Military, Cleaning, Space Robots
can any one tell me the types of robots and their purpose.
No it is not necessary that all robots have arms and legs. Some robots have only arms and some have legs and some have wheels for their mobility. Basically it depends on the requirements as the requirements dictate how we design our robots. For example in automobile industries robots are used only for welding purposes or in paintshop. These types of robots have only arms not legs.
There are literally hundreds of types of submarine robots. All major countries of the world develop them.

The market for toy robots is subjective to numerous things including what movies are popular, the types of toy robots being marketed and other uncertain factors. Though it is impossible to say whether or not the market for these toys will develop further, there will probably always be some toy robots available.
