LiDAR robots navigate by using a combination of localization and mapping, and also path planning. This article will introduce the concepts and show how they function using an example in which the robot is able to reach a goal within a plant row.
LiDAR sensors are low-power devices that prolong the battery life of robots and decrease the amount of raw data required to run localization algorithms. This enables more variations of the SLAM algorithm without overheating the GPU.
LiDAR Sensors
The core of lidar systems is their sensor that emits pulsed laser light into the surrounding. These light pulses strike objects and lidar robot Vacuum and Mop bounce back to the sensor at various angles, based on the composition of the object. The sensor monitors the time it takes each pulse to return and utilizes that information to calculate distances. Sensors are mounted on rotating platforms, which allow them to scan the surrounding area quickly and at high speeds (10000 samples per second).
LiDAR sensors are classified based on whether they're designed for airborne application or terrestrial application. Airborne lidar systems are usually mounted on aircrafts, helicopters, or unmanned aerial vehicles (UAVs). Terrestrial LiDAR systems are usually mounted on a stationary robot platform.
To accurately measure distances, the sensor must be able to determine the exact location of the robot. This information is usually captured through a combination of inertial measurement units (IMUs), GPS, and time-keeping electronics. LiDAR systems use sensors to calculate the precise location of the sensor in space and time. This information is then used to create an 3D map of the surroundings.
LiDAR scanners are also able to detect different types of surface, which is particularly useful when mapping environments that have dense vegetation. When a pulse crosses a forest canopy, it is likely to produce multiple returns. The first one is typically associated with the tops of the trees while the last is attributed with the ground's surface. If the sensor can record each peak of these pulses as distinct, it is referred to as discrete return LiDAR.
Discrete return scanning can also be useful for analysing surface structure. For example forests can yield an array of 1st and 2nd returns, with the last one representing bare ground. The ability to separate and record these returns in a point-cloud allows for detailed models of terrain.
Once an 3D model of the environment is created and the robot is capable of using this information to navigate. This involves localization and building a path that will take it to a specific navigation "goal." It also involves dynamic obstacle detection. This is the process that identifies new obstacles not included in the original map and then updates the plan of travel accordingly.
