The paper deals with the dynamic analysis of human arm, determination of shoulder and elbow torques considering isotonic and isokinetic exercise activities. Using Lagrangian-Euler method for dynamic equation of motions, code in MATLAB are developed which can be used to give torques encountered at shoulder and elbow joints for the respective trajectories obtained for different cases. Video tracking and motion capture techniques are used and clippings are analysed using NexGen Ergomaster tool. The results obtained for isokinetic flexion are in tune with those obtained by other researcher.

Application of Robotics in the field of medical has gained a strong footing apart from manufacturing industries, sheep-shearing, agriculture, nuclear power industries, fire-fighting, mining, underseas applications, outerspace and other application. In the present work Dynamic equation of motions of a robot arm are considered using Lagrangian-Euler formulation and programs in C, C++ and MATLAB are developed. The program encompasses the Torque, Centrifugal and Coriolis and Gravity force applied to the leg of a human being which is compared to robot manipulator. For the purpose of analysis cases of a human being lifting weight is considered. The results obtained by the program are compared with those obtained by some of the researcher
