A three link RPP robotic arm is shown in figure 1 and its DH parameters table is provided in Table 1. Determine the jacobian matrix which correlates the joint velocities with task velocities Also determine the torque required for each motor to generate the force vector Fx,z [1.5 3.5]T . The robot is initially at rest: Table 1
