Robots or Plants: What Grows Faster?

Author: Geared4Girls

Irvine, CA - June 18, 2026 - Living organisms constantly change. We eat food to grow, heal injuries, and replace damaged cells. The ability to regenerate has often been described as one of the key differences that separate living organisms and robots. 

Columbia’s engineering department recently developed a new concept called robot metabolism. Rather than relying on human engineering to manually repair them, these robots are designed to physically improve themselves. By collecting and reusing material from their surroundings, or even from other robots, they are able to withstand many challenges.

The adaptability of these robots stem from a module called the Truss Link. Each Truss Link is an expandable robotic bar equipped with magnetic connectors on both ends. These connectors allow multiple links to snap together at different angles, forming structures that range from simple frames to much larger and more complex robots. Because every module follows the same standardized design, robots can quickly rearrange, replace, or add pieces without requiring specially manufactured parts.

Traditional robots are designed for a specific task and maintain the same physical structure throughout their lifetime. If their environment changes or a component fails, they typically require human intervention to repair or redesign them.

Robots built from Truss Links operate differently. Because they can attach, detach, and exchange identical modules, they are capable of modifying their own bodies to meet new challenges.

The technology that robot metabolism introduces has the potential to transform how robots operate in unpredictable environments. Search-and-rescue robots responding to earthquakes or collapsed buildings could repair themselves or even reshape themselves to reach certain places without needing human repair.

Although robot metabolism is a technological breakthrough, the concept behind it extends far beyond robotics. Just as individual Truss Links become more capable when they connect to form a larger system, communities become stronger when people contribute their unique perspectives, experiences, and talents. At Geared4Girls, we have seen how mentorship, collaboration, and shared curiosity create opportunities that no one person could build alone.
