Embodiment Construction

[0024] The present invention proposes a dual-purpose mobile robot with wheels and feet. The present invention will be further described below in conjunction with the accompanying drawings.

[0025] In Fig. 1, Fig. 2, and Fig. 3, the robot adopts a wheel-leg combination motion mode and carries out a modular design to ensure fast and flexible movement of the robot; Four legs with dual-purpose functions of wheels and feet: front left leg 2, rear left leg 3, rear right leg 4, front right leg 5, and the axis is at half the thickness of the vehicle body. On-board computer 26 is fixed on the bottom plate of car body 1; calf battery 9 is fixed in shank 6, and is used for providing energy for on-board computer, built-in camera and expansion plug-in. A built-in camera 21 is fixed in the calf 6 .

[0026] The structure of each leg is that the first motor 23 as the first-stage power input source is fixed on the bottom plate of the car body 1 through the mounting base 22, the first motor ...

Abstract

The invention belongs to a wheels and feet dual-purpose mobile robot in a robot technical field. The invention adopts a movement mode of combined wheels and feet; two long sides of a bodywork are respectively provided with four legs of the same structure with the duel-purpose of wheels and feet; the inside of the bodywork is provided with two batteries which provide energy for an on-board computer, an interior camera and an extended plug-in. Each leg comprises a thigh and a lower leg, with a power input unit of two levels; and the wheel mode and the foot mode are switched through a clutch. A first motor is fixed on a bottom plate of the bodywork through an insulation seat; a first shaft is fixed on a side of the bodywork by a seat, and the interior camera is equipped inside the bodywork as eyes of the robot; the on-board computer is taken as a planning and controlling center of movement of the entire robot; a plurality pony wheels are taken as driven wheels of which the driven movement or rotating termination is controlled by an electromagnetic contracting brake. By carrying out modularization design, the invention guarantees the rapid and flexible movement of the robot, multiple movement manners, strong ground adaptability and changes of movement gesture aimed at special landforms, which is favorable to reduce energy consumption.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a dual-purpose mobile robot with wheels and feet. Background technique [0002] There are usually two ways for robots to move: wheeled and articulated. The wheeled structure has the characteristics of fast moving speed, good steering, and convenient driving control; however, it has a small landing area, poor wall adaptability, poor obstacle avoidance ability, and poor mobility in unstructured environments. The articulated structure generally adopts the form of multi-joint connecting rods connected in series. It has low requirements on the road surface and can cross obstacles and walk through special roads such as sandy land and swamps; however, it has disadvantages such as large movement intervals, slow speed, and difficult drive control. Usually, a mobile robot has only one movement mode. Therefore, there is an urgent need for a robot structure with compact structur...
