My DIY Segway Project

This entry is part 1 of 3 in the series DIY Segway  

The goal of this project is to create a self-balancing robot that I can actually ride!

The early stages of the project and I'm already changing out the drive train.  Note new motors.

The brains behind this segway is an Atmega328 microcontroller using a complementary filter algorithm (Accelerometer and Gyroscope readings are combined to create a more accurate pitch and momentum reading).

I have assembled the drive train but I believe the motors I have chosen are going to be too slow to catch momentum swings.  I ordered 2 new 24V scooter motors to replace them.  Since the mounts are different, I have to rebuild the chassis as well.

Another setback I have recently experienced is burning out my MOSFET motor driver.  It actually wasn’t the MOSFET that failed…It was my etched PCB.  I obviously had too thin of traces for that kind of current.  I have redesigned but will need to go through the etching process…again!
