Hello all. I have been working on a robot project with a group of friends and we have encountered a slight problem in making the robot move properly. We decided to use stepper motors as the drive train system. Using stepper motors we know the relative telemetry of the robot but we have no way of compensating for the stepper motor skipping a step or wheel slippage. While debating different solutions we came up with the idea of using two optical mice mounted under the robot facing the ground to track ground movement as a secondary telemetry for correction.
I would like to know if anyone in this group has done this set up before and can post suggestions.
Thanks
Andy
