Japanese Develop a Robot Guide Dog

The Japanese company NSK has developed a guide dog that uses a Microsoft Kinect sensor to visualize the world around it and lead its owner out of danger. The dog glides around on four legs that have wheels attached to them instead of feet, and when it senses an obstacle it begins to climb. Using its hinged legs, the pooch climbs up and down stairs — albeit very slowly — with its charge following safely behind guided by a handle attached to the back of the dog.
