About

Guillermo Glez-de-Rivera is a pioneering roboticist whose work bridges precision engineering and large-scale astrophysics. His primary research areas include robotic instrumentation for astronomy, multirobot control systems, and energy-efficient manipulator design. Glez-de-Rivera’s most transformative contribution is his leadership in developing the robotic focal plane system for the Dark Energy Spectroscopic Instrument (DESI), a project that deployed 5,020 autonomous fiber positioners on the Mayall Telescope. These micro-robots, each the size of a pen, automatically retarget optical fibers every 10–20 minutes with micron-level precision—a feat that enables massive spectroscopic surveys probing dark energy and the Milky Way’s formation. This work, detailed in his 2022 paper (175 citations), represents a landmark in astronomical instrumentation. He has also advanced cooperative robotics, proposing novel control strategies for heterogeneous robot groups that optimize secondary objectives like energy consumption. Earlier contributions include low-cost ultrasonic positioning systems and educational robotic arms. With over 250 total citations, Glez-de-Rivera’s career exemplifies how precision robotics can unlock new frontiers in cosmology, making him a key figure at the intersection of engineering and fundamental science.
