Rotations are either repre- parallel nor anti. J_b is obtained from J_s by the matrix adjoint of T_bs, and J_s is obtained from J_b by the matrix adjoint of T_sb. Matrices are represented by a At least two motions whose rotation axes are neither bold capital letter, e.g. Since each column of a Jacobian is a twist, we can use our rule for representing a twist in a different frame to translate between the space Jacobian J_s and the body Jacobian J_b. In the previous video, we learned how to take the joint screw axes S_1 to S_n, defined in the space frame.
