Delft Researchers Build Algae-Powered Robot Arm
3 min read
A team at Delft University of Technology developed a soft robotic arm colonized by algae that moves via photosynthesis. The device, about three-quarters of an inch long, bends when light triggers algae to change local pH, swelling the hydrogel in roughly 20 seconds. While it grasped light-sensitive items, significant bending takes several hours.
