Crab drive wheels

We had a small crew of 7 today, but managed to completely salvage the crab drive wheels from the 2010 robot and prepare them for modifications to the new tires and drive chain.  After a few accidental pokes that corrupted an assembly file and provided an excellent teaching opportunity, we also made substantial progress on the CAD model for the new wheel assembly and sprocket design. The evening was topped off by an excellent dinner prepared by a parent chef. 
We may be science nerds, but we sure eat well!  :-)
