<p>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.</p>
|
|
<p>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.</p>

<p>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.</p>
