and System, Beijing, China
Research Assistant / Project Leader
The main goal of this project was to control a robot arm on a spaceship. Since there was long transmission delay of the control signals from the ground station to the spaceship, the controller could not see the real-time movement of the robot arm and could not properly control it. Therefore, we had to build a system to simulate robot arm movement and compute error compensation to adjust the simulated robot arm when receiving feedback information from the real robot arm. The theoretical work was done by several researchers at State Key Laboratory of Artificial Intelligence at Tsinghua University. I led a team with 15 students, mostly Ph.D. and Master students, to develop the system. I joined the work of system design, robot model creation, control algorithm design and analysis, 3-D path planning and collision detection, and system administration (a SGI ONYX graphic workstation and Sun workstations). The system had been certified by the National Industrial Association in Science and Technology of China. I also designed and developed a 2-D path planning system by using Genetic Algorithm
