Embodiment 1

[0019] S100: will The control panel is mounted on the chassis.

[0020] (Raspberry Pi, abbreviated as RPi) is a microcomputer the size of a credit card, and its system is based on Linux. It has all the basic functions of a computer. It is an ARM-based microcomputer motherboard. It uses SD / MicroSD card as a memory hard drive and can be connected to keyboards, mice, network cables and other equipment. It is widely used in various fields. In the present invention, Raspberry Pi 3Model B is selected. Its core is a 64-bit, 4-core ARM v8 chip, which needs to be installed with an operating system, such as the Debian-based Raspbian Jessie operating system.

[0021] Chassis is The chassis is a two-wheel differential drive, and the lidar sensor RPLIDAR is also installed on the chassis It is a 2D 360° laser radar based on the triangular ranging method, which is mainly responsible for collecting the distance and angle information between the mobile robot and surrounding obstacles ...

Embodiment 2

[0033] correspondingly, as Figure 5 As shown, the present invention also discloses a robot navigation system, which includes: The control board is installed on the mobile robot chassis; the first transplant unit is used to transplant the underlying driver files of the ROS system; the second transplant unit is used to transplant the unique driver files of the mobile robot; the compiling unit is used for the navigation algorithm source code to compile.

[0034] Wherein, the chassis is a two-wheel differential drive, and a laser radar sensor is also installed on the chassis to collect distance and angle information between the environment where the mobile robot is located and surrounding obstacles. The control board is respectively connected with the drive module, the sensor module and the storage module. The underlying driver files include USB interface driver files, motherboard driver files, and memory card driver files.

[0035] It also includes a storage unit, which is...

Abstract

The invention discloses a mobile robot navigation method. The method comprises the following steps that 100, a raspberry pi control panel is installed on a chassis of a mobile robot; 200, a bottom layer driver file of an ROS system is transplanted; 300, a special mobile robot driver file is transplanted; 400, source codes of a navigation algorithm are complied. A robot navigation algorithm can be conveniently modified / updated.

Description

technical field [0001] In general, the present invention relates to robots, in particular to a navigation method and system for a mobile robot. Background technique [0002] A mobile robot is an intelligent robot that works in a complex environment and has self-organization, autonomous operation, and autonomous planning. It integrates computer technology, information technology, communication technology, microelectronics technology, and robotics. Mobile robots can replace humans to complete some tasks. For example, household sweeping robots complete the task of cleaning indoors; AGV cars efficiently complete the transportation of goods in industrial environments and logistics warehousing; The soil samples were collected in the environment. Mobile robots use different sensors depending on their application environment and movement methods, such as vision sensors, laser radar, ultrasonic sensors, etc. But the core technology of mobile robots has always been around navigation...
