Explain the relationship between the number of joints and the degrees of freedom in a robot arm.

Degree of Freedom (DoF) in robots is referred to as the number of free movements a robot can perform. A robot’s DoF is determined by its mechanical design and the number of joints. Each joint offers a single degree of freedom, enabling the robot to move or rotate along a particular axis. A robotic arm's degrees of freedom can be increased by integrating multiple joints.
