From The Verge via Science Robotics:
The arm, described in a study published today in Science Robotics, is made of seven plastic actuators that look like rectangular boxes stacked up on top of each other and stretching up to 27.5 inches (70 centimeters) in length. But what’s special about the actuators is that they can be folded flat, so that the arm is stowed away. Scientists attached the arm to a drone. When equipped with finger-like grippers, the arm could grab an object at the bottom of a ditch. When equipped with a camera, it could take video among tree branches.
“Folding, packaging of everyday things are everywhere,” study co-author Kyu Jin Cho, director of the Soft Robotics Research Center at Seoul National University, tells The Verge in an email. “Why not for robots?”
