tripping breakers/burning motors

[WernerNYK]

Yes, we are having this problem... We are a rookie team that is having problems developing our drive train.

We are using the two drill motors for 4 wheel drive to create a 3:1 ration along with our custom-fabricated tensioners. We at first had 2 wheels bolted together with the sprocket in between and we were tripping breakers whenever we tried to turn on the carpet (We have no problems on smooth surfaces).

Today, we went down to 1 wheel at each position and made new spacers for the axels. It seemed to work a little better, but we are still tripping breakers in a way that is not acceptable (Every few seconds doing 360s).

Does anyone have any experience or ideas on how to resolve this problem?? We also made custom motor mounts....we made sure that they are not "pinching" the motors, but could this be causing this problem?? We are running out of reasons why this may be happening.....
