So, you're best option would be to increase the speed.

Finally, remember, you can mechanically connect all the motors together, so
they are driving the same wheels.  This assures all wheels are getting the
maximum amount of power.

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'.

(...) One rotation sensor and a differential will allow you to compare the rotation of two wheels. If the driven wheel and the undriven wheel come in the two sides of the differential, and the rotation sensor is connected to the drive ring, then the (...)

(...) 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)

(...) I suspect you're far from breaking gears or axles. However, keep in mind it is always possible (so don't blame me if it happens) :) Keep the distance between gears & wheels small, so the axles don't twist. Sounds like you still have more (...) (18 years ago, 5-Jun-06, to lugnet.robotics)
