Package Summary

The rplidar_python package


the rplidar_python package provides a solution for RPlidar sensor usage in ros. This packge also allow robot launches a 360 degree scanning map through gmapping module without twisting.

Hardware Requirements

to use rplidar_python, you should get a robot that provides odometry, like turtlebot. Also, you need a RPlidar sensor. Here we use RPLIDAR 360 laser scanner development kit.

we use RPlidar to replace kinect sensor and we mount it in the position of kinect , thus kinect tf frame is useful for RPlidar sensor as well.


to make a map by RPlidar, you should launch rplidar_gmapping_demo.launch.

roslaunch rplidar_python rplidar_gmapping_demo.launch



driver for RPlidar. Automatically starts sensor and convert data stream into sensor_msgs/LaserScan type. sensor publish topic every frame, one frame contain 360 laser data.
