How to draw a robot

The term robot originated in Czech "robota" meaning worker or porter who is tireless or bored. Robots are usually used for heavy, dangerous, repetitive and dirty jobs. Usually most industrial robots are used in the production field. The use of other robots includes toxic waste removal, underwater and aerospace exploration, mining, "search and rescue" jobs, and for mine search. Lately robots have begun to enter the consumer market in entertainment, and household appliances, such as vacuum cleaners, and lawn mowers.
