Tutobot : schematics for the PCB

These last days we have been working on schematics for our PCB. Each on is working on different parts of it so we can finish it as soon as we can. I’m working on the schematics for our sensors, wheel encoder and motor driver. We had some changes on this yesterday so I have to adjust my schematics, I can post them here latter.

For sensors we are using the QRE1113 as color sensor to follow lines (following the idea of the Pololu’s QTR sensors), and the HSDL-9100-021 as proximity sensor.

For motor choice we ended up choosing the option 3 because the motor has a much better quality ( the option one is rather too noisy…) and because the encoder has a slighly better resolution.
