Bionic quadruped robot

Abstract

The invention relates to a bionic quadruped robot comprising four leg mechanisms connected with a trunk and a plurality of head-tail structure units, each leg mechanism provides six degrees of freedom, each head-tail structure unit provides two degrees of freedom, and the head-tail structure units are sequentially connected according to flexibility requirements to simulate connection of the neck and the tail with the trunk. On the basis of bionics, all parallel mechanisms are adopted for structural design, and compared with a series structure, higher bearing capacity is achieved, so that higher safety is achieved; through reasonable structural design, all driving pairs of the mechanical dinosaur are guaranteed to be moving pairs, and sufficient power and strength are guaranteed through hydraulic cylinder driving; the relative poses and sizes of the leg mechanisms and the head and tail structure units refer to the size of the dinosaur fossil recovery model, so that the posture of the dinosaur can be better simulated; the head and tail structure units of the mechanism pose can be selected and combined according to the required motion flexibility, so that the structure is simplified.

Description

technical field [0001] The invention relates to a technology in the field of robots, in particular to a dinosaur-based bionic quadruped robot. Background technique [0002] With the development of economy and society, people's living standards are constantly improving, and the demand for spiritual life is also increasing. It has become a world trend to apply science and technology to people's spiritual life. Dinosaurs are familiar creatures, and they are also prehistoric creatures that many people love and yearn for. Therefore, mechanical dinosaurs have great potential for development in the fields of theme parks, large-scale events, stage performances, and educational science. [0003] At present, the development of large-scale mechanical dinosaurs in China is slow. The models of mechanical dinosaurs do not have mobility or only part of the structure is movable, and they do not have the ability to walk autonomously; Australia is already in the leading position in this field...

AI Technical Summary

Problems solved by technology

In the market of large-scale mechanical dinosaurs, the current products have some common problems, the number of degrees of freedom of the whole machine is small, and the flexibility of the whole machine is not enough, which leads to the rigid sense of movement of the simulated dinosaurs; mechanical dinosaurs often need to use certain auxiliary equipment such as rails, brackets, etc. Brace movement, greatly reducing realism
