Introduction
The PiCar-V is an open source robot learning kit on Raspberry Pi. Equipped with a wide-angle USB webcam, it is powerful together with three whole new circuit boards with less but simpler wiring, some acrylic plates in a well-designed structure, and complete code suitable for almost all platforms to control the car. Python code is provided for the car, and you can also program and debug it with Dragit, a Snap-based graphical interface, by just simple dragging and dropping the code blocks for complex function. There are many ways to control the robot remotely: with the app on PC (works on any OS), you can control the car and the cam’s direction on the UI and view the image it takes in real time; or, with the related code, realize the same functions on a web browser, meaning it works with any mobile phones, tablets, etc.
