My robot idea is a robot that assists disabled, or physically/mentally incapable people by doing jobs they can't do, such as vacuuming, carrying things, to something as simple as changing the TV channel. It gives these people a chance to live on there own without the need of constant help/supervision. The Bot will have arms to move/open things, a camera for navigation and face recognition(don't want to take the box to the wrong person!), as well as a strong sturdy base to carry stuff on. A relative of mine suffered an amputation at an old age and currently needs help 3 times a day, with almost constant supervision. This bot could help her get back and functioning like she used to!
