LR1200E2 · 905 nm Laser Rangefinder Module
LR1200E2 ROS 2 driver: range node, topics, launch files
The ROS 2 package reads the LR1200E2 over a serial port at 115200 baud and publishes sensor_msgs/msg/Range in metres. Install from the driver repository, pass the port and model name, and the topic appears in RViz.
Install and run
cd ~/ros2_ws/src\ngit clone https://github.com/ErdiTech/erdi-lrf-drivers\ncd .. && colcon build --packages-select erdi_lrf_ros2\nsource install/setup.bash\nros2 run erdi_lrf_ros2 range_node --ros-args -p port:=/dev/ttyUSB0 -p baud:=115200 -p model:=LR1200E2Topics and parameters
| Name | Type / value | Note |
|---|---|---|
| /range | sensor_msgs/msg/Range | distance in metres, frame_id = lrf_link |
| port | string | serial device |
| baud | 115200 | published baud rate of the LR1200E2 |
| model | LR1200E2 | selects the frame profile |
Examples
erdi-lrf-ros2-examples adds launch files, an RViz configuration, a fake node for bench work and median / outlier filters for the LR1200E2.
