Worlds Smallest Balancing Robot? MiniPIDDY

Pushing the limits of tiny robotics - MiniPIDDY is a miniturized version of my PIDDYbot - a Self Balancing Robot.

Similar projects worth following
One of my first projects was a self balancing robot that used an IR sensor to determine its upright position. It was featured on HaD long ago and was actually smaller that this guy. This one, however, is much better at balancing. Simply put, board consists of a ATMEGA32u4 a MPU-6050 and a motor driver. The body is 3D printed, and the motors are tiny little 26:1 geared motor. It uses a PID control strategy to balance. Its the ultimate desk toy. There is bluetooth, but I don't like the module I chose, going to change it to something more simple.

Enjoy this project?

This should tide you over until I make a better video.

Looks like the tiny wheels and motors pololu sell.

Not ridiculously cheap but not overpriced either!

Though there's a big warning about not stalling the motors so not sure if this is really the right application for them! Perhaps with current limiting it'll be OK...

This is a very nice robot! All it misses is a pair of goggly eyes and some hair!

  Are you sure? yes | no
