Apple and its posse of executives smiled brightly in front of an intimate gathering of journalists and industry insiders on Monday, touting an iPhone SE and 9.7-inch iPad Pro. But it was Liam, an iPhone-killing robot, that stole the show.

Early on in the event, Apple spent time talking about the company’s impact on the environment, and how it dismantles old devices for recycling. The one-minute video shows Liam in action as it completely deconstructs an iPhone so parts can be used in future devices and other products.

Who knew seeing an iPhone torn apart could be so fascinating?

Here’s some of the voice-over from the video:

Liam deconstructs your iPhone. Parts are detected and removed and separated, so the materials inside those parts can be repurposed. To rescue cobalt and lithium from the battery, separate gold and copper in the camera, extract silver and platinum from the main logic board, so the materials in your iPhone can live on.

According to a behind-the-scenes from Mashable, Liam, which is comprised of 29 helper robots, completes an iPhone disassembly in seconds, with 350 units turned around each hour.

The first robot removes each iPhone’s screen from the back casing. The pieces are transported via conveyor belt to another section where the battery is carefully removed. Batteries, which can be damaged or punctured during disassembly, are a health and safety issue for operators, but Liam takes the human element out of that risk.

Pieces are collected in various ways: The screws are sucked up into small tubes and are housed in a nearby container, while SIM card slots are dropped into a small bucket below the system. Each section has a small tablet display — which is, surprisingly, not an iPad — that tracks the internals of the robot and progress of the devices that pass through; if there are issues with removing a component (e.g., it gets stuck in the casing), a “failed attempt” message will show up here. Or if there’s an issue with the battery’s temperature being too high, the system will take note of it.
