Soft robots aren't as durable as their metallic counterparts, but they're getting better. Now, a team of engineers made a set that can self-repair.
The bots are made of temperature-sensitive rubber. When heated, its polymers break down and move to areas that need sealing. As it cools, those polymers form a bond, closing the gap.
The material seems to be efficient. The scientists said the robots repaired themselves almost perfectly during tests.
The team said although these robots don't have a specific application, the eco-friendly manufacturing method could be a model for making other soft bots.
