WebJan 2, 2024 · The task Jacobian defines a dual relation between motion and force quantities. The virtual work principle can be used to establish the link between task and joint space forces (13) where defines a mapping from a low- to high-dimensional space. WebWe also have an m DOF task ( m ≤ n ), for example, control of an end-effector, represented by the task-space configuration vector , and the task Jacobian J ( q ), as defined by the relations J ( q) = ∂ f /∂ q and . To control motion within the task space, we can compute a configuration velocity to realize some desired task velocity as follows,
