An interesting simple way to activate soft robots, which could have numerous applications tight environment. The video is worth a look.

>>Though inspired by the snake, a new soft robot out of Harvard takes cues from another source: the Japanese paper craft kirigami. Unlike origami, kirigami uses cuts rather than folds. Here, the Harvard team have applied the artform to create a soft robot that grips the ground much like a snake.<<​

Looks more like a caterpillar than a snake.

The part of this that delights me is that the robot has only two moving parts. A rubber inner part that expands due to air pressure and a flexible skin. That’s fewer moving parts than any other moving object other than a ball or slinky.

Further, the number of moving parts could even be reduced to one.

I think the speed of motion could be improved a lot. Eg. By using a bigger air hose or better control of curvature.

My sister has a wooden snake toy with joins that allow it to slither side to side in a very lifelike manner when its tail is twisted slightly. I wonder if that could be turned into a robot. Yes it can. Here is a snake robot.
