LDS-03
The previous LDS sensor(LDS-02) is discontinued and replaced with LDS-03 since 2025.
Overview
- 360 Laser Distance Sensor LDS-03 is a 2D laser scanner capable of sensing 360 degrees that collects a set of data around the robot to use for SLAM (Simultaneous Localization and Mapping) and Navigation.
- The LDS-03 is used for TurtleBot3 Burger and Waffle Pi models.
- Only Tx UART interface is available for the LDS-03 sensor.
- The USB interface(USB2LDS) supports easier connection to a PC or SBC.
