Re: Nightmare Repairs At Competition



This is a picture in the middle of the repair. The 'before' -- which I don't have a picture of, unfortunately -- was pretty terrible.

We collided with 360 at full-speed midfield. Our frame, which wasn't designed to play the kind of defense we ended up playing in Portland because of a too-complicated collection system, completely collapsed. The front cross member bent inward as far as the intake roller and split in half at one of its rivet holes. The left-side frame rails collapsed as well. There are ripples in the flanges along the entire length of the left-side of the robot.

The rear-mounted gearbox and final gearing stage were knocked wildly out of alignment. The gear mesh distance was busted up and destroyed the teeth on the final gear attached to our wheel. None of the wheels remain planar with one another.

We fixed it with a hammer and by riveting some aluminum angle along the front edge of the robot to keep everything square. The drive gearing remained mostly broken for the rest of the event; we were able to adjust it before each match so we could drive, but it'd go bad by the end.

We're replacing some of the frame parts at our event this weekend and replacing the gear stage with another chain and sprocket stage. We've also rebuilt our entire frisbee collection, storage and shooting system.
