Welcome to PiCar-X’s Documentation!

Thanks for choosing our PiCar-X.

The PiCar-X is an AI-driven self-driving robot car for the Raspberry Pi platform, upon which the Raspberry Pi acts as the control center. The PiCar-X’s 2-axis camera module, ultrasonic module, and line tracking modules can provide the functions of color/face/traffic-signs detection, automatic obstacle avoidance, automatic line tracking, etc.

PiCar-X has two programming languages: Blockly and Python. No matter what language you program in, you’ll find detailed steps to teach you everything from configuring the Raspberry Pi to running the relevant example code.

• Play with Python

  • This chapter is for those who enjoy programming in Python or want to learn the Python language.

  • To get Picar-X working properly, you must install some libraries first.

  • The Raspberry Pi configuration and samples code for the PiCar-X are provided in this chapter.

  • An APP - SunFounder Controller is also provided to allow you to remotely control the PiCar-X on your mobile device.

• Play with Ezblock

  • In this section, you will use a Blockly based APP, Ezblock Studio, which, like Scratch, allows you to drag and drop blocks to make Picar-X move.

  • It is required to reinstall the SD card with the operating system we provide with pre-installed Ezblock environment before programming. It is recommended to use a new or unused TF card for this section.

  • Ezblock Studio is available for nearly all types of devices, including Macs, PCs, and Androids.

  • Ezblock Studio is a good choice if you are 6-12 years old, or don’t have programming skills, or want to test Picar-X quickly.

About the display language

In addition to English, we are working on other languages for this course. Please contact service@sunfounder.com if you are interested in helping, and we will give you a free product in return. In the meantime, we recommend using Google Translate to convert English to the language you want to see.

The steps are as follows.

• In this course page, right-click and select Translate to xx. If the current language is not what you want, you can change it later.

• There will be a language popup in the upper right corner. Click on the menu button to choose another language.

• Select the language from the inverted triangle box, and then click Done.
