At present, most of the AGV robots in the market adopt the magnetic rail navigation technology, that is, stick a fixed tape on the ground, and when the electromagnetic induction system can feel the magnetic field, the AGV robot can travel on the pre-set route. It is unattractive and very easy to damage, resulting in high maintenance costs.
In this case, the laser radar navigation technology which can guide AGV to determine the best path, avoid obstacles easily and successfully reach their destination has obvious advantages.
Lidar is a radar system that detects the position and velocity of the target by transmitting laser beam. Its working principle is to send a detection signal (laser beam) to the target and then compare the received signal (target echo) reflected from the target with the transmitting signal. After proper processing, the relevant information of the target can be obtained, such as target distance, azimuth, altitude, speed, attitude, even shape and other parameters, so as to detect, track and identify the target.
The navigation technology can not only realize path planning, obstacle avoidance and high precision of 10mm light rain, but also has the advantages of high positioning accuracy, high path flexibility and high intelligence without installing additional reflector.
At present, with the development of market application, the requirement of AGV is higher and higher, and the traditional navigation method can not meet the needs of the public. For this reason, many AGV manufacturers began to turn to the laser radar navigation technology research and development.
In the future, AGV navigation technology will advance to a higher level of lidar navigation technology or become a future development trend.
