Outdoor GPS navigation and positioning technology is mainly used in all-weather outdoor transport AGV in large scenes. It cooperates with two-dimensional laser radar, three-dimensional laser radar, machine vision, etc. to form a comprehensive environmental perception system to generate high-precision word-number maps on site, so that AGV has the current unmanned vehicles. With the core technology and performance in the field, problems such as outdoor navigation, ground slope restrictions, and severe weather environment restrictions that traditional AGV cannot handle are easily solved.
After long-term research and development, the Yufeng Intelligent Technology Team has mastered the vision-centric navigation technology, mainly including natural environment, beacon positioning technology, visual synchronization positioning and mapping technology (SLAM), autonomous navigation technology, etc. The obvious advantage of visual navigation is passive information navigation, which is friendly and non-destructive to the working environment.
Low cost, high speed and high precision, intelligent autonomous navigation, compared with lidar navigation, visual navigation has a very high cost-effective advantage for specific work scenarios. Stable motion control, optional arc or right angle steering, free path setting; multiple safety anti-collision systems such as laser, mechanical, sound and light; select core sensors and hardware from domestic and foreign brands.
Yufeng smart magnetic navigation technology uses tapes on the road surface instead of burying metal wires under the ground, and realizes guidance through magnetic induction signals.
Its flexibility is better than that of wire guidance, it is easier to change or expand the path, and the tape laying is simple and easy. It is suitable for occasions where the path is simple, the line is not very long, and the environment is relatively clean.
Such as the production line of the electronics industry, the material delivery of pharmaceutical companies and food companies, etc.
Yufeng Intelligent is the first to use three-dimensional (multi-line) lidar as the core navigation module on the industrial handling AGV.
Take the 16-line laser sensor of Velodyne in the United States as an example. Its information volume is 16 times that of the two-dimensional laser radar. Therefore, it can not only achieve accurate positioning and navigation, but also enable the AGV to have a true 360-degree safety and anti-collision performance without dead ends. , More importantly, it fundamentally solves the problem of outdoor operations for handling AGV.
Yufeng Intelligent 3D laser AGV series products realize all-weather indoor and outdoor operations and expand the use space of AGV.
Most of the laser navigation AGVs on the market use two-dimensional (single-line) lasers as the core navigation module. The advantages of two-dimensional laser technology are stable performance, strong scene adaptability, and high comprehensive accuracy. On the basis of the existing laser + beacon positioning, Yufeng Intelligent integrates the robot synchronous positioning and mapping technology (SLAM), so that the AGV can still accurately locate and navigate when there is no reflector beacon in the working area, which improves the product quality. universality and flexibility.
