Description

I've been working on this project for one year as a hobby project. The Metalhead Dog is a robot dog from the Black Mirror series S04E05."Metalhead" is filmed entirely in black and white, and follows the plight of Bella (Maxine Peake) trying to flee from robotic "dogs" after the unexplained collapse of human society.

My initial goal was just to make It stand on It's feet and use some sensors like ultrasonic, gyro, pir, temperature and hummidity, but now I want more. I'm happy with the results until then and would be glad with opinions and tips about this project. Here is a video where I'm testing the leg motors:
