Steve,
Philo's page on 'Wheels, Tyres & Traction' seems to imply that increased
speed will not make much of a difference or am I reading that wrong?
By 'mechanically connect' do you mean by using two differentials?
The maximum 'safe' gearing down ratio was a general question. I was hoping
for an answer like 'anything below 100:1 is fine'.

What I'm saying is that if the robot is moving along at (say) 3 inches per second - then the drive wheels will get most traction if they are turning at a speed equivelent to 3 inches per second. If they are rotating faster than that (because (...) (18 years ago, 6-Jun-06, to lugnet.robotics)
