1. Problem/goal
In the lecture materials under the wireless track smart car training webpage, Tsinghua Cloud Disk provides the car model materials used in the competition. You can download relevant data files from the cloud disk, and have a deeper understanding of some electronic modules and test software used in smart cars. Let me introduce to you the contents of these materials. It is convenient for everyone to learn.

2. Data content
Everyone clicks on the Tsinghua network disk data download in the training webpage , you can open the network disk link and enter the LongQiu directory. Four of these files can be seen. (1) The compressed file of the dual-regulation wireless charging line patrol car includes the documents of the main electronic components and debugging software in the car model. (2) The compressed file of the initial sports car program contains three MicroPython programs, which are the test programs that have been burned inside the car model. Their use is introduced in the training materials, about how to download the sample program for the car model, let the car model run This blog post is introduced. (3) The relevant information on the installation of the double-track energy-saving trolley provides some instructions and precautions for the installation. (4) The overall video of the mechanical installation of the car model, which shows a complete demonstration video of the mechanical structure of the car model installed. In the following, I will introduce the contents of the first compressed file. For the rest of the files, you can download and understand them yourself.
Click to download the first compressed file. Copy the downloaded file to a temporary unzipped directory. Unzip the file. This is the document in the unzipped directory. There are 9 directories in the front, which respectively contain the development software environment, the information of each circuit board and the test Python code. Followed by three demo videos and some explaining Word documents.

In the first directory, the installation software under Windows downloaded from Thonny's official website is stored. You can install the Thonny development environment on your computer. The second directory stores ESP32 MicroPython firmware files, which are used to update the ESP32 MicroPython firmware on the main control circuit board. You can learn and use the content in the above two directories according to the blog posts in the use of training software. In fact, they can all be downloaded directly through the Internet, so they are not used. The information about the ESP32 motherboard in the third directory is very important, and the circuit schematic diagram of the main control board is given. Some of the content will be mentioned later in the training video, and you can see the circuit details of the main control board from this PDF file. The fourth and fifth catalogs respectively contain the contents of the motor drive board circuit and the electromagnetic signal amplification and detection circuit. You can consult the design documents in these two directories according to your ability and preference.
The sixth directory contains modules that test short MicroPython programs that are used in the training material Hardware Learning Videos. The comprehensive sports car code in the seventh directory gives some sample programs for car model control. Through these codes, you can understand the entire program control framework and learn the method of MicroPython programming. The eighth directory provides information on obstacle avoidance, including information on photoelectric sensors for obstacle detection and ideas for obstacle avoidance. You can design and complete the program of the competition subject 3 by studying the files in this directory. The ESP32 datasheet is given in the last directory, and the description of the ESP32 pins not included in the schematic can be found in its datasheet. Let's browse the contents of each directory in the data package, and you can quickly find the required materials when you need them later.
Regarding the documents behind the development materials, including demonstration videos and introductions to wireless charging cars, you can watch and read by yourself. No more introductions will be made here.
3. Practice/Experiment
This article introduces the contents of the smart car learning materials. I hope that everyone will have a general understanding of these materials as soon as possible, so as to lay the foundation for the subsequent car model debugging.
