SLAM Robot which uses latest technology like ROS (Robotic Operating System) with Raspberry Pi and also interfaced with RPLidar a 360 degree Lidar, which sends those Laser scan value to the Matlab to map the environment. 360-degree omnidirectional laser scanning. This allows to do navigation with a very cheap sensor. This is an enormous problem. See section D.

The image on the left was captured from a scanning LIDAR sensor from inside a room. RPLIDAR is a low cost LIDAR sensor suitable for indoor robotic SLAM application. 360 Degree 8 m LiDAR held Sensor for ROS Robot Module LiDAR Scanner short Measuring Sensor held the range of 0. 5hz/10hz rotating frequency with guaranteed 8 meter ranger distance, current more than 16m for A2 and 25m for A3. High speed, long range LIDAR systems can cost several hundred dollars, but if you’d like to experiment with the technology, or your project would work just fine with 60 Hz scanning and a 2 meter range, tinyLIDAR could be a fun board to play with using Arduino compatible boards. Instead of data exported from their viewer software, it's a pcap captured with Wireshark or a another network capture tool that uses the standard pcap format. It can take up to 4000 samples of laser ranging per second with high rotation speed. LiDAR integration with ROS: quickstart guide and projects ideas In this post, you will learn how to connect and integrate your LiDAR with your PC or embedded system using ROS middleware on Ubuntu. Beefed up the XV-11 driver code to use all 360 degrees of each '2D plane' of a given Lidar scan at one rotation of the base (30 deg is bad anyway from base too close) Added checksum validation of each line (4 points) from the XV11 so we don't try to publish data with glitch in transmission (highly unlikely but possible). The UST-10LX is a scanning laser range finder (LiDAR) with a. 04 (x64) ROS Kinetic. The items in the drop down menu are generated based on the available frames in the tf transformation tree of the rosbag.
