Embodiment Construction

[0029] The specific implementation manner of the robot finger device in the present invention will now be described in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, the robot finger device in the present invention is mainly composed of three parts, which are respectively a base 10, a first finger segment 20 and a second finger segment 30 arranged in sequence, and in the robot finger device, the first finger segment 20 and the second finger segment When the second finger section 30 moves, the base 10 remains fixed. Wherein, the first finger segment 20 is hinged on the base 10 through the proximal joint axis 40 , and the second finger segment 30 is hinged on the first finger segment 20 through the distal joint axis 50 . according to figure 1 The positional relationship expressed in , define the arrangement direction of the base 10, the first finger segment 20 and the second finger segment 30 as vertical, then the first finger segment 20 is pro...

Abstract

The invention relates to the technical field of a bionic robot, specifically relates to a robot finger device, which can solve the problems of small grabbing range and poor applicability of the robotfinger device in the prior art. The robot finger device comprises a base, a first finger segment hinged on the base around a proximal joint axis and a second finger segment hinged on the first fingersegment around a distal joint axis, wherein the second finger segment is fixed on a second finger segment connecting rod hinged with the distal joint axis; the arrangement direction of the base, the first finger segment and the second finger segment in an initial state is vertical; the first finger segment is provided with a guide sliding base which is guided to move along a direction crossing thevertical direction; the guide sliding base is hinged with the a connecting rod and a variable coupling connecting rod; the first finger segment is provided with a grabbing connecting rod, the grabbing connecting rod is provided with a grabbing end for grabbing articles and a variable coupling end hinged with the variable coupling connecting rod, the variable coupling connecting rod is positionedat one side of the grabbing connecting rod back to the grabbing direction of the robot finger device, and the hinge point of the grabbing connecting rod and the first finger segment is positioned between two ends of the grabbing connecting rod.

Description

technical field [0001] The invention relates to the technical field of bionic robots, in particular to a robot finger device. Background technique [0002] In the process of robot development, technicians regard anthropomorphic robot as the highest state of robot research. Similar to humans, most functions of anthropomorphic robots are realized through hand manipulation, and the design basis of hand mechanism is finger device, which is one of the key technologies of anthropomorphic robots. [0003] The main advantage of the advanced dexterous hand is that it can grasp objects flexibly and actively, and has good grasping stability. The disadvantage is that the dexterous hand cannot automatically adapt to the shape and size of the object when grasping the object. Sensing and control systems have high requirements, complex systems, high costs, low reliability, and require high-level technical personnel to operate, and the operating threshold is high. Underactuation technology...
