One way to make the axle stiff is to use mutiple axles. For example, get
one long axle and four equal length shorter axles. Use the four shorter
axles to join two of the largest gears together, using the axle shaped
holes that are off-center on the gear. Then put the long axle through
the gears so that it protrudes on either side. Build two such assemblies
and mount the differential between them (be sure to have some support on
both sides of the differential, as well as at the outer end of the
axle). Drive the axle from one of the large gears on each side of the
differential or on each end of the axle, whichever is convenient.

| After the good suggestions from folks (see the Balancing Bots thread) I did some experiments with using 2 motors to drive one axle (to double the power to the axle) and thought the results might be of interest to others. I first tried having the (...) (24 years ago, 7-Jan-00, to lugnet.robotics)
