This is a weapon spin-up test of my 3lb combat robot, Bezek. This was Wednesday night before RoboGames 2017, so I didn't hit anything because if something broke I wouldn't have time to fix it. My goal with this test was to stop the top nut from vibrating loose and not have any traction magnets fly off. I succeeded on both counts and mechanically the bot was very reliable at RoboGames.
