Nowadays, the laser radar which is also known as the AGV lidar that is commonly used to help avoiding the obstacle or dangerous area automatically during products transmission. For the sick accuracy obstacle avoidance lidar, it is mainly combined with the laser technology and the radar technology that consists of a transmitter, an antenna, a receiver, a tracking frame and the information processing section. The antenna of robot avoidance laser radar is an optical telescope and the receiver adopts various forms of photodetector. The Lidar system consists of a single beam and a receiver system. The laser of the AGV lidar generates and emits a pulse of light that strikes the object and bounces back, it is eventually picked up by the receiver. The receiver accurately measures the travel time of the light pulse afterwards. The laser radar can scan and measure the obstacle through infrared lenses to form 3D cloud data to assist the robot for determining the position.

As this obstacle avoidance lidar, it works based on the principle of optical two-dimensional scanning and laser testing to achieve two-position area protection with the maximum 15 meters and 190 degrees for angle. The defense zone of AGV lidar includes protection zone and alarm zone. The maximum radius of the protection zones are optional that are 4 meters, 5 meters and 6 meters. It can detect the dark black object with the reflectivity as low as 1.8%. The maximum radius of the laser radar's alarm zone is 15 meters, it is able to detect the objects with the reflectivity as high as 20%.

Except for that, we produce mini lidar which can achieve the range of 270 degrees and the radius of 3 meters as the two-digit area detection and shape scanning. It has compact and flexible structure with accurate and cost effective performance. The overall size of the mini lidar is 8CM*8CM*9.5CM. It is the first level laser product which is harmless to human eyes and has the function of window contamination detection. The mini lidar's output can be cut off automatically when the actual detection distance dose not reach the standard protection distance.

-Advantages of sick accuracy obstacle avoidance lidar:

1.The performance of this AGV lidar reaches the international advanced level and meets the safety requirements of IEC61496 Type 3 and ISO 13849 PL d.

2.The user can set up the scanner zone as the required shape by connecting to the computer. The laser radar's maximum scanning radius is 15 meters and the angle can reach 190 degrees.

3.The laser radar has fast response speed that can measure 25000 times per second. The default response time of laser radar is 80m/s with 0.36 degrees angular resolution.

4.The robot avoidance laser radar adopts narrow-band filtering technology with strong anti-interference ability. All of our products have passed professional EMC design and rigorous tests to ensure the stable and efficient performance under complex or harsh electromagnetic environments.

5.The protection area and alarm area of the obstacle avoidance lidar's scanners are free to be set up for various of complex shapes according to the actual protection requirements. Users can set up to 16 area groups and realize the exchange of muti-area groups through external input signals.
