These Robotic Arms Are Powered by Algae. Watch How They Move

These Robotic Arms Are Powered by Algae. The key to the movement of these flexible robots is the algae's photosynthetic capabilities. Researchers can control the movement of these soft robotic arms just with light. What if a robot could be squishy? Soft, flexible robots could be useful for a wide variety of applications, including artificial muscles and wearable devices --or really any application where a robot must be especially delicate .
