"WebThe entries in the Jacobian matrix are usually very easy to calculate. If the jth joint is a rotational joint with a single degree of freedom, the joint angle is a single scalar µj.Let pj be the position of the joint, and let vj be a unit vector pointing along the current axis of rotation for the joint. In this case, if angles are measured in radians with the direction " - Tojacobian
