Robot metabolism could help machines repair themselves without human intervention

Columbia University researchers have developed "Robot Metabolism," enabling robots to grow, heal, and improve autonomously. This innovation allows robots to absorb and reuse parts from their surroundings or other robots, mimicking biological adaptation. The team demonstrated this concept using "Truss Links," magnetic building blocks that self-assemble into complex structures. This technology could revolutionize disaster management and space exploration by creating self-sustaining machines that require minimal human maintenance.
