New Robotic Tweezers Can Grab A Single Human Cell

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.

Tiny Robotic Hand Has Strong Grip

Robotic Hand

Scientists have developed a pair of robotic hands that are both strong and sensitive

The tweezers can guide themselves to pick up and move individual cells without damaging them, and have a grip that can be as slight as 20 nanoNewtons of force. In fact, so advanced are the little grippers, that they can be hitched up to a microscope and, with the right software, function without human control. More below.
