5000 Robots Merge to Map the Universe in 3D
20 March 2019
How do you create the largest 3D map of the Universe? You need to study 10s of millions of galaxies! To accomplish that Herculean task, the Dark Energy Spectroscopic Instrument (DESI), which is being installed on the Kitt Peak Mayall telescope, will use an array of robot fiber-positioners that will automatically swivel into position to capture the spectra of 5000 galaxies at a time. This video describes how scientists working at Berkeley Lab are assembling the array of robots and their related electronics.
