Played The Role Of The Sweeping Robot Eye Green Laser Pointer Radar
The "seeing" of the robot is actually positioning itself, positioning the target, and building a map. An electronic production expert with strong hands-on ability. It took half a year to make an "all-round radar attack robot". The ultrasonic radar is used for ranging, which can not only identify where the owner's shoes are but also show them to the owner. Radar ranging robot made by robot enthusiasts. At present, the application area of lidar is sweeping robots, which mainly realize obstacle avoidance and automatic path planning. Now some entry-level sweeping robots, in fact, the sweeping process is relatively simple, most of them only have the N-shaped sweeping ability, and the sweeping coverage area is also difficult to assess and guarantee. According to experts on sweeping robots, the fundamental reason is that it is invisible and unable to walk freely. At this time, the green laser pointer radar acts as the eyes of the sweeping robot. It allows it to clean purposefully.

There are shortcomings in lidar applications. The green laser pointer radar is so good. Why are robots using lidar rarely seen on the market? At present, except for some Chinese companies, only a few companies such as Japan and Germany have the ability to produce lidar. Its price is not low. For example, the price of lidar for Google's self-driving car is more than US$10,000 (said to be US$70,000). General service robots can't afford such expensive components. There is a reason for it to be so expensive. Generally, Lidar is difficult to develop in technology. Technically, the higher the accuracy, the better, and it is more difficult to achieve millimeter-level accuracy. To achieve such accuracy, there are big problems in the process: in terms of accuracy, to achieve long-distance millimeter-level accuracy, optical and measurement The craftsmanship actually has great requirements. In terms of speed, in fact, the price of traditional laser rangefinders is not expensive. You can buy one on Taobao for a few hundred dollars, but the measurement speed is extremely slow and may take a few seconds to complete. And the green laser pointer radar requires Complete thousands of measurements in one second. Therefore, the price of traditional lidar is also very expensive.
