Getting the robot ready to drive

Recently I have been working on mounting the drive motor on the left side of the robot. I got another belt for the other side and I think i'm going to have to buy another motor controller. Hopefully I can find one on eBay or something. Also, I attached a tensioner to keep the belt tight against the pulleys but after the first test I think I will also have to make some teeth to fit the rigid inside of the belt because it is slipping to much.

Motor controller, motor and fuse box mounted.
