Varieties of Robots

Engineering and science have developed so far that they have even led to the development of machine humans that work on instructions and external sources of power for functioning. These machines are known as robots and are known for their artificial intelligence. Robots are usually programmed by a set of instructions to carry out certain defined activities. The robots are programmed just like computers but can walk around and lift things and do manual work also like human beings. There are several different varieties of robots that have been developed in today’s world and we would discuss them briefly here.
