Wearable robots are robots which are used for rehabilitation or augmentation by human. Recently, there has been an increasing interest in the development of wearable devices to assist elderly as well as patients, soldiers and many other persons for movement assistance and power augmentation. On the other hand, a realization of wearable robot which has the same degree of freedom of a human is not easy from considerations about a size and weight of device. This study is about a lower limb assist robot that consist of just an actuator on each of legs. In this paper after a brief review on wearable robots and their applications, a suitable design of robot which is named RoboWalk presented with inspiring from Honda weight compensation system. In the following kinematics and dynamics modeling of system presents with using of denavit-hartenberg parameters and validates with ADAMS software results. Results with high accuracy has been achieved. It’s necessary to evaluate main foundation of design of robot which is an assistant force in the direction of foot reaction force that has been achieved with the accuracy of 0.02 radians. finally effect of change in user’s weight, position of center of mass and friction of walking assistant robot component is examined in this study.
