How Robot Vacuums Work
How does a robot vacuum work?
That is probably what you are wondering when you see the useful inventions buzzing around and cleaning homes without human intervention. Whether you own a cleaning robot or you are just curious, it would be fun to know how they work.
How Do Robot Vacuums Sense Objects?
To start, the main thing that a robot vacuum is able to achieve is the ability to move around freely to clean a room without bumping into things. To achieve that a robot is equipped with a sensor.
A robot does not see the world in the same way that we do. Even when it is equipped with a camera, it does not “see” as we do. The various sensors in a robot will determine how a robot will maneuver around, under, and through objects.
Different models would have different number of sensors but most have these types of sensors:
- Cliff sensor
- Obstacle sensor
- Wheel sensor
- Wall sensor
Most robot vacuums have more than one of each type to help it navigate a room.
How Do Robot Vacuums Map The Area?
Another technology used by robot vacuums would be mapping. Now, there are two ways that this is achieved. The first one is through digital cameras that capture images of the surrounding and is used by the robot to create a map of the area.
The second method is to use LIDAR, a kind of radar which is used to map the areas where it can and cannot go. If you can see the maps drawn by the robots using LIDAR, you would see that it looks a lot like the floor plan of a room. It marks off the places where it can and cannot go. Models such as the iClebo ALPHA boasts progressive mapping technology, making it a leading model when it comes to properly map an area.
There you have it - the technology behind robot vacuums that make them popular today.
