Watch this cockroach robot squirm through a tricky obstacle course

A cockroach-inspired robot can handle complicated and bumpy terrain. It could be used for surveying earthquake rubble or even other planets. The robot, called Omni-Roach, has a rounded body, wings that can open and close, curved legs and a tail that can move left to right and up and down. It is around 20 centimetre long and 10 centimetres tall. Chen Li at Johns Hopkins University in Maryland and his team tested the robot in an obstacle course that mimicked the forest floor.
