LiDAR Robot Navigation
LiDAR robot navigation is a sophisticated combination of localization, mapping and path planning. This article will explain these concepts and show how they interact using an example of a robot reaching a goal in a row of crops.
LiDAR sensors are relatively low power demands allowing them to increase the life of a robot's battery and decrease the raw data requirement for localization algorithms. This allows for a greater number of variations of the SLAM algorithm without overheating the GPU.
LiDAR Sensors
The sensor is the core of the Lidar system. It emits laser pulses into the environment. The light waves hit objects around and bounce back to the sensor at various angles, based on the composition of the object. The sensor monitors the time it takes for each pulse to return, and uses that data to determine distances. Sensors are placed on rotating platforms, which allow them to scan the surroundings quickly and at high speeds (10000 samples per second).
LiDAR sensors are classified based on whether they are designed for airborne or terrestrial application. Airborne lidars are usually mounted on helicopters or an unmanned aerial vehicles (UAV). Terrestrial LiDAR is usually mounted on a robotic platform that is stationary.
To accurately measure distances, the sensor must know the exact position of the robot vacuum with obstacle avoidance lidar at all times. This information is usually gathered through a combination of inertial measuring units (IMUs), GPS, and time-keeping electronics. These sensors are used by LiDAR systems to determine the exact location of the sensor within space and time. This information is then used to build a 3D model of the surrounding environment.
lidar based robot vacuum scanners are also able to identify different kinds of surfaces, which is particularly beneficial when mapping environments with dense vegetation. For example, when a pulse passes through a forest canopy it is likely to register multiple returns. The first one is typically associated with the tops of the trees while the second is associated with the surface of the ground. If the sensor records these pulses separately this is known as discrete-return LiDAR.
The use of Discrete Return scanning can be helpful in studying surface structure. For instance forests can produce a series of 1st and 2nd return pulses, with the last one representing the ground. The ability to separate and record these returns in a point-cloud allows for detailed terrain models.
