I actually don't have anything from our robot. I did store a robot at my house temporarily (between demos in the off season) and I did have a lot of raw materials (aluminum, steel, pvc pipe, ect.) stored in my garage laying under my Mustang when we lost our storage space but I brought all that stuff to our school by the time spring came and I wanted to get the Mustang out. I do have a lot of other stuff that was discarded from where I work like pnuematics and electrical. This comes in handy when I decorate for Halloween. I have a pnuematic cylinder with a 1 1/2" bore and a 6 foot stroke which is good for hiding behind the shrubs with a ghost attached to it. When the kids come up the sidewalk to the door all I have to do is fire the cylinder and the ghost pops up from behind the shrubs.
The cylinder was originally used on a pnuematically driven axis for a injection molding robot.
