This paper presents a new design of exoskeleton for human locomotion system, based on a cam mechanism. Cam profile is determined by the main joints motion laws of the human locomotion system. Constructive solution adopted is validated by virtual simulation software package made by Adams software. The results obtained through virtual simulations consist in mass centres, displacements, velocities and accelerations of the exoskeleton kinematic elements.

The authors have developed a shoulder joint model considering RRR type serial manipulator. The servo motors are placed in such a way that they are dynamically balanced. For estimating the torques for each motor L-E method is employed. The joint architecture developed depicts circumduction, pronation and supination and abduction and adduction. Torque values are obtained both analytically and practically. Graphs are plotted and the results obtained are supportive to consider the joint for rehabilitation.

A study concerning the children locomotion system is presented through this research. The research aim is to obtain the motion laws developed by the children locomotion system’s articulations and connection forces which are produced in their structure in the walking activity. These parameters are useful for orthotic and prosthetic systems design for children with ages between 4-7 years. The study is based on an experimental analysis developed with ultra highspeed video equipment on 20 children and a dynamic analysis achieved on analytical way by using the results obtained from the experimental analysis. A new knee modular orthosis and a parameterized lower limb are designed through this research.
