PiDog is a Raspberry Pi pet robot with aluminum alloy structure. It can act as a mechanical pet, show cuteness to you,
and interact with you.
It is equipped with a camera module, which can perform color recognition, face detection and other projects; 12 metal
gear servos support it to walk, stand, sit, shake its head, and pose in various poses; The ultrasonic module on the head
enables it to quickly detect obstacles ahead; Special touch sensors allow it to respond to your touch; The Light Board
on the chest can emit colorful light effects, and with the speaker equipped with the robot HAT, PiDog can express
emotions such as happiness and excitement. In addition, PiDog is also equipped with a sound direction sensor and a
6-DOF IMU module to realize more complex and interesting usage scenarios.
If you have any questions, please send an email to [e-mail] and we will respond as soon as possible.

ASSEMBLE VIDEOS
Before assembling the PiDog, please first verify that all parts and components have been included. If there are any
missing or damaged components, please contact SunFounder immediately at [e-mail] to resolve the
issue as soon as possible.
Please follow the steps on the following PDF for assembly instructions:
•Component List and Assembly Instructions.
Mount Raspberry Pi Zero W on PiDog
If your mainboard is a Raspberry Pi Zero W, here are the steps to install it on the PiDog.
Afterward, you can continue following the instructions in the video below from 2:28 onwards to assemble it.
Assembly Tutorial Video(Raspberry Pi 4/3/1 Model)
This video will walk you through the process of assembling your robot from scratch.
In this tutorial, you will learn:
•Preparation: We’ll introduce you to all the tools and parts needed, ensuring you’re fully equipped before starting
the assembly.
•Assembly Steps: We’ll demonstrate each assembly step in a systematic manner.
•Tips and Considerations: Throughout the process, we’ll share essential tips and tricks to help you avoid com-
mon mistakes and ensure your robot operates smoothly.
•Zeroing a Servo: Before fixing each servo, it needs to be zeroed first. The steps for zeroing are to first install
the Raspberry Pi OS, then install the required modules, and then run a script (set the angle of all PWM pins to
0). After that, plug in the servo wire to zero the servo.
The assembly process for Pidog is quite long, so we have divided it into two videos. The first video covers assembling
Pidog’s body and four legs.
The second video covers assembling the head and calibration.

PLAY WITH PYTHON
If you want to program in python, then you will need to learn some basic Python programming skills and basic knowl-
edge of Raspberry Pi, please configure the Raspberry Pi first according to 1. Quick Guide on Python.
2.1 1. Quick Guide on Python
This section is to teach you how to install Raspberry Pi OS, configure wifi to Raspberry Pi, remote access to Raspberry
Pi to run the corresponding code.
If you are familiar with Raspberry Pi and can open the command line successfully, then you can skip the first 3 parts
and then complete the last part.
2.1.1 1. What Do We Need?
Required Components
Raspberry Pi
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard
keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how
to program in languages like Scratch and Python.

Power Adapter
To connect to a power socket, the Raspberry Pi has a micro USB port (the same found on many mobile phones). You
will need a power supply which provides at least 2.5 amps.
Micro SD Card
Your Raspberry Pi needs an Micro SD card to store all its files and the Raspberry Pi OS. You will need a micro SD
card with a capacity of at least 8 GB
Optional Components
Screen
To view the desktop environment of Raspberry Pi, you need to use the screen that can be a TV screen or a computer
monitor. If the screen has built-in speakers, the Pi plays sounds via them.
Mouse & Keyboard
When you use a screen , a USB keyboard and a USB mouse are also needed.
HDMI
The Raspberry Pi has a HDMI output port that is compatible with the HDMI ports of most modern TV and computer
monitors. If your screen has only DVI or VGA ports, you will need to use the appropriate conversion line.
Case
You can put the Raspberry Pi in a case; by this means, you can protect your device.
Sound or Earphone
The Raspberry Pi is equipped with an audio port about 3.5 mm that can be used when your screen has no built-in
speakers or when there is no screen operation.
