A durable, 3D printed, remote controlled Arduino based robot with several hundred meters range. A modular quick-connect motor scheme lets you rapidly prototype different robot designs without any tools. Perfect for robotics education for kids.
Whats it all about?So you’ve just started learning Arduino, or maybe 3D printing and your ready to build something cool. You want to build something meaningful, and practical, but fun… You’re ready to build the OmniBot. If the Arduino is the Swiss Army Knife of electronics, then the OmniBot is the Swiss Army Kife of robotics! The OmniBot is the result of a several month long project of Bolts and Bytes Maker Academy that aimed to design a versatile and easy to use remote controlled robotics kit. And now its all open source! The OmniBot is battery powered, can drive up to four DC motor channels, two servo motors, and has a remote controlled range of several hundred meters! And it all fits inside a sleek 3D printed case, running on, you guessed it, an Arduino Uno brain.
Okay, but why?We really wanted to make it super easy for young kids to pick up some cardboard and glue and end up with a working custom robot. With traditional robot kits you might buy online, you’re forced to deal with lots of messy jumper wires, writing your own code, and - oh yeah… you can almost never control them remotely. They just run the same code in a loop. With the OmniBot, you simply plug in a battery, plug in a motor, and tape it or glue it where you want, and - boom. robot. All the code we’ve written auto-magically works with the same controller you might use for a drone or RC plane. It’s the perfect kit for rapid prototyping field ready robots. When you have finished building your OmniBot platform, you have only just begun. In ten short minutes you could go from a mission critical bomb defusing robot, to a Rocket-league style soccer bot, and that’s what makes OmniBot powerful. So let’s get started!
Recommended Skill Levels:
This projects includes some light soldering, it is fairly manageable for beginners.
General understanding of Arduino and how to work in the Arduino IDE uploading sketches and adding libraries. No coding is required but advanced users can customize their code if desired.
Some light hardware work with screwdriver and wire cutters/strippers. Adult supervision recommended for young kids. (The final product is suitable for use with all ages!)
Required Tools:
Soldering iron and solder
Allen wrench/key or hex head screwdriver
Phillips head or flat head screwdriver (depending on the terminal blocks of the motor shield)
Hot glue gun and hot glue sticks (not required but highly recommended!)
Wire cutters (flush cutters are recommended as they can be used in other steps)
Wire strippers
Needle nose pliers (not required but it makes cleaning the 3D print much easier)
Access to a 3D printer (if you don’t have one, ask your local maker space, school, lab, or library!)
A computer with the Arduino IDE software
Bill of Materials:
The following items and links were sourced from Amazon (all or most are Amazon Prime items) but it should be noted that most, if not all of these, can be found for much cheaper on websites like Banggood and AliExpress if your willing to wait a few weeks for shipping. This can actually cut the project cost in half if you look well enough.

Arduino Uno Microcontroller (the type with the surface mount chip works better for this)
Arduino Motor Shield V1
Turnigy Evo Transmitter (mode 2) (this one comes with the receiver but most receivers with iBus communication should work)
Male and Female JST plugs (I highly recommend the type with silicone because they are more flexible)
13.5mm x 9mm Rocker Switch
M3x6mm countersunk screws (only 6 screws are actually needed)
2S Lipo battery (this can be substituted with a non rechargeable battery back between 7 and 12 volts)
2S Lipo Charger (only required if using a lipo battery)
PETG 3D printer filament (PLA can be used but PETG is more durable and heat resistant to hot glue)
TT motors and wheels
Servo motors (larger servo motors can be used as well)
If you’ve got all your tools and parts then follow me! We’ve got robots to build…”
