Till now there have been robots who deliver mail and vacuum clean the floor, but their navigation has been controlled via pre-fed maps of the area's in which they work. This approach is difficult to programme domestic helps who have to encounter a terrain which is not constant. People place things here and there and the room map is not constant with use. Hense arises the need to programme the Robots with Sight. Efforts are being done in this quarter by trying to use a Web Camera to work as the sight for the Robot so that they can assist the elderly and those handicaped or sick.
More on this in later posts.
