Re: Making your robot drive easier

All you need is 1/4 of an inch maybe less, This allowed us to actually TURN with 12.5" wheels (allot of bots couldn't turn that didn't have a sixth wheel and still had 12 inch wheels) , this way if we decided not to hang we could stilll go around the field and stuff.
PID is pretty cool we haven't tried it but it is way better because then you control the amount of acceleration during turning not simply the voltage ... this works esp good on arms where as you go straight up the lever arm is significantly lower then at 90 degs so less voltage is req'd for the same amount of acceleration...the computer compensates...so the driver doesn't have to jerk the stick back and forth
