When speaking of the degrees of freedom, it refers to the movement of the pieces in a three-dimensional space, such as the translation in the three perpendicular axes (forward, backward, left, right, up, and down), the rotation in cylindrical pieces or the combination of previous movements.

Abstract
This work describes the direct and inverse kinematics mathematical framework, the development procedure, and data communications interface for the implementation of an augmented reality version of a six degrees of freedom (6-DOF) cobot (collaborative robot) under the Unity platform. The kinematic equations for the inverse kinematic control of the Techman® cobot are presented. The procedure to achieve communication between the virtual robot and the physical robot is described, that is, the communication link from the TM5-900 robot with the application in Unity. A safe environment was created to manipulate the collaborative robot and to avoid collisions to validate the applicability of the augmented reality functionality. The virtual twin with its enhanced visualization based on augmented reality can also run-on mobile devices either locally or remotely accessed. The developed platform has diverse potential applications and in particular is suitable for engineering education and training in robotics.
