Thanks!

Hopefully I'll have some time to check this bot out in STL.
The cord from the window motors are belt-drives for the gripper. It's so long because we wanted the motors back at the pivot point of the arm so the torque required to move the arm is as small as possible.

For the gearing, it's actually direct drive off of the window motors. We have bigger pulleys driving the gripper now, which makes it a little faster.
