there is no way for the encoder to know where the wheels are.
I've never even heard of a position optical encoder!Just did a quick search on digikey but didnt find anything. Would you happen to have a link to something that might work?I am seriously considering using and encoder with an Atmega168 to store data to the EEPROM or Flash. Then output a PWM output to the main controller through a low pass filter.
The problem is if the robot accelerates in a turn of more than 30 degress the robot has a high chance of toppling over.
