DIY 3D-Printed RC Rover

Compact Remote-Controlled Rover

This small remote-controlled rover started as a fun project I wanted to build and improve over time. At its core, it’s a simple box on wheels, powered by several Li-Ion batteries. The idea is to make it easy to add different parts and features as needed.

One of the setups I’m working on is made for exploring around the house while getting a clear video feed. I’ve mounted an old Windows PC on the rover, connected a few USB cameras, and used OBS Studio to arrange the video on my screen. It connects over Wi-Fi, so I can drive it from my computer.

In OBS, I set up the camera views to feel like driving a car. The main camera shows the front view, the rear camera is placed at the top of the screen like a mirror, and I plan to add a third camera on a small pan-tilt mount so I can look around without turning the rover. It makes driving much easier and more fun—especially if you’re just learning how to control something remotely.

Purchased components:

Takanawa 555 gear motors qty 4

8mm flange coupling connector qty 4

Sabertooth dual motor driver qty 1

18650 battery holder qty 6 (used for 6S4P configuration Li-Ion battery pack) 

Panasonic NCR18650B qty (at least 6. I used 4 in parallel, 6 in series so my pack is 24 cell)

They are very expensive these days, you can pick an equivalent. 

24V BMS (BMS-battery management system)

.250"x.375" silicone rubber plugs qty 48 per wheel 

XT60-EF connector qty 3

On-Off rocker switch qty 2

Please keep safety in mind! If you're not familiar with building a battery pack, consider purchasing one that fits the chassis after motor installation.

Printed parts:

4" wheel hub qty 4

wheel inner ring qty 4

motor mounting plate qty2

RC utility rover chassis qty1

The assembly process is relatively simple. Based on the interest generated by the project, I will add more detailed information.

I printed all my mini RC components using ASA filament, except for the cover, which is made of PETG.

Assembling the wheels can be a bit tedious, involving pushing and pulling silicone plugs. However, these wheels offer excellent grip on grass and rocky terrain, with the silicone plugs providing cushioning and shock absorption. If you successfully build these wheels, please share your results. I might update the document with additional information, but documentation takes time. Without interest in this project, there's no reason for updates.

The wheels provide excellent traction on lawns. Check out these mini mower prototype videos showcasing some designs:
