Importance of jacobian in robotics

WitrynaThe matrix J is called the jacobian of the map; that is, the jacobian is the matrix of partial derivatives. In this case:- ... Perhaps the most important use for jacobians is for relating the joint velocities to the link ... The movements that can be performed by robots are very general; however, for WitrynaJacobian and singularity analysis are important tools for designing and controlling robot manipulators, especially in complex tasks that require precision, speed, and dexterity.
