Re: Elevator/Telescopic Arms & Motors to Use
For Logomotion we built a two stage timing belt elevator that was fast and had sub inch accuracy on the set points. We started with one Fisher Price motor but added a second one when we re-geared the transmission to make it scary fast. I was surprised to see how easy the elevator was to build and how reliable it was through the season. Rivet construction. External fan cooled motors, Jag speed controllers. The timing belt was the key to our elevator. We didn't need a counter spring to lower. We caught a peg in a match and the elevator lifted our 140 lbs bot no problem. FYI don't use the KOP limit switches use a industrial strength limit switches to prevent the over travel.
Here is how 971 ran their bearings on the elevator.

We used Igus cable carriers to do the cable management
