MIT Robot Builds a Working Laser in 30 Minutes With Minimal Human Help

MIT researchers have developed a self-aligning robotic optics lab capable of assembling, aligning, monitoring and dismantling precision experiments with minimal human intervention. The system, designed to tackle one of the slowest parts of optics research, can build a tabletop laser cavity from randomly positioned components in about 30 minutes, completing 50 maneuvers.

The robot uses a seven-joint robotic arm, magnetic bases, and Wi-Fi-enabled adjustment tools to position and fine-tune components with micron-scale precision. Two overhead cameras provide a view of the workspace while software handles component recognition and movement planning. MIT physics professor Marin Soljacic believes the technology could enable scientists to push theories and theories faster by freeing up time and creativity for more advanced work.

The system could eventually be used for prototype testing in various technologies such as cameras, displays, solar cells and AR/VR goggles. MIT is also developing cloud-based access to allow remote submission of experimental protocols to robotic labs. While the current system remains a tabletop research prototype, researchers aim to improve its sensing, maneuverability and usable workspace, and plans for remote access are in the works.
