A research team at Harvard University's Department of Bio-engineering and Applied Sciences has developed a bio-hybrid stingray robot. The biorobotic stingray is powered by rate muscle cells. According to the research team behind it, "the biorobotic stingray has pushed the field forward with a complex propulsion mechanism triggered by light, which allows the bio-bot to be steered around obstacles."
The remarkable bio-bot is made from rat muscle, elastic polymer (similar to breast implants) and gold. The skeletal structure of the stingray is made of gold, and the tiny biorobotic stingray is about the size of a penny. The scientists successfully got the bio-bot to mimic the swimming motion of a real stingray.
Kit Parker is the cardiac physiologist who created the idea for the biorobotic stingray. His hope is that this project will put biorobotics one step closer to being able to build a functioning human heart.
