Conveyor Belt/ Linear thing/ L.E. plan

We made a conveyor and a linear moving thing.  Me and Matt were working on the conveyor belt while Nick and Matt was working on the linear moving thing.  There was little difficulty while making them.  We just had to make sure everything fit and all that.  One of our motors did break though and we need to get it replaced.  For our Luke-Ericsson device we are going to be using the conveyor belt and linear thing.  We will also be using some of our large C. channels to have the tennis ball move from one thing to another and our debating whether to also make a catapult or a claw to finish it.  We will also be adding a few things in between but are not positive what that will be.
