Objective:
To measure the joint torque of spacesuit so as to evaluate its dynamic force/torque performance.
Method:
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.
Result:
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.
Conclusion:
The system can satisfy the requirements of the spacesuit joint torque measurement.
