With the popularity of service robots, positioning and navigation is becoming a standard robot, which is inseparable from this key technology when it comes to autonomous movement, and this problem needs to be solved by lidar. A few years ago, because of the price, there are few suitable lidar products on the market for robots, until the emergence of Silan technology, this problem will be easily solved.

It is understood that the Silan science and technology team selected lidar as its research target at the beginning of its establishment, and put the entry point on the realization of low cost of lidar. In addition, the problem they have to solve is the navigation and positioning of the robot, and only by overcoming this problem can the robot really walk freely.

Adjust the technology to achieve the ultimate ratio of performance to price

Initially, lidar and autonomous positioning technology are only used in industrial and military fields, which are both different and similar to commercial and civilian applications. However, the general core technology and market needs must be the same, just like the high precision requirements of lidar, the high reliability and intelligence requirements of autonomous positioning and navigation will not change. To reduce the cost of lidar is not simply to control the cost and compress the profit, but to adjust the technology in essence.

In order to reduce the production cost and control the rate of good products at the same time, Silan Technology has created a new method of playing, that is, using the image method to design the lidar sensor and capture the picture displayed on the camera after the laser reaches the target object. the distance is calculated according to the change of the camera picture size caused by the difference in distance. At the same time, Silan Technology has established an automatic production line of independent research and development.

After years of research and development and practice, Silan Technology has a number of mature lidar products, which not only breaks the limitation that triangulation lidar is difficult to break through more than 20 meters, but also has a sampling rate of tens of thousands of times. refresh the trigonometric ranging radar standard in the industry many times. At the same time, a TOF laser ranging radar with a measuring radius of 40 meters is introduced, which can achieve stable ranging and high-precision mapping even under strong light interference.

SLAMTEC Mapper

In addition, Silan science and technology pioneered a new lidar category SLAMTEC Mapper also attracted the attention of the industry, according to reports, SLAMTEC Mapper is a set of map construction and real-time positioning as one of the new lidar category, including the third generation of high-performance SLAM engine and lidar, without any external dependence, power-on, suitable for robot navigation and positioning, environmental mapping, handheld measurement and other fields. With the technological advantages of high performance and low cost, at present, most of the service robots we can see in public places are based on Silan technology lidar products.

Creating a full-link robot positioning and navigation scheme based on lidar

Lidar is the first step for Silan technology to cut into robot positioning and navigation track, but in order to realize robot autonomous positioning and navigation, lidar alone is not enough, positioning and navigation is mainly divided into two parts, one is the sensor, the other is the realization of navigation algorithm. Silan Technology solidifies the processor into a chip by improving the algorithm principle and implementation details, and the emergence of SLAMWARE,SLAMWARE, a modular autonomous positioning and navigation system based on lidar, solves the robot's ability to walk, which integrates synchronous positioning and mapping (SLAM) based on lidar and supporting path planning functions.

Silan Technology Modular Positioning and Navigation set

Compared with the open source robot operating system ROS, Silan Technology's built-in SLAM algorithm creates a more accurate map, which can maintain high positioning accuracy even if disturbed by external interference. In practical application, in addition to using SLAM to build environmental maps and real-time positioning, Silan Technology also hopes that robots can automatically avoid obstacles and move freely in unknown environments. SLAMWARE adopts D* algorithm (dynamic heuristic path search algorithm), which enables the robot to move freely in an unfamiliar environment and avoid dynamic obstacles without entering the map in advance.

With the continuous upgrading of technology, currently Silan Technology SLAMWARE uses the latest SLAM 3.0 map optimization, compared with the traditional SLAM technology, Silan Technology SLAM 3.0 technology has a greater improvement, can achieve millions of square meters of real-time map construction ability, while has the active loop closure correction ability, can well eliminate the mileage cumulative error caused by long-time operation. At the same time, SLAM 3.0 uses SharpEdge fine composition technology to build high-precision, centimeter-level maps with ultra-high resolution. At the same time, the construction of the map rules, fine, to further improve the accuracy of positioning. No need for secondary optimization modification, directly meet the expectations of users.

Silan Technology ZUES Series

From the laser mine to the positioning and navigation system, Silan Technology has launched a universal service robot chassis ZEUS series, a set of constantly improving and sophisticated navigation and positioning solutions have been gradually formed. ZEUS is based on the modular positioning and navigation system independently developed by Silan Technology, and integrates ultrasonic, depth camera, fall prevention and other sensors, which can achieve independent positioning, mapping, path planning and other functions, and can walk flexibly even in the face of all kinds of complex scenes.

Silan Technology, which has been committed to autonomous robot positioning and navigation since its inception, has finally dominated 70% of the robot positioning and navigation market after years of efforts, becoming a leader in landing applications in the mobile robot industry, and further accelerated the development of the mobile robot industry.
