Web17 de set. de 2013 · The idea behind operational space control is to abstract away from the generalized coordinates of the system and plan a trajectory in a coordinate system that is directly relevant to the task that we wish to perform. Going back to the common end-effector position control situation, we would like to operate our arm in 3D Cartesian space. WebOperational space control (OSC) is one of the most elegant approaches to task control for complex, redundant robots. Its potential for dynamically consistent control, compliant control, force control, and hierarchical control has not been exhausted to date. Applications of OSC range from end-effector control of manipulators up to balancing and ...
