Soft grasping technology of electron hydraulic servo manipulator

Robotpsilas soft grasping function relies on the fine-performance force sensor, position sensor and slip sensor. The micro-vibration measurement based slip sensor employs the elastomer and the photoelectric apparatus installed in the manipulator to transform the objectpsilas slide against the manipulator into an electronic signal to detect the slide at the moment of grasping. The objectpsilas slide against the manipulator causes the elastomerpsilas micro-vibration. Based the vibration, kinetics, illuminance and elasticity deformation theories, the linear relation between the acceleration of the slide and the differential of the output voltage of the photoelectric apparatus can be deduced, which will be used to establish the sliding degree determination mode. A fuzzy control strategy have been developed for soft grasping of electron hydraulic servo manipulator, which mimics the thinking modes of the human brain.
