WitrynaThis video discusses robot singularities and Jacobians where the number of joints is not equal to the number of components of the end-effector twist or velocity, resulting in “tall” (“kinematically deficient”) and “fat” Jacobians. WitrynaFor a general open-chain robot with n joints, the space Jacobian is 6 by n. Each column of the space Jacobian is the spatial twist when that joint's velocity is 1 and the velocity at all other joints is zero. To derive the form of the space Jacobian, let's use a specific example: a 5R arm, whose joint angle are given by theta_1 through theta_5.
