According to the analysis of dynamic characteristic,the force transmission characteristics,of manipulatorsare studied.

Based on an analysis of the kinematic performance of the robot manipulator in a given direction, the concept of direction dexterity of manipulators is defined and some indices for measuring the dexterity of manipulators in a given direction are proposed.

According to the relational equation between the generalized force on the end-effector and the joint force of the manipulator derived, two indices for measuring the force-transmission dexterity, one for the absolute and the other for the realtive dexterity, are defined by two indices for the generalized and relative depende.
