Smart Navigation System of Roomba Vacuum Cleaners

The modern market offers a huge selection of robotic vacuum cleaners. These vacuum cleaners for cleaning services are characterized by low planting and compact dimensions to keep the opportunity to clean the furniture, which is inaccessible to traditional vacuum cleaners. They are designed to perform daily cleaning, which becomes an important touch in maintaining cleanliness, so the robot cleaner is designed to maintain the cleanliness between manual vacuuming.

Nevertheless, if you are one of those people who never vacuums, the robotic assistant will be able to make the floors and carpets cleaner than they are now, and you do not have to hit your finger. One of the most popular manufacturers of robotic vacuum cleaners is iRobot, which offers a variety of models in the market, from the basic model Roomba Red, Roomba 890 or 960, the technologically advanced Roomba Scheduler, and others.

The Navigation System of the Roomba Vacuum Cleaner

It is the Roomba navigation system that makes the vacuum cleaners robotic. There is a famous Roomba Red that uses the AWARE Robotic Intelligence System from iRobot, a system designed to reduce human intervention in the work of the robot as much as possible. Awareness system includes several sensors that collect data from the environment, send them to the microprocessor of the robot cleaner, after which the behavior of Roomba is regulated properly.

According to iRobot, the system can respond to new input data up to 67 times per second. The first thing that Roomba does when clicking the "Clean" button, measures the size of the room. After the robot establishes the dimensions of the room, it knows how long and far it needs to move in the cleaning process. In the meantime, the robot vacuum cleaner cleans, it avoids stairs and other kinds of height differences, using four infrared sensors on the front lower part of the robot. These are "Clipping Detectors", which constantly send infrared signals and, having received a negative signal, Roomba will immediately stop.

If the robot approaches the break, the signal will be lost. The main difference in models lies in the accuracy of navigation sensors. Older models, like Roomba Red, simply starts moving in the opposite direction, modern models of the same way clean the edge of the cliff. When Roomba Red crashes into something, its bumper activates the mechanical sensors that tell the robot system that it has encountered an obstacle. Then, a certain algorithm of actions is used that involves turning and trying to move forward until the robot can move forward.
