According to IFR (International Robot Alliance) statistics, in 2014, the total sales volume of professional service robots worldwide was 24,200 units, up 11.5% year-on-year, and the total sales volume of home service robots was 4.7 million units, up 28% year-on-year. In the next three years, sales of professional service robots will increase to 152,000 units, and global sales of home service robots will reach 25.9 million units, which is about five times the size of 2014. How to be a better servant of human beings, in addition to more and more sensors, it is also crucial that the robot has a pair of eyes to "see" and then respond. But do you know how these robot eyes are formed? In fact, for robots, those laser radars are equivalent to their "eyes" to help them see the surrounding environment. Lidar is essentially similar to the bat's echolocation system, emitting laser light to the surroundings, and determining the distance of the object based on the time consumed by the reflection. From this, the orientation and surface shape of the surrounding objects are calculated. In practical applications, the service robot can achieve rapid response to obstacles through laser sampling, and carry out more rapid and timely autonomous obstacle avoidance. The Google driverless car is a specific application example, and the "corner" on the roof is the lidar. In addition to driverless, lidar can also be used for drones , as well as for positioning and obstacle avoidance systems for service robots. Although it sounds sci-fi, it is actually a relatively mature technology. The related fields have accumulated decades of research, and even open source programs are downloaded on the Internet. Before the dawn of the consumer-grade robot market , SiGe Technology took a fancy to this opportunity, in the service-oriented robot field, "to be the eye of a home robot ." SLAMTEC is located in Zhangjiang, Shanghai. It has 6 years of experience in developing robotic positioning navigation algorithms, laser sensors and robot hardware systems. Key products include low-cost laser ranging scanning sensors (RPLIDAR), laser-based real-time positioning and map construction navigation systems (SLAM), and a Zeus robotic universal platform for business environments. The company launched the first generation of laser radar RPLIDARA1 in 2014, and the price of hundreds of dollars is less than one-ninth of that of industrial-grade laser radar. Chen Shikai, CEO of Siwei Technology, said: "In the past, traditional laser sensors ensure performance through high-precision optical and mechanical components, but not every application requires industrial-grade accuracy, and there is no need to deal with industrial-grade extreme environments. So we Based on the triangulation technology, combined with computer vision technology, the targeted optimization of the algorithm makes the requirements on sensors and processors much lower, thus reducing the cost." After RPLIDARA1 has accumulated thousands of users, the comprehensive upgrade of RPLIDARA2 is undoubtedly more innovative. The following are some specific parameters: The sampling frequency of A2 is increased from 5Hz to 10Hz, and the number of sampling is increased from 2000 to 4000 times per second. Robots can get more dense sampling points, respond more quickly, and avoid obstacles in a timely manner. In terms of power supply mode, A2 replaces the traditional conductive slip ring with optical and magnetic fusion technology, reducing friction during operation and extending the design life of A2 to five years. RPLIDARA2 has redesigned the internal mechanical system to an overall height of only 4 cm. It is also the thinnest laser radar in the industry.
