The University of Toronto in Canada has developed a pair of robotic grippers that can apply as little of 20 nanoNewtons of force on an object, using its three-millimeters-long arms to grab cells 10 micrometers across and transport them. What’s more, the gripper has sensors that allow it to know how hard it’s grabbing something and keep it from running into things – an important development for robotic grippers.
