A novel direct-driven and portable exoskeleton robotic system for the hand is proposed. The system design is based on the multi-parametric optimisation procedure, which considers isotropy, dexterity and exertion of perpendicular forces on the finger phalanges. Actuators for the proposed device were selected based on results of experiments with users having different hand sizes. These experiments measured various parameters including average and maximum force exertion levels of a human hand. The experimental results were used to realise the mechanical design and to develop a prototype. The device can exert force levels (of 45 N) beyond any existing hand exoskeleton. Preliminary trials carried out on the fabricated prototype dictate efficacy and potential of the proposed system.
