Maybe I did not phrase my problem clearly. It's better described in Jon
Shemitz's recent post <http://www.lugnet.com/robotics/?n=5804>.
In my experience, wheels are more efficient than treads. Under the same load,
my wheel-based design outrun my tread-based design. However, without a
steering mechanism, the "corner" wheels will produce significant sideway drag
while the robot is turning in place. How does a differential gear solve this
problem?
(This problem does not occur on the two- or three-wheel designs. However,
these designs are usually not very stable.)
Cheers,
