Problems solved by technology

The currently used bionic hand devices mostly use pull wire devices or artificial muscles to control the fingers, which are easy to damage and need to arrange driving devices in the space other than the fingers. The cost of artificial muscles is generally relatively high, and the control is relatively complicated

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The present invention is a bionic manipulator driven by a full linear driver, such as figure 1 As shown, the bionic manipulator includes a bionic palm 1 and a thumb 2, and also includes any one or more of the index finger 3, middle finger 4, ring finger 5 and little finger 6, and the thumb 2, index finger 3, middle finger 4, ring finger 5 and The little fingers 6 are all hinged on the palm 1 . Such as figure 2 Shown is a bionic manipulator with only thumb 2 and little finger 6 installed. The structures of the index finger 3, middle finger 4, ring finger 5 and little finger 6 are the same, and their own size and their connection positions on the palm 1 are set in imitation of human hands.

[0028] The structure of the thumb 2 is as follows figure 2 As shown, it includes a proximal thumb 201, a distal thumb 202, a linear actuator A203, and a linear actuato...

Abstract

The invention discloses a full-linear actuator driven bionic mechanical hand and belongs to the technical field of robots. The bionic mechanical hand comprises a bionic palm and a thumb, and further comprises any one or more of an index finger, a middle finger, a ring finger and a little finger. The index finger, the middle finger, the ring finger and the little finger are of the same structure and are all hinged to the palm. The thumb is provided with two knuckles. The index finger, the middle finger, the ring finger and the little finger are each provided with three knuckles. According to the full-linear actuator driven bionic mechanical hand, linear actuators are directly arranged in the positions of the knuckles of the fingers without using any pull wires and pull wire accessory devices and do not need to occupy extra space outside the mechanical hand for arrangement. The full-linear actuator driven bionic mechanical hand is visual, easy and convenient to control and convenient to maintain and replace. Pressure sensors are arranged at the fingertips of the fingers and used for detecting contact force borne by the fingers. The full-linear actuator driven bionic mechanical hand can simulate basic movements of a human hand.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a bionic manipulator driven by a full linear driver, which is a mechanical device capable of simulating the movement of a human hand. Background technique [0002] Today's robot technology is developing rapidly, and it has gradually expanded from industrial robotic arm devices to household robots. In actual operation, it is not enough to only simulate the movement of the arm, and it is also necessary to simulate the movement of the human hand to perform operations such as grasping. The currently used bionic hand devices mostly use pull wire devices or artificial muscles to control the fingers, which are easy to damage and need to arrange driving devices in the space other than the fingers. The cost of artificial muscles is generally relatively high, and the control is relatively complicated. Contents of the invention [0003] Aiming at the deficiencies of the existing technology...
