Mechanisms can be thought of as a system of elements that transmit motion in a particular pattern while a machine can be thought of as system elements that transmit motion and energy in a predictable way. Machines are often made up of a series of mechanisms that perform work. In reality there is not a clear cut line between mechanisms and machines. Kinematics is the study of motion without considering the forces involved and kinetics is the study of forces on systems in motion. In the real world these concepts are linked. By combining simple mechanisms complex machines can be designed. Moving elements can include linkages, cams, gears, belts and chains. Bicycles contain a relatively small number of moving elements while an automotive transmission contains a large number of moving elements.

There is no one definition for robots. According to the Encyclopedia Britannica a robot is “any automatically operated machine that replaces human effort, though it may not resemble human being in appearance or perform functions in a humanlike manner.” The term “robot” was first used by Karel Capek in his 1921 play, R.U.R (Rossum’s Universal Robots). The study of robots is call “robotics”, a term coined by the prolific science fiction writer, Isaac Asimov and first used in his short story, Liar published in 1941. These terms are used in both fact and fiction.
