Aiming at the problem that the network time-delay in wireless network environment degraded the performance of the tele-operated construction robot system and even made the system unstable,the wireless network system and control system structure and fuzzy controller of the tele-operated construction robot system were designed.With the help of WAN emulator,the experimental re-searches of the position step response and sinusoidal trajectory tracking characteristics of the grabbing structure of robot under variable network time-delay were conducted in the wireless network environment.The results show that the fuzzy controller,as compared with the traditional PID controller,has better dynamic and steady state characteristics and better adaptability and robustness to the network time-delay.The research result has guiding significance for improving the performance of tele-operated construction robot system in the wireless network environment.
