Solution
The Degree of Freedom (DOF) in robotics is defined as the minimum number of parameters/variables/coordinates needed to fully describe a system. This essentially means the number of independent ways a robot can move. For example, a robot arm might be able to move up and down (one degree of freedom), left and right (a second degree of freedom), and forward and backward (a third degree of freedom). Each joint or point of flexibility in a robot contributes to its degrees of freedom.
