Introduction
Welcome to the world of STEAMbot robot kits! We at The STEAM Train want to thank you for
getting a STEAMbot robot kit. We believe that any child that wants a robot should be able to get
one, no matter their socio-economic background. This kit will help you learn more about
Science, Technology, Engineering, Art, and Math (STEAM). We hope you will have lots of fun
putting your robot together and learning how to program it. Your efforts will be rewarded and
give you opportunities for a better future.
This guide has the following chapters:
1. Assembly of Your STEAMbot – provides the steps of how to assemble your STEAMbot
robot.
2. Connectivity – describes how the STEAMbot communicates over a WiFi network.
3. STEAMbot Home Page – describes the home page of the STEAMbot. Via the home page
you can control your STEAMbot, change the operating modes of your STEAMbot, ,
mange the WiFi networks it connects to, calibrate the motors of your STEAMbot, update
the firmware of your STEAMbot and finally, you can program your STEAMbot.
Why Robotics?
When you learn about robotics, you will learn about the following fields:
• Mechanical engineering – how is the robot designed to mechanically work together and
make sure all the parts fit and not fall apart.
