A Study of Flexible Force Control Method on Robotic Assembly for Spacecraft Zhang Lijian *,Hu Ruiqin, Yi Wangmin, Fu Hao, Tang Laiying Beijing Institute of Spacecraft Environment Engineering, Beijing 100094, China E-mail: zljcast@163.com Keywords: Flexible Force Control; Spacecraft; Robotic Assembly Abstract: For complex spacecraft assembly conditions, how to play effective and flexible robotic characteristics, and improve production efficiency, is the problem needed to solve.this paper presents a flexible force control method on robotic assembly: a 6-axis force/torque sensor is mounted between tools and the end of robots, the operator operates the load by hands directly, and the system can obtain the force/torque information caused by operator’s hands through gravity compensation algorithm, then the force/torque information is used as input parameters to control the robots moving with the hands.
the operator can control with a small force to adjust and pose the large workpiece.the operator can follow the daily habit forming operation of the object,it is more intuitively to adjustment the pose at the end of robots and avoid the mistakes.this method combined with robots's stable and reliable with high precision and the operate flexibility of human observation together,more suitable for complex spacecraft assembly conditions. 2 Flexible force control theory Flexible force control theory of robots: put a ‘6-axis force/torque sensor’ between end effector and the end of robots,it is the key feedback components to achieve flexible force control on robots.‘6-axis force/torque sensor’ is the sensor that enable to measure any force system about The three dimensional orthogonal force （Fx，Fy，Fz）and three-dimensional perpendicular torque（Mx，My，Mz）[6].In the flexible force control of robots, 6-axis force/torque sensor is for sensing informations on the role of forces and moments.
