R2 Drive System

Here are some photos of what is in my R2 now.  The top and bottom tubings are bolted together at the front and the rear.  The shelf to the left is cut from aluminum angle and is the shelf where the battery will sit.  In my new R2 it is slightly different.  What connects the drive system to the leg is rectangular tubing cut to shape and is bolted directly to the drive system and the leg.  This makes the entire leg assembly very rigid.

I distribute the weight of the droid I used the front wheel bolted to the rear wheel to get dual wheels.  This will make it easier to drive on plush carpet.  When transporting R2 I can thread a strap through the lower lip to hold R2 to anchor points in my vehicle.

Notes: I made the drive system as big as possible to fit under the foot shell so if the foot shell gets hit a lot of the forces will go into the drive system and hopefully not damage the foot shell.  The drive system gives me a good lifting point if needed.  I can wrap a strap through the drive system to belt in my droid to anchor points in my vehicle to prevent it from moving forward during sudden stops or an accident.
