Analysis of the positioning system of the sweeping robot

Robot vacuum cleaners, automatic washing machines, smart vacuum cleaners, robot vacuum cleaners, etc. They are also known as a kind of smart electrical appliances that can automatically perform the cleaning tasks of the floor in the room with a certain artificial intelligence. Generally, the brush and vacuum cleaner are used to suck the floor debris into the dustbin to complete the floor cleaning function. In general, robots that combine cleaning, vacuuming and mopping are also classified as sweeping robots.

Analysis of the positioning system of the scanning robot: the positioning is like human senses, so that the cleaner can know her exact position and prepare the scheduled cleaning. The technologies used today include RPS laser positioning system, vSLAM image displacement system positioning and wireless positioning. system within agencies. .

RPS laser positioning system: positioning is achieved by measuring the change in distance between the robotic sweeper and the environment using a 360° rotating laser sensor. The disadvantage of this positioning system is that the catheter is expensive, must be rotated continuously during operation, and has a very limited lifetime.

vSLAM Image Shift Positioning System: The ceiling image shift coordinate is recorded by scanning robots equipped with high resolution cameras. This mounting system has very high demands on the reference object on the ceiling. If attribute information. or if the geometric shape of the reference object is blurred, greatly affecting the positioning accuracy.

Indoor Positioning System for Wireless Carriers: Placing the Coordinates on the Charging Base and Measuring the Double Distance Change of the Robot Wireless Carrier Sensor. The coordinates obtained by this positioning method have high accuracy.
