What is a degree of freedom in the context of kinematics?
Degrees of Freedom:- The minimum number of independent joint variables in a mechanism that must be specified in order to completely define the mechanism's configuration.
For a simple mechanism, the degree of freedom (F) is given by Grubler’s criterion:
F = 3 (n − 1) − 2j − h
Where, j = number of revolute joints, n = number of links, h = number of higher pairs
