How to make and program a robot??

There are lots of different ways to build a robot, and what you'll often find is that tutorials and books sometimes give you a lot of info on electronics, different programming boards etc. which is all great, but do you really need to know all of that before you get started? Nope.

So here, we are presenting a fun guide, on how to build your first robot.

We will get straight to the point and hopefully you will be up and running very quickly.

Together we will build a 2 wheeled robot.

You will learn how to put it together and a little bit about how it works.

From there you will be able to explore further and when you are ready you can learn in detail about the electronics and programming behind it.

STEP 1: BUILD A BASE/PLATFORM or CHASSIS

To get started you need a base with motors and 2 or 4 wheels.

Below we have listed a few ideas.

You can of course find your own, please make sure it is strong and sturdy and servo motors will be easier as you won't need extra motor drivers.

Simple, 2 wheeled Robot Chassis

These usually come with a supporting wheel and motors.

It isn't the strongest, but it is fairly sturdy  - for example it won't survice a fall of a desk...not that we know about that ahem... but its good enough for a basic robot driving around your bedroom floor for example.

Expect to pay around £8 - £15 for one of these.

Motors and battery holder is included.

Simple, 4 wheeled Robot Chassis

This is similar to the 2 wheeled chassis above, but comes with 4 motors. 

This gives you the option of different drive options, i.e. 4 wheel drive, back wheel drive etc.

This kit also comes with battery holder and a double layer chassis, so more space 

for parts.

Expect to pay around £16 - £20 for one of these.

Stronger, 2 wheeled robot chassis

Similar to the first chassis, but this one is made from aluminium and comes in a gorgeous colour.

Check if motors are included before purchasing from your retailer.

Expect to pay around £15 - £20 for one of these.



A more robust, 4 wheeled Robot Chassis

Perfect if you are looking for something more monster truck style - we like this one :)

This chassis is made from iron, so perfect for those cazy obstacle courses and jumps that you want your robot to fly through.

It comes with a battery holder and 4 DC motors - so you will need a motor driver, which we will explain shortly.

Expect to pay around £80 - £100 for one of these



For Tank Fans

Although we don't usually recommend these for beginners, but we wanted you to know what options are available.

This tank track chassis is very cool and comes with motors and a speed feedback circuit.

Its made from Aluminium so perfect for games of war!

Expect to pay around £50.



STEP 2: FIND POWER AND A BRAIN

We need power and a brain for the robot. In another guide we will look into detail on how you go about choosing these two things, but for now lets look at getting something working.


You will need a battery holder and 4 AA batteries for a power source.


Attach it to your chassis.


Step 3: Find a brain. What this means is you need to find a programmable board that lets you control motors, leds, buttons etc.


There are some different options which we will look at in part 2, for now, we are going to choose Arduino. It is cheap, and has all of the functions we need, its also super easy and quick to set up. 

It shouldn't cost you more than about £20.


An arduino Uno is fine, if you are planning on doing large projects in the future than an Arduino Mega is also ideal.
