Robot Eat Robots Metabolism Grow
Columbia University’s latest engineering project is straight out of a sci-fi novel, but it’s based on a simple idea: what if robots could grow, heal and adapt by absorbing parts from other robots?

The X-59 rolled out of the Lockheed Martin Skunk Works hangar in Palmdale, California on July 10, 2025 and is now taxiing on its own power for the first time.

Central to the Quesst mission is the X-59 which will change the way we think about supersonic travel and potentially open the skies to commercial aviation.
