Grasping and lifting a coffee cup without spilling a drop. That’s no easy task for a machine, as first-year students of Mechanical Engineering discovered during their recent Click, Whack and Wallop final battle. Their challenge was to design and build a pneumatically-driven mechanical grabber, capable of holding a cup weighing up to 500 grams and lifting it 25 centimetres. The contents could be bronze, water or pasta, and it all had to stay in the cup. As well as a working prototype, each of the one hundred teams had to produce a website about its design.
