2.Installation size comparison

OVERVIEW：

YDLIDAR X4PRO is a 360 degrees two-dimensional rangefinder (hereinafter referred to as X4PRO) developed by EAI team. Based on the principle of triangulation, it is equipped with related optics, electricity, and algorithm design to achieve high-frequency and high- accuracy distance measurement. The mechanical structure rotates 360 degrees to continuously output the angle information as well as the point cloud data of the scanning environment while ranging.

Product Features:

360 degrees omnidirectional scanning ranging distance measurement

Small distance error, stable performance and high accuracy

Wide ranging distance

Strong resistance to ambient light interference

Low power consumption, small size and long service life

Laser power meets Class I laser safety standards

Adjustable motor speed, scanning frequency is 6~12Hz

High-speed ranging, ranging frequency up to 5kHz

Applications:

Robot navigation and obstacle avoidance

Robot ROS teaching and research

Regional security

Environmental scanning and 3D reconstruction

Navigation and obstacle avoidance of robot vacuum cleaner/ROS Learning robot

Development Kit：

The X4PRO development kit has the following components：

Note:

USB Adapter board has two USB TYPE C interface：USB_DATA、USB_PWR.

USB_DATA: Data powered interface. In most cases, this interface can be used to meet power and communication requirements.

USB_PWR: Auxiliary power supply interface. The USB interface of some development platforms has weak current drive capability. At this time, auxiliary power supply can be used.

Device Connection：

When evaluating and developing X4PRO under windows, X4PRO and PC needed to connected.The specific process is as follows:

Connect the adapter board with X4PRO first, then connect the USB cable to the USB port of the adapter board and the PC. Note that the Type-C interface of the USB cable is connected to the USB_DATA of the USB adapter board.

The drive current of USB interface of some development platforms or PC is not sufficient.X4PRO need to be connected to the auxiliary power supply of +5V, otherwise the lidar will be abnormal.

Installation and Dimensions

Performance Parameter

Note 1: The measurement range and relative accuracy above are the factory FQC standard value based on 80% reflectivity object.

Note 2: The relative error value indicates the accuracy of the Lidar measurement. Relative error (mean value) = (average measured distance-actual distance)/actual distance *100%, sample size: 100pcs.

Note 3: Lidar is a precision device. Please avoid using Lidar under high or low temperature or strong vibration situation, which might cause an exceeded relative error.

Electrical Parameter

Interface Definition：

X4PRO provides a PH2.0-8P receptacle interface with functional interfaces for system power,data communication and motor control.
