Demo 3 is similar to Demo 2 but a vehicle has been added to move blocks into the reach of the cranebot.  Both robots are controlled through Joystick control and uses web cams to that feed a stream of images using UDP and OpenCV to the controllers computer to orient them in the working space.

A few changes to the crane were the addition of a new piece that reroutes the wires along with straighten out the rack piece.  Also the claw was switched from a velocity control to a position control.

There were a few problems with the wireless connection in that it didn’t work well in the room this was ran in along with an unknown reason of burning out 3 battery chargers before the final run.
