArUco Marker (genauer sein Mittelpunkt) im Camera Bild hat.

+

ArucoExample

+

Um die Positionen zu verarbeiten, muss dann nur noch das „markers“ array durchgegangen werden. Das könnte z.B. so gemacht werden:

+
from compLib.Camera import *
+
+camera = Camera()
+while True:
+    image = camera.get_frame()
+
+    markers, image = camera.detect_markers_midpoint(image)
+    print(markers)
+    print("-----------------")
+
+    for marker in markers:
+        print(f"Marker mit der id: {marker.id}")
+        print(f"Ist auf der X Position: {marker.x}")
+        print(f"und auf der Y Position: {marker.y}")
+        print("-----------------")
+
+    camera.publish_frame(image)
+
+
+

Wichtig ist noch zu beachten, dass die X und Y Positionen ihren Ursprung in der linken oberen Ecke des Bildes haben. D.h. die Position (0,0) ist im oberen linken Bildrand.

Seeding

+
+

Dokumentation des Seeding Moduls

+
+
+class compLib.Seeding.Gamestate(seed: int)
+

Erstellt den Seeding „Gamestate“ für den angegebenen Seed.

+
+
Parameter
+

seed – Seed welcher zum Erstellen des Gamestates benutzt werden soll.

+
+
+
+
+get_heuballen() → int
+

Die Funktion gibt entweder die Zahl „1“ oder „2“ zurück. Wenn die Funktion „1“ zurückgibt, dann liegen die Heuballen auf den gelben Linien. Wenn die Funktion „2“ zurückgibt, dann liegen sie auf den blauen Flächen.

+
+
Rückgabe
+

Gibt entweder die Zahl 1 oder 2 zurück.

+
+
+
+ +
+
+get_logistic_plan() → ]
+

Die Funktion gibt den „Logistik Plan“ zurück. Also die Reihenfolge, in welcher der Roboter die Logistik Zonen Abfahren muss, um die Pakete welche dort liegen zu sortieren.

+
+
Rückgabe
+

Eine Liste an Zahlen zwischen 10 und 13.

+
+
+
+ +
+
+get_material_deliveries() → []]
+

Die Funktion gibt die einzelnen „Material Lieferungen“ zurück. Da der Roboter immer zwei Paare an Materialien anliefern muss, gibt die Funktion eine Liste an Material Paaren zurück. Die Materialien werden dabei durch ihre Zonen-ID representiert. Also Holz ist z.B. „0“ und die Ziegelsteine sind „3“.

+
+
Rückgabe
+

Eine Liste and Material Paaren.

+
+
+
+ +
+ +
+

Beispiele

+
+
In Zeile 1 wird das Seeding Modul importiert.
+
In Zeile 2 definieren wir dann eine Variable, in der wir den „Seed“ des Gamestates den wir erstellen wollten speichern.
+
In Zeile 3 erstellen wir dann einen neuen Gamestate mit dem Seed und speichern ihn in die Variable gamestate.
+
In Zeile 4 geben wir dann den Gamestate aus, damit wir ihn auf der Konsole ansehen können.
+
+
import compLib.Seeding as Seeding
+seed = 42
+gamestate = Seeding.Gamestate(seed)
+print(gamestate)
+
+
+

In der Ausgabe des Print Statements sehen wir den generierten Gamestate.

Hardware

+
+

Sensorarray

+

SensorarrayImage

+
+

Specs V4

+
+
Processor: STM32G030F6P6 - 32-bit ARM Cortex M0 CPU @ 64 MHz
+
I/O: 1x I2C, 1x SWD
+
Sensors: 5x QRE1113GR
+
+
+
+

Specs V2

+
+
Processor: ATMEGA328P-AU - 8-bit CPU @ 16 MHz
+
I/O: 1x I2C, 1x UART, 1x ISP
+
Sensors: 5x QRE1113GR
+
+
+
+

Details

+

Das Sensorarray wird verwendet um Linienen vor dem Roboter zu erkennen. Es agiert als I2C Slave und muss dementsprechend aktiv gepollt werden. +Zusätzlich besteht die möglichkeit alle Emitter zu deaktiviern um einen eventuellen Messfehler durch Sonneneinstralung oder andere Störquellen zu erkennen.

+

Version 4 unterscheidet sich zu Version 2 im Mikroprozessor, da es zu Lieferengpässen des ATMEGA gekommen ist. +Zusätzlich wurde die möglichkeit alle Emitter einzeln an bzw. auszuschalten entfernt, da diese keinen signifikanten Mehrwert brachte.

+
+
+
+

Motorboard

+

MainboardImage

+
+

Specs

+

Motor-Treiber: LV8548MC-AH

+
+
+

Details

+

Das Motorboard kann an einen der 4 Ports am Roboter angesteckt werden und ermöglicht das Ansteuern von Motoren und auslesen von Encodern.

+
+
+
+

Mainboard

+
+

Specs

+
+
Processor: STM32L051C8T6TR - 32-bit ARM Cortex M0 @ 32MHz
+
I/O: 4x I2C (3x Bus 1, 1x Bus 2), 1x 40 Pin GPIO Header, 2x SPI (Verbunden mit GPIO), 4x Motor-/Servo-connector, 1x SWD, 1x USB-C
+
+
+
+

Details

+

Das Mainboard wird auf den GPIO-Header eines Raspberry Pi gesteckt und ermöglicht die Steuerung eines Roboters mittels 4 Motor- bzw. Servo-Ports. Der RaspberryPi kommuniziert dabei mittels SPI mit dem Mainboard und steuert die einzelnen Sensoren oder Module an. +Zusätzlich befinden sich auf der Unterseite des Mainboards Lötstellen, welche direkt mit der Stromversorgung der Motoren verbunden sind und geben so die möglichkeit Motoren mit mehr als 5V anzusteuern.

Installationsanweisungen

+

Diese Anleitung dient dazu die Software auf dem Roboter neu aufzusetzen.

+

Im normalen Gebraucht sollte dies jedoch nicht notwendig sein.

+
+

Betriebssystem aufsetzen

+

Als Basis wird für den Roboter Raspberry Pi OS (64-bit) verwendet. Das 32-Bit Betriebssystem wird nicht unterstützt, da die Software-Komponenten nur für aarch64 bzw. arm64/v8 kompiliert werden. +Genauere Informationen sind hier zu finden.
