That was a result of shooting the balls with wheels that had tread ziptied to them. You'll notice that we did use multiple balls, and they were both torn up, one badly, one not so badly. We got rid of the zipties and it has not been nearly as bad since then. The chunks you saw hanging off the one ball were actually pieces of duct tape. The other one has some holes in the fabric, but that is all.
Also, the main purpose of this video was to showcase the power we were able to get. We have measured only 6 inches of arc from a linear path. We aren't expecting it to be the most accurate prototype shooter ever, as we aren't controlling speed in any way, just plugging the motors into a battery. We are expecting it to become more accurate as we use better bearings, wheels, add speed control, mount it to a sturdy frame, etc. We also weren't wasting much of our time with the teaser, as it was made outside of shop hours, took only 30 minutes, and the CAD design is already done. The only thing we can really do right now is prototype and wait for parts.
Finally, we are trying to avoid showing the shooter, as we don't want to give anything away yet regarding the other mechanisms of the robot
. As JesseK said, we wouldn't want to see our own designs used against us!
