Go to Post In my opinion, the hardest part of the competition is not that actual manufacture of the robot, but the design process. It is the enginners that go through the design process all the time that will have the edge in this competition, not the best machinist. - Wetzel [more]

Re: PID traction Control

Thanks. I was informed (in so many words) that we are not going with Daniel_LaFleur's idea. I wrote the code for that and asked if someone could check it over. I was then refered to a link about PID in LabView. They don't just want to keep the wheels spinning at the same rate. They also want this to act as an acceleration curve, which is why I was referd to the PID control.

PID is fine for an acceleration curve (and I highly reccommend it), but will not tell you if your wheels are slipping. This will happen when you get into a pushing match.

Re: PID traction Control

I noticed today that WPI has PID control built in. I didn't see that before. I makes more sense now on how to use it. Thanks. Would Q_score logic help any with figuring out the best reaction to slipping, especially if another bot was pushing during autonomus?
