Robotic wheelchair

Here is a wheelchair robot that can serve the elderly, disabled, or handicapped. The innovation in this type of technology is that the chair supports you in all your movements. For example, you lean forward and it goes forward. You turn to the right and the chair follows. The sensors on the backrest and seat detect center of gravity movements. The person did not even need to use his hands to communicate the instructions. The robot is also equipped with a video camera capable of recognizing certain gestures from people facing it and going to meet them. It also helps defining pre-established paths for moving indoors. This model was displayed at the 2009 International Robot Exhibition in Japan. http://www.youtube.com/watch?v=4H8eMlaCN4w
