Re: Limitting motor torque

This was discussed a lot in 2009. Some teams used a form of Traction Control, some didn't.

One of the most simple ways to implement a form of TC was to program in a 'ramping' function so that the driver couldn't go from 0% (standstill) to 100% and spin the wheels.

Another method is to have an array of follower wheels that keep track of robots actual speed and compare this to the speed that the wheel is spinning at, if the two speeds are different, then your wheels are slipping and you adjust the motor motor speed accordingly.
