Robot Chassis

Pronounced "Chass-sey". This is the main body of your robot. Each of these was designed by an e3 Scholar in a 3D CAD program, and 3D printed just for the Battle of the Bots.


DC Gear Motors (2)

These are the motors that we will use to make our bot move. They are DC (Direct Current), which means that we can make them turn with a battery. The big yellow part is a "gear box". This makes the motor slower, but gives it the power that we need to turn the wheels.


Wheels (2)

These are designed specifically for the motors that we are using. Some of them have different sizes, so make sure that yours match!


Swivel Wheel

This wheel will change direction to allow your bot to go whichever way you want. It also helps the bot balance.


Arduino Nano

This is the "brain" of your robot. You will connect this to a computer and write code to tell your bot how to move its wheels. But it can do a lot more. When you get home, look around for more projects with Arduino!


Mini Breadboard

The mini breadboard will serve two purposes. First, it will hold onto our Arduino Nano. Second, it will allow us to make electrical connections just by plugging wires into the slots. Keep scrolling to see how this works.


Underneath the plastic, there are strips of copper that conduct electricity. So if you plug into a slot, the four other slots in the same row will all be electrically connected to each other. That way we can connect the battery to everything that needs power, and the Arduino pins to the motor controller.


Motor Controller

The Arduino is smart, but it can't do much heavy lifting on its own. So the Arduino tells the motor controller how the motors should move, and the motor controller handles the higher voltage and current.


9 Volt Battery Holder

Finally, you just need something to hold the battery that powers the bot. This case has an On/Off switch that will be pretty handy. The red wire is the positive voltage and the black one is what we call "Ground" (GND).

IMPORTANT: Do not connect the red and black wires together. This will create a "short circuit". It will get really hot and the battery will drain the battery super quickly. So we could run out of batteries or even start a fire. Don't try it.
