YDLIDAR G4 Lidar Triangulation 360° 16m Scan Ranging for ROS Robotics Support ROS1 ROS2

The YDLIDAR G4 is a high-performance 360-degree triangulation laser scanner offering a 16-metre ranging distance for advanced robotic applications. Designed with full ROS 1 and ROS 2 support, it is an ideal choice for students, educators, and hobbyists building autonomous mapping and navigation systems.

Class 1 eye safety compliance

Featuring a low-power infrared emitter and PWM laser control, the G4 Lidar complies with FDA Class 1 safety standards. This ensures the device is completely safe for human eyes during operation in educational and maker environments.

Adaptable mounting bracket

The included mounting bracket allows you to easily secure the G4 Lidar to a wide variety of robotic chassis and mobile platforms.

Full 360-degree scanning

The scanner rotates 360 degrees to capture a complete outline of the surrounding environment, enabling swift and accurate mapping. This omnidirectional range makes it highly adaptable to diverse spatial applications.

Ultra-thin integrated design

Standing at just 41mm high, the compact profile integrates the drive system, rotation system, and motor. This unified design delivers more precise, reliable, and space-efficient performance on your robot.

Lidar mapping and navigation

Utilise the G4 Lidar to build accurate 2D maps of indoor spaces and implement autonomous navigation algorithms. It integrates seamlessly with ROS-based navigation stacks for precise localisation.

Advanced 3D vision mapping

Combine the sensor with compatible cameras to achieve RTAB-VSLAM 3D vision mapping and navigation. This allows your robot to construct detailed three-dimensional representations of its environment.

Dynamic obstacle avoidance

Implement multi-point navigation and dynamic obstacle avoidance to help your robot safely navigate complex environments. The real-time ranging data ensures prompt detection of moving obstacles.

Real-time lidar tracking

The high-frequency scan rate allows for precise target tracking and object following. This makes it suitable for advanced robotics projects requiring interaction with moving targets.
