In my opinion, this is a better example of a not leaving enough meat on the bone than the power of the F-P motors.

Actually power had nothing to do with this failure, I suppose it was torque that killed it not torque X speed (i.e. power).

Yep, the sprocket was supposed to see only torque from the Window motors (very weak), but because we were still learning with the arm we hung incorrectly. This put the torque of 2 FP's reduced 10:1 on the sprocket. Unfortunately when you try to do a lot of tasks (big ball, hang, climb, push) with your robot, weight becomes a big issue REAL FAST. This requires the team to lose a little bit of robustness. This is what it's all about though, making the simple parts to replace the weak link. We replaced the sprocket within 5 minutes and had time to eat before our next match. We have learned a lot over the last 5 years. We also ripped off an robot finger trying hang incorrectly and blew out our trick wheels when the bot fell. It was awesome, our arm was still on the bar. I think we should have gotten 50 pts. for it.

Oh course Fisher price motors are powerful *opens gear box and gazes at big gears!* They also are made to move up to arund 150 pounds, so if its moving your arm...that alot of power for not so much weight.
