Seeings as it is getting to crunch time and our parts are really starting to all come together. I felt we should post a picture of our hopper which is arguably our second most critical module. The hopper is what goes into the slot after our arm has cleared out all the ping pong balls and picks up the heavier balls. Our hopper in constructed out of al square stock cut to be Al angle stock on the band saw. Then using sqaure wood pieces we made a hopper with a rubberband at the bottom which will deform as it is pressed onto a ball. Then the squash balls will be trapped in the hopper and a planetary motor on the rack will raise the hopper out of the slot. I will post more picture with the rest of our machine in the next few days.
