Nik built a 6 wheel rocker bogie rover (unsteered and straight drive, not
geared) with 6 micromotors. It works, sort of. But as soon as you get in a
little trouble terrainwise, if a motor binds up, you're done for. Those motors
bind easily and you then are picking it up and unbinding motors to get it to
work again.
