This gecko-inspired robot amputates its own limbs to survive

In Connecticut, researchers have developed a palm-sized silicone robot capable of self-amputation, similar to a gecko shedding its tail. In a demonstration, a brick fell on the robot's leg, and it detached to escape, leaving the limb behind. The robot's innovation lies in its joints, which are bonded by a substance that transitions from solid to liquid-like when heated, enabling limb detachment and reattachment.

This soft robot, designed by Yale University researchers, can reconfigure itself and join with other modules to tackle tasks that would be impossible for a single unit. The adaptability of such robots, made from pliable materials, contrasts traditional robots made of metals and plastics, offering potential in environments requiring flexibility. Such innovations could be beneficial in search and rescue missions or planetary exploration.

Research efforts continue to expand these capabilities, with ongoing projects exploring robotic turtles transitioning between land and water. The advancement highlights the fusion of nature-inspired solutions with modern robotics to meet diverse challenges.
