Abstract:
A novel method to measure the mechanical characteristics of the Extravehicular activity spacesuit glove(EVA glove) joint by use of robot technology is proposed.A new exoskeleton manipulator based on planar four-bar parallelogram mechanism is developed.This manipulator that can exert forces in two directions has good stiffness and its joint can rotate about a fixed center.The length of phalange of manipulator can be regulated for adapting to gloves.Based on the manipulator special mechanical structure a mathematical model of the manipulator is given.Aiming at the characters of flexible joint of EVA glove,a two-degree-of-freedom finger modeling of EVA glove is put forward.A controller architecture is built.The controller kernel is a PCI card,which contains a high-speed float DSP processor.
