Abstract:In the nuclear power station, nuclear facilities and strong radiation risk environment, technology of remote control demolition robot is widely used. The working of robot was monitored in far off distance, regulated and operated through the remote cameras, to complete demolition, selecting, remove and transport toxic nuclear waste, and some other high intensity-risk labor. The hydraulic controlled demolition robot had smaller volume, more force and high mobility, which could be deployed more effectively and rapidly in dangerous environment. Aimed at the requirement of application in radiation environment, the system of demolition robot controlled by hydraulic was developed, and its geometric structural characteristics and hydraulic control system were analyzed in detail. At last, a co-simulation is carried out between ADAMS and EASY5, verifying effectiveness of hydraulic control system.
