Researchers develop first-ever wooden robotic gripper that is driven by moisture, temperature and lighting

Most robotic grippers are made using either soft plastics—to pick up objects without damaging them—that melt at high temperatures, or metals which are stiff and costly. A team of researchers from the National University of Singapore (NUS), together with their collaborators from the Northeast Forest University, have created a wooden robotic gripper that could be used in a very hot environment and yet maintain a tender touch.
