Re: Supporting 40lbs Arm with Motor?

Some of you may remember Team Driven's Pizza Box from GKC, Razorback and World Champs, the box weighed 40 or so pounds and we had to use a worm gear box and dual miniCIMs with a 32:1 reduction to lift it. This is a very challenging feat to accomplish. You will not be able to do it with all but the toughest of planetaries with a massive reduction. A banebots 256:1 P60 is only rated at 36 (IIRC) foot pounds of torque and you just double that. Worm gear with a substantial reduction is the way to go.

Worm gears can be ordered to be back drive proof, but beware, cast iron gears can (and will) shatter if they take a shock load (like a sudden hit from your arm being rammed). We had to custom make bronze gears to alleviate this fault
