Mobile robot chassis and omnidirectional mobile robot

Abstract

The invention specifically discloses a mobile robot chassis and an omnidirectional mobile robot. The mobile robot chassis comprises a protective frame, a bottom plate is fixed to the top surface of the protective frame, a supporting plate is fixed to the top surface of the bottom plate, and the left end and the right end of the bottom surface of the bottom plate are separately connected with a second connecting assembly and a first connecting assembly, wherein the first connecting assembly and the second connecting assembly are correspondingly connected with a first driving assembly and a second driving assembly; the omnidirectional mobile robot using the chassis comprises a shell, wherein a motion controller, a jacking device and a laser radar device are arranged in the shell; the motioncontroller is fixed to a supporting plate; the jacking device and the laser radar device are both fixed to the bottom plate; a plurality of ultrasonic radars are arranged at the periphery of a shell side plate and the protective frame; a voice broadcast box is embedded on the left side of the shell side plate; and two-dimensional code readers are separately arranged at the jacking end of the jacking device and the bottom of the bottom plate. The omnidirectional mobile robot has stable and reliable operation and realizes intelligent movement and automatic obstacle avoidance.

Description

technical field [0001] The invention relates to the technical field of mobile robots, in particular to a mobile robot chassis and an omnidirectional mobile robot. Background technique [0002] With the continuous development of the manufacturing industry, automated handling and transportation equipment will develop in the direction of intelligence and informationization. Most of the currently used omnidirectional mobile robots are chassis wheels composed of mecanum wheels and motors as the driving force to drive the robot to move in all directions. However, this driving method directly drives the mecanum wheels to rotate through the motor. In this driving mode, the motor will vibrate significantly during the start or stop process of the mobile robot, causing the cargo to be transported to slide forward or backward, thereby deviating from the center of gravity of the mobile robot and causing the cargo to fall. At the same time, the existing omnidirectional mobile robot Most ...

Most of the currently used omnidirectional mobile robots are chassis wheels composed of mecanum wheels and motors as the driving force to drive the robot to move in all directions. However, this driving method directly drives the mecanum wheels to rotate through the motor. In this driving mode, the motor will vibrate significantly during the start or stop process of the mobile robot, causing the cargo to be transported to slide forward or backward, thereby deviating from the center of gravity of the mobile robot and causing the cargo to fall. At the same time, the existing omnidirectional mobile robot Most of them use magnetic strip navigation, it is difficult to realize the intelligent movement and automatic obstacle avoidance of the robot, and it does not have the jacking function
