I used 2 dc motor in control my robot car.
both motor are same type and supply voltage also same.
But there still not able to run in same speed, hence make the robot not able move in straight line.
Since, before that i not realize is it a better way to use the dc motor with encoder, so it cause me trouble now.
May i know any other method to solve this problem? or i can make the encoder and interface with my motor? (my motor do not have back shaft!!!)...dunno how to connect the optical disc encoder also...
hope anyone can give me advice. thanks...
