Handling fragile objects like fruits, glass, or biological tissues has always been a challenge for robots. Traditional robotic arms rely on force and precision, which often damages delicate items. To solve this, researchers at Harvard’s John A. Paulson School of Engineering and Applied Sciences have taken inspiration from jellyfish. They designed a soft robotic gripper that mimics jellyfish tentacles, wrapping gently around objects without breaking them.

The gripper works on a simple principle: hollow rubber tubes curl when air is pumped inside. When several of these “tentacles” inflate together, they entangle and hold an object softly yet securely — a process called topological grasping. Unlike complex robotic hands, this system doesn’t need sensors, AI, or heavy programming. Its power lies in simplicity and softness.

This breakthrough could transform multiple industries. In agriculture, it could harvest delicate fruits like strawberries without bruising them. In medicine, it could handle sensitive tissues during surgeries. In manufacturing, it could safely move glassware or electronics. Even in homes, such grippers could help personal robots handle daily tasks without accidents.

By embracing flexibility instead of force, this invention shows that in robotics, sometimes gentle is powerful. It’s a step toward safer, smarter, and more adaptable machines.
