Re: Differential?

In 2001 we wanted a differential but did not have the space & weight to implement it or means to manufacture one. A differential is a complex device that can be tough to properly use in FIRST environment.

In 2001 we solved our problem using s software differential and driving each wheel with a different motor. The software read the angle of steering and scales the PWM signal to the wheels based on how extreme the angle was. Another great way to implement a software differential would be to use encoders on your wheels if they are independently driven. Inputs to determine the "differential" speed could be from a potentiometer on your steering array or a command signal from the operator interface based on what your driver is doing.

Good luck,
