love to make a video for you guys but i replaced the batteries so the programs gone and my ir tower isnt working so i cant download a new one.. i just bought a new tower so once i get that and download it ill try to get a video of it.
the pneumatics and the stuff you see down the center of the base is just a 'fun' thing i put on just for the fun of it. its a rubberband launcher
see the old motor near the top of the photo? that (geared down with a clutch to prevent killing the structure and chain to gear it down more) connects to an axle which is linked to an arm that lifts the whole "barrel" up to shoot farther and also when it reaches full height it releases a pneumatic switch to push the two small cylinders which allow the rubber band holder to unlock and shoot the rubber band. the few springs up front (the way the arrows are pointing) are there to give the rubber band more push (or pull) to release it at a faster velocity....or so i think...theoretically...
this rubber band shooter mechanism is quite accurate considering i finished it in about half an hour. shooting rubber bands across the room, i seem to be able to hit a water bottle at least once every 5 shots. and that distance is about 3 and a half meters. hehe.
