This article defines a local measure of failure tolerance based on the worst-case dexterity following a locked joint failure.}, abstract={Optimal values of this measure are identified and related to the required structure of a Jacobian matrix. It is shown that it is trivial to derive manipulator configurations that correspond to the desired Jacobians with the single exception of a manipulator with seven rotational joints that is required to perform tasks which require fully general linear and rotational velocities of the end effector.}, type={artykuł}, title={On the existence of an optimally failure tolerant 7R manipulator Jacobian}, keywords={sterowanie, sterowanie-teoria, sztuczna inteligencja, matematyka stosowana, informatyka}, }
