Its not really about the Robot. It is about having something to demonstrate that showcases different engineering process brought together to work towards a common goal. In this case it consisted of an Human Machine Interface Touch screen, a Programmable Logic Controller, A robot manipulator arm, a tube that you could drop a big steel ball bearing down and a home made sweet dispenser. If you could successfully control the robot via the touch screen, pick up the ball and drop it down the funnel into the tube it would make a switch which in turn would eject a sweet out for your efforts. It kind of showcased the sorts of things we do but in a fun interactive way. It was always the most popular demo we ever used on open days and school visits. Whats not to love technology and free chocolate!!!
