I see it appears to drive some sort of bar near the drive train.
- How did you achieve such smooth motion on the up and down movement of the intake despite it only being powered on 1 side?
Thanks for releasing your cad! The level of detail and compactness found on this robot has left me speechless.

That gearbox is our hanger winch. One end of the string went there, the other was tied on the other side. That way we didn't have to have a winch gearbox/line centered on the robot and got a 2:1 reduction out of the pulley.
The 2" tube welded solidly to the 1x2 in the intake adds a lot of stiffness. Also, we motion profile the intake so that will reduce the torsional load across the intake.
