Today, we learned how to work the multimeter, an instrument that allows us to measure the voltage of any AC/DC circuit. This will be invaluable when we are constructing our actual robot and measuring its wiring.
Mr. Dodson has also pointed out that the screws we were using on our frame are square-ended. Obviously, that won't work with many holes, and the inspectors frown on them. So we'd better remove those.
We've refined our original prototype, curling the brush/spike/protrusions to give them extra strength. After our bucket/paint-roller failure, it's heartening to have a prototype that works quite well! Walter and company are constructing a new prototype that will hopefully do the intended job of the bucket/paint-roller prototype, which is shooting the basketballs through compressing them between rolling objects (in this case, robot wheels).
