Industrial robots are defined by the characteristics of their control systems, manipulator or arm geometry, modes of operation etc.
The term degree of freedom as applied to a robot indicates the number of its axes, an important indicator of a robot's capability. Limited sequence robots have two or three axes only while unlimited sequence robots typically have five or six-axes to perform more complex tasks.
The basic manipulator arm might have only three axes:
Arm sweep: It provides anti-clockwise and clockwise rotation about the vertical axis.
Shoulder swivel: It provides the arm to pitch up and down about a horizontal shoulder axis.
Elbow extension: It provides the arm to pitch up and down about a horizontal elbow axis.
