Ill take a picture today and post it.
This is our first year ever having chain issues, and last year we had a VERY similar drive system with 1 cim per side instead of 2. We never had problems with that.

This is a big factor in your jumpiness. With the four cims you have more power when accelerating so you will do so at a faster rate. If you have a slightly higher CoG your robot will "jump". The reason one cim per side won't do this is because you are accelerating slower because you have less power in your base. You could try fixing this by altering your drive program to slow down your acceleration rate from a dead stop and while reversing directions. Additionally, if you keep your CoG low, your robot will have increased maneuverability and a lower chance of tipping. The past two seasons we have kept our robots below 3ft with most of the weight within 6in. of the ground.
