Lidar Robot Vacuum: 10 Things I'd Loved To Know In The Past

Lidar Robot Vacuums Can Navigate Under Couches and Other Furniture

Lidar-enabled robot vacuums have the ability to navigate under couches and other furniture. They offer precision and efficiency that is not achievable with camera-based models.

These sensors spin at lightning speed and record the time it takes for laser beams to reflect off surfaces, creating an accurate map of your space. There are some limitations.

Light Detection and Ranging (Lidar) Technology

Lidar operates by scanning an area with laser beams, and analyzing the time it takes for the signals to bounce back from objects before reaching the sensor. The data is then processed and converted into distance measurements, which allows for a digital map of the surrounding area to be constructed.

Lidar is used in many different applications, ranging from airborne bathymetric surveys to self-driving vehicles. It is also used in construction and archaeology. Airborne laser scanning employs radar-like sensors that measure the sea surface and create topographic maps, whereas terrestrial laser scanning uses a camera or a scanner mounted on a tripod to scan objects and surroundings at a fixed point.

Laser scanning is used in archaeology to create 3D models that are extremely precise and take less time than other techniques like photogrammetry or triangulation using photographic images. Lidar is also used to create high resolution topographic maps. This is particularly beneficial in areas with dense vegetation, where traditional mapping methods are impractical.

Robot vacuums equipped with lidar technology are able to use this data to pinpoint the size and location of objects in a room, even if they are obscured from view. This allows them to move easily over obstacles such as furniture and other obstructions. Lidar-equipped robots can clean rooms more quickly than  models that 'bump and run, and are less likely get stuck under furniture and in tight spaces.

This kind of smart navigation is especially useful for homes that have several types of flooring, as the robot is able to automatically alter its route according to the type of flooring. If the robot is moving between plain flooring and thick carpeting for instance, it could detect a change and adjust its speed accordingly to avoid collisions. This feature decreases the amount of time you spend "babysitting" the robot and frees up your time to concentrate on other tasks.

Mapping

Using the same technology used for self-driving cars lidar robot vacuums map out their surroundings. This lets them navigate more efficiently and avoid obstacles, leading to better cleaning results.

The majority of robots make use of sensors that are a mix of both that include laser and infrared to detect objects and build visual maps of the surrounding. This mapping process, also known as routing and localization, is a very important part of robots. This map allows the robot is able to determine its position in the room, and ensure that it does not accidentally hit furniture or walls. The maps can also help the robot design efficient routes, thus reducing the amount of time it takes to clean and the amount of times it has to return to its base to charge.

Robots detect fine dust and small objects that other sensors could miss. They can also spot drops or ledges too close to the robot. This prevents it from falling and causing damage to your furniture. Lidar robot vacuums are also more effective in navigating complex layouts than budget models that rely solely on bump sensors.

Some robotic vacuums, like the ECOVACS DEEBOT are equipped with advanced mapping systems that can display maps in their apps so that users can see where the robot is located at any time. This lets users personalize their cleaning by setting virtual boundaries and no-go zones.

The ECOVACS DEEBOT creates an interactive map of your house by using AIVI 3D and TrueMapping 2.0. With this map the ECOVACS DEEBOT will avoid obstacles in real-time and determine the most efficient route for each space and ensure that no place is missed. The ECOVACS DEEBOT can also recognize different floor types and adjust its cleaning mode to suit, making it easy to keep your entire house clean with minimal effort. For example the ECOVACS DEEBOT can automatically switch to high-powered suction if it comes across carpeting, and low-powered suction for hard floors. In the ECOVACS App you can also establish no-go zones and border areas to restrict the robot's movements and prevent it from accidentally wandering in areas that you do not want it to clean.

Obstacle Detection

Lidar technology gives robots the ability to map rooms and identify obstacles. This can help a robot cleaner navigate a room more efficiently, and reduce the amount of time it takes.

LiDAR sensors use the spinning of a laser to determine the distance of nearby objects. When the laser strikes an object, it reflects back to the sensor, and the robot is able to determine the distance of the object based on the time it took the light to bounce off. This lets robots navigate around objects, without hitting or being trapped by them. This could cause harm or break the device.

The algorithms consider variables such as the shape, size, and number of sensor points as well as the distance between sensors. The algorithm also considers how close the sensor is to the object, which can greatly impact its ability to precisely determine the set of points that describe the obstacle.

After the algorithm has identified the set of points that depict an obstacle, it attempts to identify cluster contours that correspond to the obstruction. The resultant set of polygons must accurately depict the obstruction. To form an accurate description of the obstacle, each point in the polygon must be linked to another in the same cluster.

Many robotic vacuums rely on a navigation system known as SLAM (Self Localization and Mapping) in order to create a 3D map of their space. SLAM-enabled vacuums have the ability to move more efficiently through spaces and cling to corners and edges more easily than non-SLAM vacuums.

The mapping capabilities can be particularly useful when cleaning high surfaces or stairs. It can enable the robot to design the path to clean that eliminates unnecessary stair climbing and decreases the number of passes over a surface, which saves energy and time while making sure that the area is properly cleaned. This feature can help the robot to navigate and keep the vacuum from accidentally bumping against furniture or other objects in a room when trying to reach a surface in another.

Path Planning

Robot vacuums can become stuck under large furniture or even over thresholds, such as those at the doors of rooms. This can be frustrating for owners, especially when the robots must be removed from furniture and reset. To prevent this from happening, a range of different sensors and algorithms are employed to ensure that the robot is aware of its surroundings and can navigate around them.

A few of the most important sensors are edge detection, cliff detection, and wall sensors for walls. Edge detection alerts the robot to know if it is approaching the wall or piece of furniture so it won't accidentally bump it and cause damage. The cliff detection is similar, but warns the robot in case it gets too close to the edge of a staircase or cliff. The final sensor, wall sensors, aids the robot to navigate around walls, keeping away from the edges of furniture, where debris can accumulate.

When it is time to navigate an autonomous robot equipped with lidar can utilize the map it's made of its environment to create an efficient route that ensures it is able to cover every corner and nook it can get to. This is a major improvement over previous robots that would simply drive into obstacles until the job was complete.

If you have an area that is complicated, it's worth the extra money to invest in a machine that is able to navigate. With lidar, the top robot vacuums will create an extremely precise map of your entire house and intelligently plan their route by avoiding obstacles with precision and covering your space in a systematic method.

If you have a simple room with a few large furniture pieces and a simple arrangement, it may not be worth the extra cost to get a high-tech robotic system that requires expensive navigation systems. Also, navigation is a huge factor that drives cost. The more expensive your robot vacuum is in its design, the more it will cost. If you're working with limited funds, you can still find excellent robots with good navigation that perform a great job of keeping your home spotless.
