Problems solved by technology

The device can realize compound under-actuated grasping. The disadvantage is that due to the use of a single motor drive, it can neither achieve a faster grasping speed nor provide a strong grasping force, and the mechanism is complicated, and the number of spring parts is too large. The contradiction between the coupling and the coupling transmission mechanism and the adaptive transmission mechanism often makes the deformation of multiple springs larger, resulting in excessive and unnecessary energy loss

Abstract

A connecting rod type synergy drive robot finger belongs to the technical field of the robot hands. The connecting rod type synergy drive robot finger comprehensively realizes the effect of synergy driving of fingers with two motors matched with each other by employing two lead screw motors, a screw drive force-amplifier, a connecting rod transmission mechanism, an overrun clutch and a spring; a finger device is high in grabbing speed, and great in grabbing force and accurate in grabbing action; and simultaneously, the finger device is freely switched among major grabbing modes and suitable for being used as the finger parts of the hands of the ingenious robot.

Description

technical field [0001] The invention belongs to the technical field of robot hands, and in particular relates to a structural design of a link-type cooperatively driven robot finger device. Background technique [0002] The hand is a very important organ for humans. In the field of humanoid robots, it is of great significance to enhance the function of the robot hand. On the one hand, the grip strength of the robot hand can be strengthened through the transmission mechanism with a large reduction ratio, but it will slow down the grip speed of the robot hand and affect its dexterity; Will have a negative impact on its grip strength. At the same time, the robot hand requires a small size, so it is difficult to use a large and powerful motor. There are still many technical problems in this field. [0003] The so-called cooperatively driven robot finger device refers to a robot finger device in which at least one motor drives two or more joints, and at least one joint can be ...
