An Ancient Stingray Lookalike Inspires Underwater Soft Robotics


Fossil animals are informing the field of soft robotics, and applications are abundant.

Published in PNAS in November 2023 and set to appear in a presentation at the 68th Biophysical Society Annual Meeting in February 2024, the researchers’ work testifies to the wide variety of applications of ancient-animal-inspired robotics. In fact, in recent years, researchers turned to flexible bots more often as a tool for revealing the biomechanics of animals, including snakes, salamanders, sea turtles, and many more. Not only that — it is possible that the tactic, which the team calls “paleobionics,” could contribute to the study of the ocean or assist in completing complex tasks underwater, by building on long-lost forms of ancient movement.
