Experts from four universities deliver robots to four different families around Britain. Watching the robots' every move are psychologist Dr Caroline Jay and robotics specialist Professor Jonathan Rossiter. They want to see if the robots can complete their tasks, have humans bond with them and how they function outside of the lab and in the real world. In Blackburn, single mum Amanda and her six children take delivery of the TutorBot. It has been programmed to help her son Isaac, who has a rare form of dwarfism and a learning delay. For the next two weeks, it is going to try to help Isaac improve his speech. In Plymouth, the FitBot has been programmed to keep the Rocket family in shape. Over the next month, Plymouth University want to see if it can become a credible fitness and nutrition expert.
