A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connect by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be consider to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand. However, the term “robotic hand” as a synonym of the robotic arm is often proscribed.
