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. Witryna% We will first choose a particular joint angle configuration for the robot: q = [0.1 0.75 -2.25 0 .75 0] % and then compute the Jacobian in the world coordinate frame: J = … daniel wormald actor
