Inverse and Forward Dynamic Analysis of Two Link Manipulator

Abstract

In the paper we show the possibilities of physical modeling in Matlab/SimMechanics on a simple mechanical model of two link manipulator. We deal with its direct and inverse dynamics. Considering direct problem we investigate mechanical movement of the robot under the action of given forces and moments. As regards the issue of inverse motion we identify forces which cause a prescribed motion of the effector. Both problems are solved using block diagrams in Simulink and SimMechanics. Results are presented graphically.
