Re: Eliminating Arm Wobble

A good solution I have seen is to add a system with a piston-actuated bolt that slides into a notch to physically lock the arm in a certain position. Good examples are 254's Shockwave and 118's 2014 robot.

Main thing with this method is to MAKE SURE that you aren't stressing the piston's shaft anyway other than linearly. This means don't use the piston's shaft as the bolt, isolate it.

This was the main mechanism that caused my team copious amounts of pain at Northern Lights. I'm not really sure if there's a better way to do it and genuinely lock it in place, though.
