Robotic Ray with Rodent Cells

Yes, researchers have created one of the things we have all been waiting for: A robotic ray. It represents the latest in tissue-engineering. By Kate Stone 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. 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 flat bodies and long, wide, winglike fins. These fins…
