It is mainly made of three joints, a gripper, two rectangular shaped links, a rotary table and a rectangular platform. The design of control systems is a multi-objective problem, so a two-degree-of-freedom (abbreviated as 2DOF) con-trol system naturally has advantages over a one-degree-of-freedom (abbreviated as 1DOF) control. You can typically identify the number of degrees of freedom by the number of actuators on the robot arm. That’s kind of the idea behind degrees of freedom in statistics. The number of degrees of freedom is equal to the total number of independent displacements or aspects of motion. Robotics involves design, construction, operation, and use of robots. References. Moving up and down is one degree of freedom, moving right and left. The arm, including the gripper, had six degrees of freedom and was driven by electric motors connected to the joints by belts.
