Algebraic approach to the stiffness model reduction for manipulators with double encoders

Abstract

The paper is focused on the problem of the stiffness model estimation that could be used in combination with double encoders for the detection of the compliance errors and applied forces. Algebraic approach is proposed based on knowledge of link stiffness parameters and kinematics of the robot. The application of this technique is demonstrated in the example of a 3-link manipulator.
