In 1999 our robot had a chronic problem which we were never able to solve. The problem involved the speed control of our main drive system which consisted of Victor speed controllers and the drill motors. When slowly accelerating the robot from a standstill, at about half speed, one side would stop as the other continued to accelerate. If you went to full on both sides the drives would go to full speed. This is how we would compensate. When we bench tested each drive system, they'd work perfectly individually. Never any glitches. It almost seems like the processor is having trouble with the math or something. We run a custom program, but it does it on the default program too.
Has anyone else seen this on thier robots?
