Supershifters and Stackerbox's

[FIXIT]

It is very important to have the back-up battery fully charged. During a recent presentation, our robot decided to veer left while we were shifting into high gear and nearly took out a display case. Apparently there was enough power to shift one side only. An option might be to use the pneumatic system.

We had a slight gear misalignment (less that .01") inside one of our supershifters, so every rotation we'd hear one of the teeth hitting something. We slightly beveled that particular gear and haven't had a single problem with anything since. We're stoked.

We have over half of our allowable robot budget committed to the four SuperShifters that are going on the robot. We were worried a little about that, but actually more concerned about the 4.7 pounds per shifter that had to fit within the weight limits. But as Andy has noted, the SuperShifters have a LOT of room for weight removal. We have already carved a pound out of each one without even really trying, just by lightening the spacer block and large drive gears, and carving down the servo mounting block (since we are going with the pneumatic option). And there is still some more that can be done to get them even lighter. We have torn them down and rebuilt them probably two dozen times already, and they go together without a hitch. When they are fired up and running, all I can say is - these things are sweet!
