Robot Vacuums With Lidar Make Cleaning Easier

A robot vacuum can map its environment in order to avoid obstacles and navigate efficiently. This technology is akin to the technology utilized in aerospace and self-driving automobiles.

Simple robots have bump sensors that prevent them from scuffing up the paint on your chair or scratching its legs, but more advanced navigation systems like Lidar and SLAM are far better at avoiding the unexpected. This technology is costly.

Lidar

The big advancement in robot vacuums for the last decade has been lidar vacuum mop or light detection and ranging. Lidar is a sensor which sends laser beams out and records the time it takes for them to return. The data can then be used to create maps that are precise. Lidar makes it much easier for robots to navigate and avoid objects, especially in low-light environments.

Even though many modern robotic lidar-based Vacuums feature some form of obstacle-detection but they struggle to untangle cords, socks and other household items that can easily get tangled on the floor. A weak obstacle detection system can seriously affect the cleaning efficiency of a robot vacuum robot with lidar and cause a lot of wasted time. You'll have to stop it and manually remove the object it is stuck on.

The top robot vacuums that make use of lidar have powerful object detection capabilities which will ensure that your floors are clean and free of debris and tangles. These vacuums are also less likely to get stuck on furniture legs or other obstacles that are common in narrow hallways and tight spaces.

Some robots with lidar also come with digital keep-out zones which allow you to create a virtual boundary on the map to prevent the robovac from cleaning certain areas of your apartment or home. This can be very helpful in preventing your vacuum from accidentally cleaning up the costly area rug or the cat litter box.

Another advantage of a robot equipped with lidar is the capability to identify stairs better. Although getting a robot up stairs is still a difficult task, many models with lidar are able climb them with no difficulty.

Other sensors you might want to keep an eye on include infrared sensors that can detect furniture, walls and other objects that can help the robot navigate; 3D ToF sensor which uses reflection infrared to determine and calculate the position of objects and cliff sensors, which warn the vacuum when it gets close to an edge.

Gyroscopes

Gyroscopes are more common on robots with lower budgets and function as wheels that spin quickly to inform the robot vacuum cleaner with lidar of the position it's in with regards to obstacles. They are more prevalent on low-cost robots and work as quick-spinning wheels that let the vac know where it is in relation to obstacles. Some models can even use gyroscopes to create a basic home map which is useful to keep the track of your home and ensuring that you clean it up properly.

SLAM (Simultaneous Localization and Mapping) is another popular navigation system for robot vacuums. It is available at various prices. This method creates a 3-D map of your room permitting the robot to navigate in a way that is logical. This is a huge improvement over the older bounce-and bang robots that simply plough your space, bouncing off whatever they encountered until they were done.

In addition to creating maps, the majority of robots who use SLAM can display them in an app so you can see where your cleaner is at any time. You can also create no-go zones based on maps. This is particularly helpful for homes that have a lot of furniture, as it isn't easy to figure out the location of everything without an actual home map.

While SLAM is effective in a majority of situations, it's not as effective in detecting smaller obstacles, such as wires and cables that might be trapped in the vacuum's brush. This is a major drawback because robots are susceptible to take on these objects and causing damage.

Fortunately, the majority of robots that include SLAM come with obstacle detection technology, such as drop detectors. These sensors assist the vac avoid falling down stairs and other significant differences in floor level which could cause severe damage. Most robots come with cliff sensors, too which are beneficial when you have an animal who would like to leap over it to get to its food bowl or water. These sensors are usually placed on the bumpers of the vac and emit a signal when the vac is within range of something that could harm it.

Wall Sensors

The ability of a robot vacuum navigate around your home depends on a set of sensors. A low-cost model could utilize bump sensors to detect obstacles and a light that rotates to illuminate walls, however high-end models are much more sophisticated, including mapping, self-navigation systems that permit saving maps (with some data retaining or sending this information to a company) and digital keep-out zones to prevent robots from accidentally pinging cables or knocking down furniture legs.

Certain robots utilize what's known as SLAM or simultaneous localization and mapping. In essence, they map the room before beginning cleaning, and then refer back to this map throughout the cleaning. This makes them a lot more efficient, as they know exactly where they've been and can avoid repeating the same parts of the room. You can also view and share these maps in your robot's app, an excellent feature if you prefer to set up no-go zones or clean by the area.

Another important navigation sensor to look for is the gyroscope. Gyroscopes depend on spinning wheels or a quickly-rotating beam of light to determine the distance between your robot and obstacles within your home, using this data to create a virtual map the bot can reference as it moves around your space. Robots that don't have this technology could be stuck on cords and carpets, and may zig-zag across the floor instead of following the edges.

The most effective robots come with a variety of different obstacle avoidance techniques, which can include 3D structured light, 3D ToF (time of flight) and binocular or monocular vision-based and LiDAR. The more technologically advanced is, the more precise and effective your robot's navigation will be. This translates into more thorough, low-maintenance clean ups and the possibility of establishing zones that are not allowed to enter to protect your electronics and other valuables from damage caused by accidents. The most recent generation of gyroscopes which are more precise and perform well in dim lighting, can even detect a change in the ambient lighting in your home to aid the robot see more effectively.

Sensors Optical

A robot vacuum equipped with lidar navigation will generate an interactive 3D map that helps you navigate the space more efficiently and avoid hitting obstacles. It does this by releasing a laser beam that bounces off surfaces and then returns to the sensor. The sensor measures the time taken for the laser beam to return. This translates into distance measurements, and helps the robot build up a picture about the layout of your room.

As opposed to cameras, which are used in certain robots to map rooms, lidar vacuum cleaner is much faster and more precise. Depending on the model, a robotics device with lidar could include an "no-go" zone feature that lets you create areas that are restricted to your robot. In our testing, we found the best models that make use of this technology are the Neato Botvac D8 and iRobot Braava 350, which come with easy-to-setup "no-go" zones in the app.

iRobot Duo+, another fantastic option, makes use of LiDAR and sensors to create an accurate map of your home that it can use to navigate. The app allows you to control the mapping process, so you can adjust your home's boundaries as needed.

Other technologies that are used to improve robot navigation include 3D structured lights which measure distances through looking for reflective properties of objects, and 3D TOF (time-of-flight) which scans an area to measure the speed of light reflections and their direction. Some robots also use binocular and monocular vision to detect objects and avoid them.

All of these sensors work to enable robots to avoid obstacles in a variety ways, which is why they're an integral part of what makes these machines so convenient to have around. It is important to think about your needs before purchasing an automatic vacuum. Consider how long you'd like to devote to preparing your floors before cleaning, how many obstacles are in your home and if you'd like the robot to do more than just vacuum. Once you know what features are most important to you, we recommend creating a budget that covers the cost of a robot equipped with the technology you want.
