SunFounder GalaxyRVR Kit for Arduino, Release 1.0
Imagine piloting a rover on the desolate terrain of Mars, exploring alien landscapes and confronting the unknown.
Sounds like a dream for NASA engineers, right?
Not anymore.
Welcome to the world of the GalaxyRVR, a Mars Rover kit from SunFounder, designed to bring interplanetary explo-
ration right into your living room.
Built upon the same universal rocker-bogie system employed by NASA’s real Mars rovers, GalaxyRVR is capable of
traversing all kinds of terrains – be it rocky mountains, sandy beaches, or grassy fields. The suspension system ensures
smooth mobility, making the alien world of Mars feel just like home.
Equipped with a high-definition camera module, GalaxyRVR offers a first-person view, providing an immersive piloting
experience as if you’re truly navigating the Red Planet. Its advanced obstacle avoidance module and ultrasonic module
ensure it can dodge obstacles, embodying a spirit of autonomy and resilience.

ASSEMBLE VIDEO
Note:
•If you want to learn while assembling the various components, you can refer to Course Mode. In Course Mode,
each lesson comes with assembly videos, component principles, and related test code, allowing you to learn as
you go. So, you can skip this chapter.
•If you want to quickly assemble and start playing, you can watch the assembly video first. After completing the
assembly, proceed to Play Mode to learn about the app installation and connection. Then, you can use the app
to control the GalaxyRVR.
For the assembly of the GalaxyRVR, we provide printed assembly instructions in the kit. Here is the PDF version of it:
If you are having difficulty understanding the printed assembly instructions, you can instead follow our step-by-step
assembly video.
Note:
•The assembly videos are in a series of 7. You can check out other videos from the playlist in the upper-right
corner, or let it play automatically.
•When inserting the ESP32 CAM into the Camera Adapter, be aware of its orientation. It should align properly
with the ESP32 Adapter.

PLAY MODE
Are you eager to kick-start your Martian journey right away? Our Play Mode is perfectly tailored for those of you who
just can’t wait to dive in. Equipped with factory-preloaded code, you can jump straight into the action after assembling
your GalaxyRVR. Use the user-friendly SunFounder Controller app to explore its myriad of functions including first-
person driving, switching between obstacle avoidance and follow modes, and even voice control.
But before you set off to explore the Red Planet, let’s make sure you are fully equipped and ready for the adventure.
Below is a Quick Guide to assist you in this exciting journey!
Note:
•If your R3 board has already been uploaded with other code, but you want to continue using Play Mode, you will
need to download the relevant code.
–GalaxyRVR Codes
•Then, open the galaxy-rvr.ino file located in the galaxy-rvr-main\galaxy-rvr directory.
•Move the switch to the right and then click Upload.

2.1 Quick Guide
1. Let’s start the GalaxyRVR.
•If it’s your first time using the GalaxyRVR or if the battery cable has been unplugged, the GalaxyRVR Shield
will engage its over-discharge protection mechanism. To deactivate this protection, plug in the Type-C cable
for approximately 5 seconds. If the power indicator lights up, the protection status has been released. Check
the battery indicators – if both are off, please continue charging the battery using the Type-C cable.
•To activate the ESP32 CAM, move the mode switch to the Run position, and press the reset button to
reboot the R3 board. You will then observe a cyan light flashing on the bottom strip.
2. Install SunFounder Controller from APP Store(iOS) or Google Play(Android).
3. Connect to the GalaxyRVR Network.
For optimal communication between your mobile device and the Rover, you’ll need to connect them
to the same local area network (LAN) provided by GalaxyRVR.
•Find GalaxyRVR on the list of available networks on your mobile device (tablet or smartphone),
enter the password 12345678, and connect to it.
•The default connection mode is AP mode. After you’ve connected, there might be a prompt
warning that there is no internet access on this network. If so, choose “Stay connected”.
