humanoid robots that have such fine motor control - quite thrilling! as long as they remember the 3 laws of robotics:
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
isaac asimov wrote these in 1942. they still seem pretty applicable to me in 2007. i think we are a long way from android rights issues. meanwhile, as long as we find viable renewable power sources for such mechanical devices, the idea that they may be able to help older people to be physically safe and cared for is very attractive.
