A novel exoskeleton multi-fingers robot to measure the Extravehicular activity spacesuit glove (EVA glove) joint’s mechanical characteristics is presented. The exoskeleton finger based on planar four-bar parallelogram mechanism has enough stiffness and can exert forces in two directions
finger joint can rotate about a fixed center that avoid disturbance between finger and glove. The length of phalange of manipulator can be regulated for adapting to gloves. According to finger special mechanical structure
a kinematic model is given. Based on the dynamical model of exoskeleton robot finger the μ-synthesis robust controller is presented. System uncertainties are analyzed. The load dynamics are represented by a feedback uncertainty model. The proper control model is built. The trajectory tracking experimental results show that μ-controller can suppress the influence of disturbances and control system has robust stability and robust performance. The measurement results demonstrate that the robot system works well and reliable
