Active double-mode rope-driven five-finger dexterous manipulator

Abstract

The invention relates to an active double-mode rope-driven five-finger dexterous manipulator. The manipulator comprises a palm assembly, a thumb assembly, an index finger assembly, a middle finger assembly, a ring finger assembly and a little finger assembly, wherein the thumb assembly, the index finger assembly, the middle finger assembly, the ring finger assembly and the little finger assembly are arranged on the palm assembly. The manipulator has the advantages that the structure is simple, the design is reasonable, and grabbing is flexible; the manipulator can grasp objects in a pluralityof ways through a thumb rotating motor; according to the manipulator, through two different driving modes, the problems that a manipulator is slow in object grabbling and the grabbing force of the manipulator is small are solved, the manipulator can grab an object quickly, and the generated grabbing force is large; and according to the manipulator, a four-bar mechanism is adopted, so that the number of finger driving motors is reduced under the condition that the basic daily life function of the manipulator is not affected, meanwhile, the complexity degree of the manipulator is reduced, then the manufacturing cost of the manipulator is reduced to a great extent, and the weight of the manipulator is correspondingly reduced at the same time, and therefore the manipulator has outstanding advantages in terms of the manufacturing cost and the quality and the size of the manipulator.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an active dual-mode rope-driven five-finger dexterous manipulator. Background technique [0002] In recent years, with the rapid development of the economy, robots have also been developed rapidly and are widely used in various fields. The manipulator is the final actuator of the robot's work, and its performance directly determines the working ability of the robot. Similar to humans, the development of manipulators with high versatility and dexterity is necessary. [0003] At present, domestic institutions including Beihang University, Tsinghua University, Harbin Institute of Technology and the Institute of Automation of the Chinese Academy of Sciences have some technical research on dexterous manipulators. However, its volume is large, its weight is high, it is not fully driven by five fingers, and its dexterity is insufficient. In foreign countries, although manipulators incl...

AI Technical Summary

Problems solved by technology

However, its volume is large, its weight is high, it is not fully driven by five fingers, and its dexterity is insufficient.

In foreign countries, although manipulators including shadowhand have high dexterity, their structures are complicated, their production costs are high, and the energy density of the driving device is much lower than that of human hands. There is a large gap between the strength of the force and the human hand, and the manufacturing cost is high, which increases the obstacles for the practical application of the bionic robot hand
