Harvard researchers developed a 'robot snake'

Researchers have created a robot that can slither like a snake - and it might be used in laparoscopic surgeries. The invention is the latest in a slew of new robotic developments. Engineers have recently come up with robots that can glide across water, open doors and lift up to 1,000 times their weight. Now, scientists from Harvard have created one that can slither using artificial scales, according to new research published in Science Robotics. Researchers designed the'robot snake' by using a type of paper cutting art, called kirigami, to engineer the device.
