3.Main Composition and Interface Description

3.1 Main Composition

The LubanCat Main Control Box consists of three parts: the RK3588 Core Board, the RK3588 Base Board, and the Power Board plus IMU.

（1）Robot Main Control Box - RK3588 Core Board

The core board is equipped with an eight-core CPU processor-RK3588 with four-core A76+ and four-core A55. It has a powerful GPU and a built-in NPU with 6T computing power. In addition, the core board is also equipped with large-capacity eMMC and DDR chips, and the maximum external peripherals of the chip are realized through BTB pins.

（2）Robot Main Control Box - RK3588 Base Board

It features a separate core board design, providing abundant connection options and expansion interfaces. Such as multiple USB ports (USB 2.0 and USB 3.0), an HDMI output interface, a TF card slot, a Mini-PCIe socket supporting 4G or WiFi, as well as a Type-C interface, a Debug serial port, and audio input/output ports. It supports a variety of peripheral connections and debugging functions, making it an ideal choice for developers engaged in hardware design and software development.

（3）Robot Main Control Box - 7-Channel CAN - Power Board

The 7-Channel CAN - Power Board is specifically designed for high-efficiency power and communication applications. It receives 48V input through an XT60 (2+4) power interface and provides 2 Debug serial ports for convenient debugging and development. The board includes 7 XT30 (2+2) interfaces for power output, etc., and supports 12V voltage output to supply power to the carrier board. In addition, the board is also integrated with one IMU module and one debugging interface, ensuring diversified function expansion and a stable power supply system.

4.Software and Driver Environment

• Recommended System Environment (e.g., 04)

It is recommended to use the Ubuntu system (Ubuntu 20.04 system) that comes pre-installed with the product, along with the configured ROS environment (Noetic).

• Install Drivers/Dependencies

If using the official SDK requires configuring the ROS environment (Noetic), a serial communication driver must be installed, and the commands are as follows:

sudo apt-get install libserialport0 libserialport-dev

• Development Environment Used

Such as ROS1 (Noetic), CAN Debugging Tools, Serial Port Assistants, etc.
