Robotic Ray with Rodent Cells

By Kate Stone Yes, researchers have finally created one of the things we have all been waiting for: A swimming robotic ray. Not an RC Car This isn’t a rubber stingray that works like a radio-controlled car or a programmable rover. This robotic stingray is powered and guided by light-sensitive rat-heart cells. Yes, you read that correctly. [tweetthis]Robotic stingray swims with rat cells and electrical signals.[/tweetthis] The project demonstrated a new method for building bio-inspired robots by means of tissue engineering. Batoid fish, such as stingrays, are recognizable by their…

Micro-robots for Search and Rescue Missions

Imagine an army of tiny robots no bigger than a penny scrambling through the rubble of a disaster site to search for victims and to assess the damage. That is the vision of engineer Sarah Bergbreiter and her research team at the University of Maryland, who are building micro-robots with support from the National Science Foundation (NSF). The researchers are currently testing a variety of different materials and designs on bigger robots before scaling them down to the final size. But even the larger prototypes of these robots are so…
