[Robotgroup] Robot Challenge Help Needed

[Paul Atkinson]

Gray,

I think if you accommodated the mini sumo form factor and the RC-40 that
Eric mentioned, that would be a good start. Tab Books had a "Sumo-bot" which
is slightly larger than sumo should be. I've got 2 of them somewhere that I
could compete with if we can find dimensions someplace.


Mini-sumo is 10cm x 10cm or approx 4" square with no height limit. Standard
"Japanese" sumo class is 20cm x 20 cm or approx 7.8" square with no height
limit. Something in the 6" square range would let mini-sumo also run this
course.

Also, I sent you some questions about the competition on Friday, off list.
Since I missed most of your presentation, could you oblige me and give some
idea of what the contest is about?

Thanks,
Paul
