The universe is big, and mapping it is a big project, so the 'Dark Energy Spectroscopic Instrument' will enlist the help of 5,000 robots. Commissioned by the US Depeartment of Energy, the mapping project is one of the most broad and technologically advanced efforts yet to understand the effects of dark matter on the expansion of the universe.
The Dark Energy Spectroscopic Instrument is essentially a system for focusing on each and every galaxy in the universe. In order to do so, the system uses 10 "petals" that contain a total of 5,000 fiber optic cables. These cables work like optics equipment, gathering light from different galaxies. To focus precisely and accurately, each cable is controlled by a 10 inch long, finger-width robot that works autonomously. The end result will be a 3D mapping of the entire universe.
