Researchers have built a ‘soft robot’ that moves forward like a snake

The robot stores material at its centre and unravels forward thanks to air pressure in order to move.

Researchers at Stanford University have built a concept robot that moves forward by growing outwards, snaking forwards like an organism through cell development.

Using material that unravels from inside a singular tube and propelled forward using air pressure, the so-called “soft robot” is rigged up with a camera and sensors on the tip that can be used to guide and control its route.

The scientists behind the robot have published their work in a Science Robotics research paper as proof of concept ahead of future testing.

The Stanford team believe the robot could be used as part of search and rescue work in the future – working its way into and between small spaces currently not reachable safely by humans or by locomotive robots.

The use of air pressure and robust material for the outer tube also means the Stanford team have already been able to demonstrate the robot taking over load-bearing responsibilities in some instances.

The researchers say the robot could be used to deliver material through the centre of the tube, offering the example of using it to deliver water to disaster victims who may be trapped.
