At the request of several viewers I’m launching a Mini-bot project this week. The goal of this project is to provide a basic guide on how to go about building a small robot from scratch. There are many sources for parts for a robot and for this one I chose Pololu. They offer parts as well as robot kits at reasonable prices.
For this project I chose the smallest components I could find. The micro gear motors are an amazing piece of hardware. It’s incredible that there is a planetary gear transmission inside the 5mm diameter housing! The micro controller I chose is about the size of a postage stamp and the motor driver board isn’t much bigger. This allows for a final assembly that will fit on a small perfboard.
In part 2 I’ll post a wiring diagram and a parts list.
Keep on hackin!
