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.
Kirigami is a variation of origami that relies on cuts instead of folds.
The Harvard team thinks the 'snake' could be used during search and rescue missions, Newsweek reported.
Additionally, the researchers say it could be used in keyhole surgeries.
It is comprised of an elastic tube that repeatedly swells and then becomes smaller.
Plastic scales that are sliced onto the robot allow it to have a 3D, adaptable surface.
The scales replicate snakeskin, which allows snakes to move themselves forward.

Lasers slice small cuts in a plastic sheet that the engineers wrap around the robot's elastic tube.
As the tube expands the robot's scales move away from it and grip the surface
