[Robotgroup] Robot Challenge Help Needed

[Doug Evans]

I still have a few of the CR-01 chassis that Eric calls his "blue robot".

These were designed originally to fit within the specs for the DPRG desktop
competitions. They have mounts for two standard servos.

Anyone interested should contact me off-list - I'd be happy to unload these
at cost or lower.

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
