Problems solved by technology

[0002] Automated Guided Vehicle (AGV) is a kind of mobile robot and an important equipment in modern manufacturing industry. Laser guidance is a navigation method adopted in the mid-1990s, but most of the current AGV laser navigation needs to install reflectors around the AGV operation as a positioning device, resulting in greatly limited application scenarios

Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0016] see figure 1 A ROS-based AGV car laser navigation system shown includes an upper computer and a lower computer installed in the AGV car, and a wireless communication module is installed in the upper computer and the lower computer, and the user communicates with the AGV car through the upper computer. The lower computer sends instructions, and at the same time monitors the position, status and voltage status of the AGV car. When an emergency occurs, the user can intervene in the lower computer system of the AGV car through the upper computer to avoid dangerous accidents;

[0017] In the present embodiment, the upper computer is a PC tablet computer, the display has a touch screen function, and the operating system is windows system and RO...

Abstract

The invention discloses an AGV vehicle laser navigation system based on an ROS. The AGV vehicle laser navigation system based on the ROS comprises an upper computer equipped with the ROS and a lower computer installed inside the AGV. The upper computer and the lower computer are equipped with wireless communication modules for data information exchange. The user upper computer transmits an order to the lower computer of the AGV vehicle to control a moving state of the AGV vehicle. The lower computer comprises a build-in ROS decision module, a laser navigation module, a power supply management module, a safety protection module and a driving module. The decision module is connected to the upper computer through a wireless communication module. A router is installed between the upper computer and a lower computer. Identical parameters are configured in ROS_MASTER_URI of a upper computer system and ROS_MASTER_URI of a lower computer system in order to realize information issuing and subscription of the upper computer and the lower computer. The navigation system uses an ROS distributed architecture and an open source code to effectively reduce development difficulties of the AGV and accelerate a development process.

Description

technical field [0001] The invention relates to the technical field of mobile robot navigation, in particular to a ROS-based AGV trolley laser navigation system. Background technique [0002] Automated Guided Vehicle (AGV) is a kind of mobile robot and an important equipment in modern manufacturing industry. Laser guidance is a navigation method adopted in the mid-1990s, but most of the current AGV laser navigation needs to install reflectors around the AGV operation as a positioning device, which greatly limits the application scenarios. For the laser navigation method without a reflector, since there is no track, no auxiliary positioning equipment, and the driving path is flexible and changeable, the free and stable movement of the AGV along any path is still a technical problem that needs to be solved urgently. [0003] The Robot Operating System (Robot Operating System, ROS) originated from the personal robot project of Stanford University and the robotics company Willo...
