Problems solved by technology

Although this sensor system can establish a global environmental map and obtain the obstacle status of the working environment in advance, it has a huge amount of data processing, complex algorithms, and difficulties in feature extraction and depth information recovery, so its application is too limited.
In addition, complex algorithms require a controller with corresponding computing power. This type of controller and the sensor itself are often expensive, which is why the price of some existing cleaning robot products is as high as thousands of dollars.

Embodiment Construction

[0015] As shown in Figure 1, the traveling mechanism of the present invention comprises a mechanical body 1 and a driving device; the mechanical body 1 is disc-shaped, used for installing the traveling mechanism and sensor system, and is also a carrier of other functional parts of the cleaning robot, such as a dust collection system, It includes: two dust brushes 1-1 and 1-3, a battery pack 1-2, a dust sweeping brush 1-4, a dust suction blower 1-5 and a dust collection box 1-6. The drive device consists of three drive units 2-1, 2-2 and 2-3.

[0016] As shown in Figure 2, the three drive units 2-1, 2-2 and 2-3 need to be distributed on the same circle 2-4 with the center of the disc of the mechanical body 1 as the base point, and the radius of the circle is reasonable according to the design requirements of the cleaning robot. Sure. The moving wheel axis of each drive unit coincides with the motor shaft axis of the drive motor, which is called the drive unit centerline, the d...

Abstract

A walking mechanism for the cleaning robot is composed of a mechanical main body, a drive system consisting of 3 drive units comprising drive motor, motor holder, linking axle and moving wheel, and a sensor system consisting of an infrared sensor group comprising 10-15 pairs of infrared sensors arranged at the front and back edges of main body and an ultrasonic sensor group comprising the ultrasonic sensors arranged at left and right edges of main body. Its advantage is omnibearing moving.

Description

technical field [0001] The invention belongs to the component parts of a robot in the field of mechatronics, and in particular relates to a walking mechanism of a cleaning robot, which can make the robot move in any direction in all directions. Background technique [0002] Cleaning robots are mainly used indoors, and perform cleaning work autonomously without manual operation. Most of the time, they complete the cleaning task of the home environment without supervision. Therefore, the robot needs to be able to avoid any objects in the room and to clean the floor of the room to the greatest extent. At present, many research institutions and enterprises have developed cleaning robot prototypes, and a small number of products have come out. Looking at these existing cleaning robots, the walking mechanism uses two-wheel drive plus an auxiliary universal wheel to form a robot-driven chassis, and independently controls the speed of the two wheels to achieve forward, backward and...
