Using snakelike skin, this robot from Harvard researcher Ahmad Rafsanjani, has the ability to crawl. Using a technique similar to origami called kirigami, the skin is created using cutting as well as folding.
The cut out skin is wrapped around a rubber cylinder which can be inflated or deflated. A trapezoidal cutout on the skin is so far the most effect for moving the robot forward. Looks can be deceiving. It took Rafsanjani a year and a half to perfect the skin and robot before it worked correctly.
