Can you describe your problem in a little more detail?
1. What sort of drive train are you using? 2WD? 4WD? 1 transmission per 2 wheels on each side?
2. When you say you can turn, do you mean one side drives forward while the other side reverses? Or when you are attempting a forward turn, does one side lock up?
3. Is it hopping? Skipping?
4. What kind of wheels are you using?
5. What is the surface you are testing on?
6. Is your robot at full competition weight?
You get the idea? Without actually being there, you have to provide as much information as possible so that the geniuses here can help you out
