NOTE: The 360 Laser Distance Sensor LDS-01 for TurtleBot3 uses molex 51021-0800 and 53048-0810 instead of the basic housing and connector.

LDS for TurtleBot3

The LDS-01 is used for TurtleBot3 Burger, Waffle and Waffle Pi models.

User Guide (for ROS)

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).

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

Preparations

WARNNING : The wiring colours of LDS-01 could differ from the picture by manaufacturers.

Download firmware and run

  1. After connecting USB to PC, select Tools -> Board -> OpenCR Board in Arduino IDE.
  2. Change Tools-> Port to the port to which the board is connected.
  3. In the Arduino IDE Examples, select the firmware for LDS (File -> Examples -> OpenCR -> Etc -> LDS -> drawLDS).
  4. Click Upload icon in the Arduino IDE that displays the red circle to build and download the firmware. When the download is completed, the firmware is automatically executed.
