Using dual motors in Chain-Drivesystem

[sanddrag]

We did last year exactly what your original question was. You can see some pics on the various pages here: http://www.team696.org/forum/category.php?cid=5 It was very simple and worked fairly well. We used the kit pillow blocks and mounts on the drill motor and kept it in high gear. That drove a 10/48 reduction to the wheels. The chia was geared down directly to the drill shaft 10/35. There were a lot of issues with misalignment and overly tight chains and binding. It was a very high drag high current draw design (partially due to having 4 separate pillow blocks as you can see in our pics). However, it worked and it worked better than many out there. We seeded third in Phoenix making it to the semifinals and made it to the finals in LA. We also participated in an off season event and an exhibition event and a few demonstrations and the robot still is driving today (although it has gotten a little louder). If you have any questions about it, feel free to ask.

This year, we are gearing the Chias through a two stage GEAR reduction to match the low speed of the drill in our all new "QuadraMax G2" It is basically a slight redesign of the team 716 2003 single speed tranny.
