Unless you're exposed to it on a regular basis, it's easy to take for granted just how advanced robotic manufacturing really is. Yet even the most advanced assembly lines still require a good bit of human interaction.

When Valve decided to design its own hardware, the company also wanted to try its hand at manufacturing. They admittedly went a bit overboard and ended up building one of the largest fully automated assembly lines in the US. Fortunately, Valve was kind enough to share it with us in the above video which outlines how the assembly line came together and how it's able to build the Steam Controller without any human interaction.
