Tickle, the robot masseur

How about a robot to massage and relax you? This little autonomous robot masseur called Tickle should please fans of relaxing Swedish massages. It wanders around on the back with its nubbed rubber caterpillar tracks and when it senses it's going to fall (near a slope) it pivots and stays on the person. An original idea. You just can't be too ticklish :-) http://www.youtube.com/watch?v=nxEhndMS0Sk
