AsiaIndustrial NetNews: Technology changes life. It turns out that there is no special understanding of this sentence. The more things you can touch, the more you can find it. This sentence is a classic! In recent years, with the development of science and technology, intelligent sweepingrobotIt has quietly entered people’s family life, which is a great boon for otaku men and women who hate doing housework! It is the original intention of people to develop sweeping robots to replace humans to complete the ground cleaning work. At present, many brands of intelligent robots have successively launched laser navigation products. But won’t the intelligent sweeping robot with laser navigation and positioning run around?
What the hell is laser navigation?
Laser navigation seems to be “high and high”, but its basic principle is actually the same as laser ranging, that is, the machine calculates the distance from the obstacle in front of itself by measuring the time from laser emission to reception. It’s just that the laser ranging can be measured once, while the laser navigation needs to measure the distance of more points to calibrate the position of the machine itself, just like calibrating a point in a three-dimensional coordinate requires three coordinates. Navigation also requires multi-point ranging, even 360-degree continuous scanning several times per second, to record the movement path of the machine in space once.
What is the realization of laser navigation and positioning technology?
Laser navigation technology and laser ranging technology have the same principles, but laser navigation technology is a sublimation of laser ranging technology, which has higher requirements for computing power and higher integrated functional requirements for sensors. They have developed a lidar sensor. Initially, most of the lidar sensors that were relatively familiar to the public were used in the field of robot manufacturing.
In the field of Robotics, lidar sensors are used to help robots fully autonomously deal with complex and unknown environments, enabling robots to have sophisticated environmental perception capabilities. After continuous optimization, the lidar sensor has basically achieved modularization and miniaturization, and due to its wide application range and beginning to extend to more civilian fields, intelligent sweeping robots are currently a popular application field.
With the laser navigation and positioning intelligent sweeping robot, will it not run around?
At present, many brands of intelligent robots such as inxni and Neato are working on laser navigation. It has been a long time since the intelligent sweeping robot entered the household of ordinary consumers, but its arrival has not been fully recognized by consumers. The main reason for this is that the sweeping robots cannot meet the cleaning requirements, and many intelligent sweeping robots do not achieve true intelligence, and often run around and collide, repeat cleaning and other irregular work situations, and the efficiency is very low. With the help of laser navigation technology and built-in computing chips, the intelligent sweeping robot can draw an accurate picture of the interior of the space and calmly deal with any complex terrain.
Although the intelligent sweeping robot has a laser navigation machine, it can map the room floor, but it also needs intelligent algorithms to complete complex cleaning, so as to avoid the phenomenon of random collisions. The sweeping robot must achieve autonomous walking, “eyes” and “cerebellum”. “It is indispensable, otherwise it is impossible to see things around and intelligently “get around” these obstacles. At present, domestic SLAMTEC-Silan Technology Co., Ltd. uses lidar and SLAM algorithm to allow the sweeping robot to have its own “eyes” and “cerebellum”, enabling it to achieve functions such as autonomous positioning and navigation, autonomous obstacle avoidance, and automatic recharging.
What is the future development of intelligent sweeping robots?
With the test of inxni and Neato in the field of sweeping robots, and the excellent performance of laser-navigated sweeping robots, laser navigation has become the next hot spot in the sweeping robot industry competition. However, from the current market point of view, only a few products are equipped with laser navigation functions, and the real market explosion may take 1-2 years of technical precipitation and market breeding.
