How to select the right LiDAR ?
Are you looking for a LiDAR with certains specifications but you don’t know which one is suitable to your project ?
Do not panic, we are here to help you ! We provide you here with some comparisons of the products we are selling, and that are available on the market.
If you have any questions about the way LiDARs work or about their parameters, take a look on our previous article: What is LiDAR technology? . If you still have any questions, do not hesitate to contact our team .
Our website also features a webpage with a LiDAR comparison table.
In this article we are talking about specifications, which are given by the manufacturer. They might change depending of your environment.
First, we will describe low cost 360° angular range LiDARs . They are useful for mobile robots which require only 2D scanning. They will give you information about obstacles location. Only Slamtec S1 RPLIDAR seems to have good performances for an outside use. You can get an accurate map of your environment.

The state-of-the-art LiDARs are the 3D devices . You can create an accurate map of the environment in order to improve the robot mobility. Using the 3D space give new opportunities and features (environment with relief, passing through obstacles, 3D mapping, etc.). They are all long range scanner which can be used outside.

With these comparison tables, we tried to craft an overview of the different LiDARs available on the market. Indeed, it is necessary to choose its LiDAR according to the intended use for the latter. The different selection criteria can be financial, angular range, speed, power consumption and so on.
