19. Appendix #LDS-01


19.1. Overview

360 Laser Distance Sensor LDS-01 is used for both TurtleBot3 Burger and TurtleBot3 Waffle. The LDS-01(LASER Distance Sensor) is a sensor which collects a set of distance data and send them to the host for the Simultaneous Localization and Mapping (SLAM) technique.

19.6. User guide

We are offering ROS package for LSD. The hls_lfcd_lds_driver package provides a driver for “HLS(Hitachi-LG Sensor) LFCD LDS(Laser Distance Sensor)”.


Due to firmware update (after buy it on Oct. 2017), the sensor is running directly when power in on.
