To interpret this a different way, if you're talking about the robot turning really suddenly and being hard to control, make sure it weighs the full amount. Light weight robots are often squirrely. Also running on carpet vesus tile makes a huge difference.
If the robot IS having the opposite problem ( it's difficult to turn) and you are running a 6/8 wheel drive you can do a couple of things.
1. Change the outer wheels on one/both sides to a lower coefficient wheel. In general FRC terms Omni wheels have the least CoF (aside from Lunacy wheels [ew]) and pneumatic wheels have the most. The old gray rubber wheels were a happy medium between the two. Wedgetop is also a pretty good inbetween after it's been run on for a while.
2. Increase the drop in your chassis. If it is impossible to actually lower the middle wheels with your current design. turning down your outer wheels could work (although less desirable because it changes the surface speed of those wheels relative to the middle.)
3. CoG and tortional stiffness. It's probably too late to change these but your frame stiffness and keeping the robot's Center of Gravity close to the ground are large factors in a high performing chassis.
