I recently had the opportunity to create a version of MetalHead from one of my favorite episodes of Black Mirror. The idea of drones that can kill you with impunity is pretty terrifying. Real life drones like Metalhead are almost here, unlike the T-1000 from The Terminator, these "robo-dog" with the capability to kill you is frighteningly close. Simply google Darpa or Boston Dynamincs robot dogs and you are inundated with videos on the advancements of these robotic systems.
Now, don't get me wrong, these robotic systems are very cool and the amount of good they can do is out of this world. However, one of the great aspects of the Black Mirror series is show us what can happen if technology gets out of control. Thankfully, killer robot dogs are still relegated to the world of science fiction.
Take a look at the progress of the 3d modeling and rendering.
After I handed the "official" 3d model in to the client, I added some color of my own, some American flags and of course a LOT of weathering.
