MAPPING AND AVOIDING OBSTACLES: The YDLIDAR G4 is a 360º laser range scanner (LIDAR). With both a USB Type-C and PH2.0-5P bus interface, this YDLIDAR sensor runs off of 5V and uses a brushless motor drive to scan at a sampling frequency of 9000 readings per second up to 16m (52.4ft) distances.

YDLIDAR also has a user-friendly software interface and point cloud map to quickly get up and running.

Overview

360° SCANNING RANGING

The YDLIDAR G4 LIDAR has adopted a self-developed ranging module that can rotate 360 degrees. The G4G4 adapts to applications in different directions without adjustments. You can quickly outline and map your surroundings.

The G4 LIDAR is a 360-degree two-dimensional laser range scanner (LIDAR) developed by Shenzhen Yuedeng Technology Co., Ltd. After powering on, the YDLIDAR G4 starts rotating and scanning, for easy plug and play functionality. Users can get range scan point cloud data in a plane around the sensor. Range data of the point cloud is provided through the communication interface (Serial port/USB).

The YDLIDAR G4 provides two interfaces:

USB Type-C: Data communication and system power supply.
PH2.0-5P: Data communication and system power supply.

In the PH2.0-5P interface, the YDLIDAR G4 implements a 3.3V-TTL serial port (UART) as the communication interface, which runs at a baud rate of 230400. Users can connect an external system to this UART interface to receive real-time point cloud data, status, and control from the YDLIDAR G4.

The YDLIDARG4 uses a brushless motor driver that has a motor speed regulation function and provides a command interface instead of a hardware interface for Motor control. Please refer to the development document of this product.

The infrared laser power used by the YDLIDAR G4 meets the safety standard of the FDA Class I laser. When the system is operating, a laser and optical lensing system is used to transmit and receive laser signals to achieve high frequency ranging. To ensure optimal performance of the system optics, make sure that exposed lenses of the G4 are clean.

For secondary development, the YDLIDAR G4 defines the polar coordinate system internally. The polar coordinates of the system are the poles at the center of the rotating core of the G4, the specified angle is clockwise (but can be changed), and the zero position angle is located in the direction of the outlet opening of the G4 PH2.0-P interface line, as shown in the figure:

Applications

Communication mechanism

G4 communicates commands and data with external devices through the serial port. When an external device sends a system command to G4, G4 resolves the system command and returns a corresponding reply message. According to the command content, G4 switches the corresponding working status. According to the content of the message, the external system can parse the message and obtain the response data.

The YDLIDARG4 provides an easy-to-use hardware and software interface, which controls motor power, speed control, ranging frequency, and data output. A 3D CAD model of the G4 is available for system designers. A Windows graphical coding client with a corresponding SDK development kit and ROS development kit is also available for software designers.

Applications
