A worm gear mounted against a 40t gear is, I believe, the 2-gear combination
that provides the most torque. You may want to gear down the worm gear
first, providing even more torque. In general, as speed decreases (assuming
the decrease is caused by "gearing down," not slowing the motor), torque
increases.
Sounds like a fun project. Hope you can share pictures.

| Thanks for the help! After sending out the email, I thought of a way to do it (using a worm and a 40t gear ;), so now it lifts its self. Its interesting to watch as it rises though, because even though its semetricle, it goes up on first one leg, (...) (24 years ago, 21-Sep-00, to lugnet.robotics)
