what motor did you use(arm)

[RyanN]

364 used the small banebots gearbox with the default motor (mabuchi?), and we used a globe motor for our extension.

[IndySam]

we used an AM Planetary Cim gearbox at 181:1. The arm can lift the whole robot.

[Billfred]

Our first stage was a CIM and a 12:1 BaneBots gearbox, reduced another 1:3 (as I recall) through chain to the actual arm. The second stage alternated between a Denso and Keyang motor, although we never quite nailed that.

[Herodotus]

We used two Fisher price motors to move our two jointed arm, and then used a globe motor to rotate it and a window motor to open and close the claw. The problem with using a globe motor for the rotation was that it had no backdriving on it so we eventually broke the gear that was on the arm and had to lock the arm rotation half way through Curie.

One FP Motor (without original FP transmission) on a 64:1 BB transmission driving a 40:1 worm gear assembly for both the base and the arm.

BB RS540 motor in the 64:1 BB transmission that came with the kit for the wrist.
