FWIW, here's what I came up with given a couple of weeks:
http://www.cs.tamu.edu/people/jkp2866/cpsc643/explorerbot.html
There are some aspects I was happy with (e.g., easy removal of the RCX,
transmission range of upward pointing RCX, durability of frame)
and others I wasn't (e.g., I didn't have a second differential
to build Leo's adder/subtractor). The report provides more details.
