The pressure sensor calibration device provided by the invention is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of pressure sensor calibration, in particular to a pressure sensor calibration device and a calibration method. Background technique [0002] As the terminal perception and grasping tool of intelligent robots, the dexterous hand has high dexterity, versatility and adaptability, and can complete various grasping and manipulation tasks. It is widely used in dangerous environment detection, outer space exploration, Logistics handling, industrial assembly, rehabilitation medicine, intelligent manufacturing and agricultural picking and other fields. [0003] In the grasping operation of the dexterous hand, it is necessary not only to avoid the object being grasped from slipping due to too small grasping force, but also to prevent damage to the grasped object due to excessive grasping force. Steady grasping of objects. To be able to achieve minimum force grasping, the dexterous hand must have grasping force perc...
