Circuitmess Wheelson User manual

Introduction
The beginning
Welcome to CircuitMess Wheelson build
guide!
By following this build guide, you'll learn how to assemble your very own AI self-
driving car.Autonomous cars are the future and we’ll show you how they work. With
Wheelson you'll learn about microcomputers, autonomous driving, computer
vision, and much more.
Check out the anatomy guide before you start to learn
more about the components you're about to
assemble.
Wheelson's anatomy guide is a great addition to this guide that will explain all the
components on Wheelson's main board in more depth.
You can check it out here!

Age group
Like it says on the box, Wheelson is designed for anyone who's at least 11 years old.
Some of the assembly steps should be approached carefully, so make sure to have
an adult jump in if you need some help with soldering or tightening the bolts later
in the process. It's okay to ask for help.
Don't worry though! We'll go through the assembly step by step and provide some
useful tips along the way. We'll give you a heads-up if there's something important
to keep in mind while assembling.
Assembly time
It should take you approximately4 hours to fully assemble your Wheelson.
Of course, the assembly time depends on your previous knowledge and
experience. If you don't have any experience yet, don't worry! It just might take you
a little longer to get into the groove and overcome the challenges in the beginning.
Skills
You don't need to have any specific skills before getting your hands dirty with this
DIY project.

The main objective here is to have fun and learn something new.
So hold on tight, read all the instructions, and get ready to have fun! This is a great
opportunity and your first step in your big engineering career.
Learning with Wheelson
As previously mentioned, Wheelson will teach you a few useful things along the
way.
Here's what you will learn:
How to assemble a small 4-wheeled robot (that's Wheelson!)
How to control an electromotor using a microcomputer
How computer vision works
How to calibrate your robot’s camera
How autonomous cars work and how they navigate a road autonomously
How to recognize and scan a QR code using your robot’s camera
How to recognize different simple objects using a camera and image
processing algorithms
That Tesla’s engineers are not some crazy magicians
What's in the box?
Let's get to know all the components that
come in the box!

Open your Wheelson box and check if you have all the components. Make sure to
lay it all on a clean surface where you can inspect if everything is there according
to the photo and the list below.
In case something is missing, please contact us at [email protected].
Send us a photo of everything that came in the box, and we'll get back to you as

soon as possible to resolve the issue!

Meet the tools
Mandatory tools
In this chapter, we'll explain what tools you'll need to assemble your Wheelson!
If you have your CircuitMess Tools pack in front of you, you should be all set.
In case you got the Wheelson kit without the Tools pack, this is a good time to
borrow some of the tools or purchase them.
The tools required are essential when assembling, fixing, or modifying electronic
devices! These are the tools of the trade for every maker/hardware
hacker/modder/electrician.

1. Soldering iron
2. Desoldering vacuum tool (solder sucker)
3. Soldering iron stand
4. A small reel of rosin-cored solder
5. Cleaning sponge
6. Phillips screwdriver
7. Diagonal cutter pliers
8. Needle-nose pliers
Soldering iron
A soldering iron is the most important tool in a maker’s arsenal.
For Wheelsons assembly, any entry-level soldering iron will suffice.
If you plan to dive into the world of DIY, you should maybe consider getting a more
expensive soldering station with temperature regulation.
There are also many soldering irons with interchangeable tips that can be
particularly useful when working with much smaller components.
You will find the instructions on how to properly solder and take care of your
soldering iron in the next chapter.

The soldering iron from the Tools pack
Diagonal cutter pliers
With pliers like these, you’ll be able to trim the legs of soldered components and
cut wires!
We prefer this type shown in the picture (Plato, model 170), but any other type will
do.

Soldering sponge
This small piece doesn't seem like much until you soak it in some water. It then
turns into a super solder-cleaning sponge!Use it after soldering a couple of
joints to remove the excess solder from the tip of your iron. Make sure that the
sponge isn't dripping wet or bone dry - it should be damp.

Diagonal cutter pliers
Needle-nose pliers
You’re going to need pliers like these when assembling the casing, or when
plugging in some tricky connectors!
They’re generally useful when doing some fine mechanical work.
