DB1 - Build a REAL RobotIntroducing DB1, a REAL Robot that I am building. And you can follow along and build one too!

DB1 is a complex project and it will take some time to build. Each week I’ll show you my progress with a new article and video.  This is not your typical “robot car base” robot. This is a robot capable of becoming aware of its environment and “learning” tasks you assign to it.

Along the way we will be dealing with a number of different disciplines:

  • Mechanics – We are building the robot base from scratch. You’ll learn to construct the base, how to select motors and wheels and how to assemble it all.
  • Electronics – There will be a myriad of electronic components in DB1. Sensors, microcomputers and microcontrollers, and a lot more.
  • Programming – A great deal of programming will be involved to make DB1 come to life.
  • Machine Intelligence – You will learn advanced machine and artificial intelligence techniques as we create our robot.
  • Advanced Sensors – From video cameras and microphones to LIDAR, DB1 will employ a number of advanced sensors to explore the world around it.

Despite all of these advanced capabilities, DB1 will employ parts that you can easily get hold of. So you can duplicate my work, or use it to create a robot of your own unique design.

So please join me as I create a REAL robot.  You can read all the articles here and see all the videos on YouTube.

 

Build a Real Robot Part 1 - Introduction

Introducing DB1, a "real" robot project that you can follow along and build.

In this introduction to the project I will go over the main features and "layers" that DB1 is composed of. You will also get an idea of how the project will evolve.

Build a Real Robot - Part 4 - Selecting Wheels

In the fourth installment of the Build a REAL Robot series I will discuss wheels. While it may not seem like the most thrilling subject, selecting wheels for your robot is a very important task.

I will discuss some of the specifications you will need to know when selecting robot wheels and I'll also go over the different types of wheels you can use for your robot.

Build a Real Robot - Part 5 - Base Electronics

In part 5 of the "Build a Real Robot" series I will show you the electronic modules that are mounted on the base unit of DB1.

One of the modules, a Raspberry Pi 3B+, may not be exactly perfect for the job! I will explain why we are using it now, and why it might get replaced with another microcomputer at a later date.
