Is the brake on the motors with the suggested gearboxes enough to keep the robot up when disabled?
What motor and gearbox/ratios are you using to power your climber?
We used 28:1 off a Falcon with no issues staying up in Brake Mode during Week 0.
We have a bit of a hybrid. It is using a climber in a box wench and thrifty bot bearings and sliders. We have two arms with 16:1 and a single Neo on each. In brake mode the bot slowly comes down after a match. I would say less than 0.5 inch per second or so.
20:1 with neo and a 2.5cm shaft, which is equivalent to Andymark’s recommend 16:1 with 2cm shaft.
