Even the best telescopes have blind spots. This fix can help us build better maps of the universe

Sometimes, mapping the whole universe starts with getting thousands of tiny robots to move in exactly the right way.

• DESI telescope uses robots to position optical fibers for light collection
• Robots face physical constraints like collisions and crowded galaxy areas
• Computer tool models robot behavior to optimize telescope data collection
