Robotic arm

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 connected by joints allowing either rotational motion or translational (linear) displacement. The links of the manipulator can be considered 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.
