Self stabilizing robot

This self stabilizing robot that I designed is a great handheld robot that uses a counterweight to keep it's head upright at all-times. This is also a great educational model as it helped me understand how counterweights can help balance something no matter how the main object is moving. In my opinion, counterweights are a great proof of concept and I encourage my users to incorporate this in their own models.Please note that you can but don't have to make the counterweight heavier.This model was hugely inspired by the STYR-01: The Self-Stabilizing Rolling Robot Judhini Prints on Printables designed. I really enjoyed and liked this user's model and had a great time with it. This is a link to his model:https://www.printables.com/model/1194641-styr-01-the-self-stabilizing-rolling-robot/comments
