Robots That Eat Robots: Columbia's Cannibalistic Breakthrough

We have entered the era where robots eat other robots to fix itself. Columbia University calls it "metabolism." I call it the beginning of machine evolution.

Philippe Martin Wyder's team at Columbia Engineering just shattered the boundary between biology and robotics. Their Truss Links, expandable robotic bars with magnetic connectors, don't just connect. They consume. Starting with six independent units, researchers watched them self-assemble into triangles, stars, then three-dimensional tetrahedrons. When damaged, they heal by cannibalizing faulty parts.

The breakthrough isn't the hardware, it's the philosophy. "Robot minds have moved forward by leaps and bounds," says Professor Hod Lipson, "but robot bodies are still monolithic, unadaptive, unrecyclable." Biology thrives on modular adaptation. Now robots can too. These machines integrate material from other robots into their bodies, growing stronger, adapting faster.

The implications cascade beyond labs. Driverless cars repairing themselves from salvaged parts. Manufacturing robots evolving their configurations mid-production. Space exploration machines sustaining themselves indefinitely. We're witnessing the birth of open-system robotics—machines that absorb resources like living organisms.

This isn't science fiction. It's published today in Science Advances. When robots metabolize, adapt, and self-sustain, the line between synthetic and organic intelligence doesn't just blur, it disappears.

• Robots now grow by consuming other robots' parts
• Self-healing machines require zero human maintenance
• Modular robotics mimics biological metabolism perfectly

When machines learn to eat, evolve, and heal themselves, are we still their creators or just their ancestors?
