Re: Using Encoders

Well, you don't *have* to use encoders. If all you were concerned about was that they were spinning the same rate, just figure out how much faster the other motor can spin, then scale the input to the motor appropriately (using the assumption that the motor response AND the output from the motor controller is linear).

Of course, thats a really quick and dirty approximation, and makes a lot of assumptions. If you want them to be matched using encoders, then you probably want to look into using PID control for this problem. Do a search on the forums, there's lots of stuff about that type of thing there.
