The idea behind Fido Luggage, a product concept from architect Peter Yeadon, is a robotic suitcase that follows you around on its own without you having to pick it up even. Once the bag's owner slips on a watch-like controller, the suitcase is under remote control, able to follow both passively over a wireless link, and to obey voice commands. The bag's wheels are each independently controlled for smooth travel in any direction, and laser sensors help it navigate rough terrain and avoid running over small children.
