20th Intelligent Vehicle Competition Unicycle Group Q Car Model Dedicated Integrated Side Panel PCB and Structural Open Source

This project is for the 20th National College Students Intelligent Vehicle Competition Unicycle Group Q car model design, providing a complete open-source solution, including dedicated integrated side panel PCB design and supporting 3D printed structural files.

Project Content

PCB Design

The main board integrates the TC387 minimal system and the CYT chip section for brushless drivers. To facilitate maintenance and quick replacement, the power board for brushless drivers and the brushed driver modules are designed as independent plug-and-play interfaces.

• Main board features:
  • Integrated TC387 minimal system.
  • Integrated brushless driver CYT chip section.
  • Reserved two signal interfaces and power interfaces for connecting external brushless driver power boards, supporting hot-swapping. Note: The power interface must use thick wires soldered to the main power interface.
  • Includes a complete brushed driver module.
  • Supports dual camera input.
  • Uses a six-layer gold immersion process to ensure signal integrity and power stability.
  • Power trace window design optimizes heat dissipation.
• Sub-board design:
  • Button sub-board: Used for mounting operation buttons.
  • Screen sub-board: Used for displaying information.
  • Driver sub-board: Ultra-high load capacity, supports up to 50A current load.

3D-printed structure

A series of 3D-printed structural files are provided to improve the mechanical part of the Q-car model.

• Included structural files:
  • Side panel CAD drawings (DWG format).
  • Q-car CAD drawings.
  • Display stand.
  • Magnetic encoder pad.
  • Battery protection board.
  • Other printable parts that can be used for 3D printing directly.

Scope of Application

This open-source project is intended for teams participating in the 20th National College Students Intelligent Car Competition, Unicycle Group, especially those using the Q-car model. It provides a high-performance, easy-to-maintain hardware platform along with detailed structural design to help competing teams quickly build and debug their race cars.

Notes

The TC387 minimum system on the mainboard has a bug. After burning code once on certain specific computers, it may cause permanent difficulties in burning code later, requiring repeated plugging and unplugging. After investigation, it seems to be a problem with the crystal oscillator. Please carefully check the TC387 section!!! Modify the layout or component selection at your own risk.

Instructions for Use

1. PCB Fabrication: Have the PCB fabricated and soldered according to the provided design files.
2. 3D Printing: Use the provided STL files to 3D print and assemble the car model structure.
3. Assembly and Debugging: Assemble the PCB and structural components according to the design drawings and perform system debugging.
