AI Technical Summary

Problems solved by technology

[0003] Through the analysis of the current situation at home and abroad, there are many studies on two-legged, four-legged and six-legged robots, but relatively few studies on single-legged and eight-legged robots. Due to the large number of legs of eight-legged robots, the types of gaits And more, its ability to adapt to the terrain will be greatly improved, but the complexity of its coordination and control will also be greatly increased
[0004] The current bionic robot crab has disadvantages such as low walking efficiency, difficulty in walking in a straight line, and excessive transmission joint clearance.

Embodiment Construction

[0014] The new multi-legged bionic robot crab has higher load-carrying capacity and motion performance, and the setting of the ratio of the leg joints of the walking legs makes it closer to the bionic object. The designed elastically driven joint effectively reduces the impact force on the joint when walking dynamically in an unstructured environment, and realizes structural bionics.

[0015] 1. The specific implementation of the modular drive joint.

[0016] Aiming at the shortcomings of low transmission efficiency and large transmission gap of the mechanical crab driving joint, a modular driving joint is designed.

[0017] Each modular transmission joint is output by a DC servo motor through a worm gear reduction mechanism. The adjustable end cover structure at the front end of the gearbox solves the problem of excessive axial force of the worm gear on the motor shaft and effectively protects the motor.

[0018] 2. The specific embodiment of the single walking foot structu...

Abstract

The invention discloses a novel multi-legged bionic machine crab. The novel multi-legged bionic machine crab is characterized in that joints adopt modular pressure spring limiting type elastic driving joints; mechanical legs adopt single-walking leg structures; the legs are arranged in parallel in two rows; and the novel multi-legged bionic machine crab effectively solves such defects as low walking efficiency, troublesome linear walking and excessive gaps among transmission joints.

Description

technical field [0001] The invention relates to the field of robot bionics, and is a mechatronic device integrating machinery, electronics, computer, control technology and bionics. Background technique [0002] With the changes in the international political situation and the form of war, a large number of unmanned combat weapons are needed in the fields of military reconnaissance, battlefield attack, anti-terrorism and explosion protection; as human beings explore space, the construction of space stations, emergency rescue and disaster relief, etc. are not suitable for human beings. With the increase of tasks, there is an increasing need for corresponding robots that can replace humans to perform tasks. At the same time, new requirements and tasks also put forward higher requirements for the performance of robots. By studying the characteristics of these operating environments, we can find that the irregular and uneven unstructured environment has become a common feature o...
