MIT Team Builds Reconfigurable Robotic Lab for Automated Optical Experiments

Researchers at the Massachusetts Institute of Technology (MIT) have developed a reconfigurable robotic optical laboratory that can autonomously assemble standard optical components into desired configurations, adjust mirrors and lenses with micrometer-scale precision, and safely disassemble and reassemble experimental setups.

The system uses a seven-axis robotic arm mounted on a metal table. Each optical component is fitted with a 3D-printed plastic housing marked with a QR code, which the robot scans to identify the component. A Wi-Fi-enabled fine-adjustment tool allows the arm to turn knobs and align mirrors, while overhead cameras and a software stack enable autonomous assembly and real-time correction.

In a demonstration, the robot assembled and tuned a functional tabletop laser cavity in about 30 minutes through 50 autonomous steps. When the researchers introduced physical disturbances, the system automatically realigned the components to maintain stable laser intensity.

The team plans to present the system at the 2026 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in late September 2026. They also envision cloud-based access that would let scientists remotely run experiments on the physical robotic lab.
