Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] The object of the present invention is to provide a wheel-legged amphibious mobile robot with a variable angle of attack to solve the problems in the prior art. The robot has a compact structure and a simple structure. According to the requirements of three different modes of motion for the mobile performance of the robot, an amphibious mobile robot is innovatively proposed. At the same time, combined with the characteristics of the robot's own movement,...

Abstract

The invention discloses a wheel-legged amphibious mobile robot with a variable attack angle, and belongs to the technical field of robot structures. The robot is formed by three modules: a motion unit, a machine body trunk and a power device. The motion unit is used as a key structure and is mainly formed by a movement mechanism, a wheel train, a telescoping mechanism, a transmission device and the like. According to the robot, a gear rack drives the telescoping mechanism to rectilinearly move in a reciprocating way so as to push 'support legs' to stand up and draw back, so that the mutual switching of a wheel type and gait of the robot is realized; and under the transmission of a bevel gear train, paddles can rotate at any same angle at the same time, so that the motion attack angle of the robot is changed, and steering is realized. The robot provided by the invention can effectively adapt to complex rugged amphibious environments, and is capable of realizing a series of operation requirements on quickly moving, crossing obstacles, underwater steering and the like.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a wheel-legged amphibious mobile robot with a variable attack angle. Background technique [0002] Under the current research status, many work fields such as emergency rescue and disaster relief, archaeological exploration, and scientific research exploration are not suitable for humans to work in person. There is an urgent need for a robot that can replace humans to complete expected tasks safely and efficiently. Therefore, it is of great research significance to invent a mobile robot that can live amphibiously and adapt to different terrains. [0003] After a large number of investigations, it is found that most of the current mobile robots are very single in terms of drive mode and adaptability, and their comprehensive performance is low. The common mobile robots are mostly wheeled, legged and tracked. However, in the complex and harsh amphibious environment, these three typ...
