Options for preventing gearbox backdrive:
- Add a ratchet mechanism. This can take the form of a fancy ratchet and pawl purchased from McMaster or SDP-SI, or a 1/2" hex wrench purchased from Harbor Freight. YMMV.
- A worm drive with a lower lead angle. The lower the angle the more difficult they are to backdrive.
- An anti-backdrive planetary gearbox from a DeWalt drill or something similar. Look into the Nothing But DeWalts whitepaper here on CD from some years ago. There is some effort in interfacing an FRC legal motor with one but very doable.
- Use one of the anti-backdrive motors we're given, like the Window Motor. The idea of pairing this with a higher powered motor was brought up in another thread. I'm currently investigating some options on this one.
