How a Robot Vacuum With Lidar and Camera Navigates

Many robot vacuums aren't able to navigate around obstacles. This can be a problem, especially when it causes the apocalypse.

A robot vacuum equipped with LiDAR navigation and gyroscopes does a better job in creating a precise map and navigating around obstacles. They are generally more expensive than other models.

LiDAR

A robot vacuum that utilizes lidar can create detailed maps of your home. This allows it to move more efficiently around furniture and objects and avoid obstacles in its route. Lidar is a key feature of premium robotic cleaners, which tend to be more expensive than their budget-friendly counterparts.

A LiDAR sensor functions as a spinning laser. Thousands of times per second the sensor releases laser beams and records the time it takes for them to reflect back into itself. By doing this it is able to determine the exact distance between the robot and any nearby object, down to the centimeter.

The sensor works together with other sensors, like cameras and gyroscopes, to create a complete image of the environment. Cameras provide images, while the laser scanner collects data on the shape and location of objects. Gyroscopes are used to determine the orientation and direction of the robot.

Many robots are equipped with drop detectors. These are activated whenever the robot is near a high threshold or any other obstacle that it isn't able to traverse without causing damage or getting stuck. There are also wall sensors that stop them from pinging against walls or furniture pieces and generating a lot noise, or possibly damaging them.

A robot equipped with lidar can also adjust its course to adapt to changes in the surroundings. This could be due to a new piece of furniture being placed in the room, or even day-to-day changes like children rearranging their toys across different areas of the house. High-end models that have lidar sensors can analyze these changes in real-time, unlike cheaper robots that use bump sensors. They can then alter their speed and direction according to the change.

Some of the top robots equipped with lidar can detect a change in flooring, such as when a robot goes from a hard floor to carpet. These are useful features that make a robot that has lidar significantly more efficient than its low-cost counterparts that rely on simple bump sensors to try and avoid obstacles.

Gyroscope

The majority of robot vacuums come with sensors that assist them to navigate. It doesn't matter if they're using 3D structured light or laser navigation, monocular or binocular vision-based obstacle avoidance or just a simple gyroscope, these sensors aid the robot in its ability to create maps of your home and avoid obstacles that could block the path to cleaning. If you want your robot to stay clear of cords, area rugs, shoes, or furniture legs, this type of advanced obstacle detection is critical.

Sensors like gyroscopes monitor the speed of rotation of the robot wheels. They also help determine the location of a device within aircraft, ships, and mobile phones. Combined with other sensors, such as cameras or LiDAR sensors, these sensors allow the robot create a detailed map of the area and help it navigate it effectively.

Depending on the technology and pricing point of your robot vacuum, the navigation system may differ significantly. Certain models, such as the Dreame F9, feature a combination of camera and LiDAR to create a comprehensive map of your space and avoid obstacles that may be in its way. LiDAR navigation is faster and more precise than other sensor systems and allows you to create virtual boundaries for your robot as well as create no-go zones in your home.

Camera based navigation is slower and requires a light source, which can raise privacy concerns for some users. These systems are also more vulnerable to interference caused by reflective surfaces and complicated layouts.

Luckily, the majority of robot vacuums come with multiple sensors to make up for these limitations. They typically also include drop detectors that will stop the robot from falling down a flight of stairs or other major differences between levels. This is especially important for homes with multiple levels or homes with pets or children that could be injured when they fall from an open window or other high-offset levels. It is recommended to select models that have multiple sensor technologies rather than relying on a single type of navigation system.
