The MIT system uses a seven-jointed robotic arm with micron-scale precision to pick up lenses and mirrors placed in custom 3D-printed holders featuring QR codes. It executes precise manoeuvres to assemble setups, and if an experiment is disturbed, it detects the change and adjusts components to restore function.
The MIT team demonstrated the system by instructing the robot to construct a laser cavity, which uses mirrors and a crystal to amplify light. The robot successfully completed about 50 separate manoeuvres in roughly 30 minutes to assemble the setup and aligned the optical components to produce a working laser beam.
Researchers envision laboratories operating continuously where scientists can send experimental instructions remotely. The technology could support research into solar cells, sensors, cameras, displays, augmented and virtual reality systems, quantum technologies, and carbon-capture materials.
