Abstract

The invention discloses a flexible three-finger clamp holder having a touch sensing function. The touch force distribution situations of the parts, in contact with a clamped object, of the fingers are obtained in real time through touch sensors attached to flexible claws and are fed back to a control system, and the control system controls a motor to drive grabbing strength of the flexible claws. The flexible three-finger clamp holder adopting the structure has the touch sensing function, can exert different clamping forces according to the specific characteristics of the object and does not damage the object. Due to the fact that the flexible claws are made from an elastic flexible material, the three fingers can product a large elastic deformation during object clamping, accordingly stronger attachment is formed, it can be ensured that the object does not fall or slip and is reliable to clamp, the flexible three-finger clamp holder is simple in structure and can serve as a terminal executor to be widely applied to various robots.

Description

technical field [0001] The invention relates to the technical field of mechatronics of robot end effectors, in particular to a compliant three-finger gripper with tactile sensing function. Background technique [0002] At present, the application of robots in intelligent manufacturing, home services and other fields is becoming more and more common. The development of the tactile perception function of the robot end effector is an important way to improve the intelligence of the robot. In more and more applications, robotic manipulators need to grip or grasp unknown objects. How to plan correct operation actions according to the characteristics of objects, such as softness and hardness, surface texture, spatial shape, etc., to ensure that the manipulated objects are not Dropping, not slipping, and not being damaged is a current technological trend. Robot end effectors generally use two structures to manipulate objects. One is the "dexterous hand" mechanism that realizes th...
