How to Make an OwlBot: The Bird Intimidator - Part 5: Mechanical Movement

This is the fifth video (Part 5) of a series of tutorials on how to build an OwlBot.

In this project we’re going to be performing the next step of what will eventually be the OwlBot. The OwlBot will be a device (robot/animatronic) that can be used as a bird intimidation tool to scare away pesky birds in the yard, around the house or barn, at restaurants, or in trees, bushes, and gardens. Hence, the phrase, “The Bird Intimidator”.

During the prototype process of making the OwlBot, I will be using the help of a previous project that was built, The Ultimate DIY 3220-Point Breadboard (TUDIY), to help in the prototyping process. I've provided the links to this project below. If you didn't make your own 3220-point breadboard, then don't worry! You can use just about any ole' generic breadboard you got laying around and still participate in this project. You can obtain everything you need to follow along on this build at the given links below.
