Sumo won''t turn and moves slowly

Eliza, is the name "TAB" on the box for your
SumoBot? The TAB publishing company has made a
"Sumobot" package -- that uses the BasicStamp 2,
so you're still in the right place. The TAB
robot does have 4 wheels, and a rubber o-ring
as a 'tread'.
If so, you should aslo check out the 'tabrobot'
forum. The TabRobot uses a 'co-processor' to
control its wheel motors, and they'll have info
on that on the other forum.
