Abstract

The invention discloses a five connecting rod parallel clamping self-adaption robot fingers device, and belongs to the technical field of robot hand. The five connecting rod parallel clamping self-adaption robot fingers device comprises a base seat, two finger segments, two joint shafts, a motor, a transmission mechanism, two connecting rods, a spring part and a limiting convex block. According tothe five connecting rod parallel clamping self-adaption robot finger device, the functions of parallel clamping and self-adaption grasping of two joint robot fingers are realized. According to the difference of the shape and position of an object, a second finger segment is moved in parallel to hold the object and is splayed to support the object, and a first finger segment and the second fingersegment are rotated in sequence to envelop the objects of different shapes and sizes. The five connecting rod parallel clamping self-adaption robot fingers device is large in capture range. The underactuated manner is adopted, and a motor is used to drive two joints without the need for using complex sensing and control system. The five connecting rod parallel clamping self-adaption robot fingersdevice is simple in structure, small in volume, low in manufacture and maintenance cost, and suitable for the robot hand.

Description

technical field [0001] The invention belongs to the technical field of robotic hands, and in particular relates to the structural design of a five-link flat clip self-adaptive robot finger device. Background technique [0002] As an important part of the robot, the robot hand is a hot and difficult point in robot research. The developed robot hands (industrial grippers, underactuated hands, dexterous hands and special hands, etc.) can complete specific tasks in many special environments with the help of robot sensing and control systems. [0003] The dexterous hand has more joint degrees of freedom and higher anthropomorphic dexterity, and can complete most human grasping, operation and sensing functions, but the demand for real-time sensing and control is high, the system is more complicated, and the cost is more expensive, which is not conducive to promotion application. The special hand is mainly a general term for various fingerless robot hands developed for specific o...
