Robot snake can move at 20mph in rescue missions

A snake-like robot that can coil and unravel itself at speeds of 20mph (32 km/h) could be used to save lives during search and rescue missions. The 72-metre-long (236ft) robot can sneak around corners and even turn handles and taps using its bendy body. Researchers hope that the robot could one day slither into cramped spaces to aid rescue workers, or perform odd jobs inside structures such as radio antennae. Researchers created the robot using inspiration from the plant kingdom. Unlike animals, plants move from one place to another by growing in a particular direction.
