A robotic tendon is modeled and the stiffness of the spring is tuned so that the spring power reduces the peak motor power and energy required for ankle gait. When determining stiffness from gait literature, it is usually assumed that one side of the spring is fixed. We assume that the spring is translating to derive a second method to calculate stiffness. By choosing a tuned spring based on a “dynamic stiffness”, the motor velocity was shown to be constant during the loading phase of ankle gait. We simulated this system and showed that energy was reduced and peak power was dramatically reduced. The constant velocity controller was implemented on a powered ankle foot orthosis and test data was correlated with the simulation.

Mechatronics is at present a dominating concept of designing machines and devices of various kinds. High speeds of data acquisition and processing achieved by means of microprocessor controllers used in such systems, as well as high dynamics of the actuators applied, make it possible to employ mechatronic devices in quite new fields. This refers to the medical domain as well, and wearable robots are one of the most spectacular examples. They are personoriented robots that can be defined as devices worn by human operators, whether to enhance the function of a limb or to replace it completely. The authors work on an orthotic robot for disabled people suffering from paresis of lower limbs. In the paper, there is proposed a functional structure of such device as well as review of similar systems under development around the world.

Robotic exoskeleton systems are one of the highly active areas in recent robotic research. These systems have been developed significantly to be used for the human power augmentation, robotic rehabilitation, human power assist, and haptic interaction in virtual reality. Unlike the robots used in industry, the robotic exoskeleton systems should be designed with special consideration since they directly interact with human user. In the mechanical design of these systems, movable ranges, safety, comfort wearing, low inertia, and adaptability should be especially considered. Controllability, responsiveness, flexible and smooth motion generation, and safety should especially be considered in the controllers of exoskeleton systems. Furthermore, the controller should generate the motions in accordance with the human motion intention. This paper briefly reviews the upper extremity robotic exoskeleton systems. In the short review, it is focused to identify the brief history, basic concept, challenges, and future development of the robotic exoskeleton systems. Furthermore, key technologies of upper extremity exoskeleton systems are reviewed by taking state-of-the-art robot as examples.
