Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] see figure 1 As shown, a kind of snake-shaped bionic robot based on flexible telescopic joints of the present invention comprises a robot snake head 1, a first snake body 2, a second snake body 3 and a robot snake tail 4, and the robot snake head 1 adopts the snake head joint and the first snake body 2 are connected, the first snake body 2 is connected with the second snake body 3 by snake body joints, and the second snake body 3 is connected with the machine snake tail 4 by snake tail joints.

[0017] see figure 1 As shown, the snake head joint includes a snake head joint spring A51 and a snake head joint spring B52. The snake head joint spring A51 and the snake head joint spring B52 are two types of different springs, one is a helical compression spring and the other is a torsion spring.

[0018] see figure 1 As shown, the...

Abstract

The invention discloses a snakelike bionic robot based on flexible stretching-retracting joints and belongs to the field of bionic robots. The snakelike bionic robot comprises a robot snake head, a first snake body, a second snake body and a robot snake tail; the robot snake head is connected with the first snake body through the snake head joint; the first snake body is connected with the secondsnake body through the snake body joint; the second snake body is connected with the robot snake tail through the snake tail joint; a first motor is mounted at the front end of the first snake body; asecond motor is mounted at the front end of the second snake body; and a steering motor or a stepping motor can be selected as the first motor or the second motor, and the first motor and the secondmotor rotate synchronously and reversely. The snakelike bionic robot is better in joint flexibility, the motion posture of the snakelike bionic robot is closer to that of a snake, and energy consumption is low.

Description

technical field [0001] The invention mainly relates to the field of bionic robots, in particular to a snake-shaped bionic robot based on flexible telescopic joints. Background technique [0002] Special robots, especially "footless" robots, have broad application prospects in places where radiation, poisonous, dark or narrow pipelines are not suitable for human work. Existing bionic robots all have rigid joints, that is, joints that cannot be stretched. Such robots are difficult to simulate the movement posture of biological snakes, and it is difficult to help humans complete the work that needs to be done in non-fixed-point projects. Therefore, it is meaningful to design a bionic robot with snake gesture movement. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the technical problems existing in the prior art, the present invention provides a snake-shaped bionic robot with flexible and telescopic joints, which ...
