MIT researchers built a robotic laboratory that assembles and runs optics experiments by itself. A robotic arm picks up mirrors, lenses and light sources held in 3D-printed housings. Each housing carries a QR code describing the part inside, and a magnetic base holds it in place. Overhead cameras and control software let the robot place parts and avoid collisions. A clip-on motorised tool turns adjustment knobs over Wi-Fi to angle components precisely. The robot assembled a working laser cavity using 50 moves in half an hour. It also re-aligned itself after researchers disturbed parts on the table. A simple interface lets a person drag a component icon and have the robot move the real part. The team is now building cloud access so scientists can submit experiments remotely. They are also using the system to test materials that capture carbon dioxide.
What changed
Optics setups were assembled and aligned by hand, taking days to months.
What it unlocks
Building, aligning and dismantling a tabletop optics experiment without a person present.
- 50 maneuvers in 30 minutes
- robot arm with 7 joints
- micron-scale tuning precision
What you need to act on it
- research lab with the robotic hardware
- cloud access still in development
