What Is The Laser Navigation Of A Robot Vacuum Cleaner?

The laser navigation of a floor-cleaning robot is a technology that enables positioning, mapping, and path planning through a laser radar (LiDAR). Its core principle is similar to "using laser radar to scan the environment, generate a map, and then plan the optimal route".The working process is roughly as follows:• The laser radar on the top of the floor-cleaning robot rotates 360 degrees to emit laser beams. When the laser hits obstacles such as walls and furniture, it reflects back. By calculating the round-trip time of the laser, the distance between the robot and the obstacles can be accurately measured.• Combined with its own movement status (such as moving distance and steering angle), a large amount of distance data is integrated to generate a real-time 3D map of the room inside the robot (i.e., SLAM technology, Simultaneous Localization and Mapping, applied to PUREATIC Robot Vacuum Cleaners, such as V6, N5, N8, X5 etc.). https://www.pureatic.co/collections/robotic-vacuum-cleaner/products/robotic-vacuum-cleaner-v6

• Based on the generated map, the navigation system will plan an efficient cleaning path (such as a zigzag route), avoiding repeated cleaning or missed areas, and at the same time, it can intelligently bypass obstacles.

It can complete cleaning tasks more efficiently and is a commonly used navigation method in mid-to-high-end floor-cleaning robots.
