Re: Turning Trouble!

The Dukes (991) had the same problem. We found that there are a number of fixes that work for this. The aforementioned cable ties or else vacuum hose cable-tied onto the wheels work but they don't look very attractive.
If you have the option to gear down, then that will help.
Those were our 2004 solutions.
This year, we were having the problem with bouncing through turns, but when we started testing auto mode the robot was turning as smoothly as silk. This points to a software problem.
In RC mode, we're tank drive, so it's hard to get the same exact power output to each side while turning. To remedy that, we programmed a button on each joystick to turn the robot in place by sending equal (but opposite for each side) power to the motors. That worked for us!
BTW- we're using the 8" Skyway wheels.
