title: [A robot measurement system for spacesuit joint torque].
abstract: OBJECTIVE
  To measure the joint torque of spacesuit so as to evaluate its dynamic force/torque performance.
  
  
  METHODS
  A method for measuring the spacesuit joint torque by use of robot technology was proposed in this paper. The design of the measuring strategy and measuring robot was put forward and a mathematical model of the system was given. Then the working space of the robot was analyzed.
  
  
  RESULTS
  The robot designed is light, compact, easy to operate, and has a large working space. Experimental results demonstrated the effectiveness of the measuring principle and the reliability of the measuring system.
  
  
  CONCLUSIONS
  The system can satisfy the requirements of the spacesuit joint torque measurement.
