Mechanical Engineering postgraduate students Edward Sells and Paul Riggs will be appearing on the Gadget Show on Saturday 28 March at 10.40am on Channel 5.
As part of a challenge set by Vic Reeves, they helped Gadget Show presenter Ortis Deley build a shopping trolley, designed by Vic, that uses infra red sensors to follow you around the store.
Vic and Ortis tested the invention in a car park before putting it through its paces in a supermarket.
