The word biomechatronics is made up of biology, mechanics, and electronics. The field of biomechatronics is part of the larger realms of robotics and artificial intelligence (AI). Specifically, biomechatronics involves electronic and mechanical devices that duplicate human body parts and their functions. Biomechatronics has received more attention in Japan than in the United States. In Japan, some robot researchers attack their problems with religious zeal. Not only would Japanese robotics engineers like to build robots that can do all the things people can do, but some want their robots to look like people, too. The ultimate biomechatronic device is an android. Scientists generally agree that an intelligent android will not be developed for many years.
