Nettet1. okt. 1992 · A new formulation of the inverse dynamics of the Delta robot is derived. It is referred to as a model “in the two spaces” since it requires the robot state variables both in joint space and in task space. This model is used in a computed torque based control scheme with a linear feedback in task space. Nettet1. jan. 2012 · Abstract. In the above joint space control schemes, it was assumed that the reference trajectory is available in terms of the time history of joint positions, velocities and accelerations. On the other hand, robot manipulator motions are typically specified in the task space in terms of the time history of end-effector position ...
