Talking with my physics, he has assured me that using a CIM to lift the robot would definitely suffice, and it'd be fast too.

And for those who are considering a worm gear, a worm gear will rip itself apart before it goes against the motor, but they are extremely slow. And I mean EXTREMELY slow. IMO, it'd take at least 10-15 seconds to get up beyond the 20".

*ahem* A 30:1 reduction with a 2" pulley will lift a bot in under 4 seconds. In fact, a 2" pulley needs at least a 14:1 reduction just to get to half stall torque. So you need a reduction in the worm gear range unless you're using extremely small pulleys and beating up your motor.
