Meet Little Casper, a robot designed to help children suffering from cancer

A robot named "Little Casper" has been designed to help children in hospital suffering from cancer. It is currently being tested at this hospital in Lisbon. Little Casper is just not an ordinary robot. He was built to perceive the environment and to interact with it. Casper plays and talks; sophisticated sensors, art imaging devices and navigation systems allow him to autonomously move around, recognising young patients and avoiding obstacles.
