This sensor is mainly intended researchers involved in robotics. There are several robotics sensors that are supported by official ROS packages and many more supported by the ROS community. read RPLIDAR raw scan result using RPLIDAR's SDK. Also I have published Firmware code and lidar ROS node. PCL based ROS package to Detect/Cluster --> Track --> Classify static and dynamic objects in real-time from LIDAR scans implemented in C++. robotics) submitted 3 years ago by senorstallone I'm looking for efficient and easy to implement/integrate 2d Lidar Scan Matcher for local mapping construction. For this application, the lidar is 2D and is in a small package. ibeo Wide Angle Scanning (ScaLa) Sensor Introducing the world's first automotive mass production laser scanner , now available from AutonomouStuff. For the MIT RACECAR, the lidar on this car is at a smaller scale, yet presents some of the same fundamental issues when combining with other onboard sensors. The data used for evaluation is a two-step L-M Optimization as shown in Figure 6. RS-LiDAR-16 is designed with 16 powerful laser beams capable of continuous fast-speed scanning on an amazingly high data rate of 320,000 points/second. io is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.
