Abstract

The invention relates to a bionic robot dog with a flexible structure; the bionic robot dog comprises a body frame, a flexible back, four legs, a head, a neck, a tail and a driving device; the four legs comprise thighs, shanks and feet; the top ends of the thighs of the four legs are respectively connected with two sides of a front frame and a rear frame; the hinge connection is utilized for the bottom end of the neck and the front end of the front frame, for the bottom end of each thigh and the top end of the corresponding shank and for the bottom end of each shank and the corresponding foot; the head is connected with the top end of the neck; the top end of the tail is connected with the rear end of the rear frame; two ends of the flexible back are respectively connected to the rear end of the front frame and the front end of the rear frame; the driving device comprises a plurality of groups of motors and transmission structures; the motors drive the thighs, the shanks, the feet, the head, the neck and the tail to finish certain actions by means of the transmission structures; the flexible back is of a flexible connector; and four legs are provided with flexible parts. The bionic robot dog with the flexible structure has various motion ways; and the flexible structure is capable of absorbing impact, delivering energy and improving motion flexibility.

Description

technical field [0001] The invention relates to a bionic machine, in particular to a bionic robot dog with a flexible structure. Background technique [0002] Dogs have strong athletic ability and interactive ability. Using dogs as prototypes, the development of small, lightweight and adaptable bionic robot dogs is not only of great significance to the development of robotics, but also has broad applications and development as a smart home. prospect. The four-legged robot dog "Aibo" produced by Japan's Sony Corporation earlier is a representative of robots for home life. Aibo has a strong human-computer interaction capability and a growth system, but it only has a bionic appearance, and its movement ability is not strong. [0003] The main moving parts of the robot dog are the legs and the spine which assists the movement. Applying structures such as ligaments and tendons to the bionic structure design of the legs and spine will improve the performance of the robot dog an...
