Soft Robotics is a young field of robotics that keep growing everyday. However, many soft robotic projects in the community are simple actuators or soft sensors, not full soft robots. This is where the Crawli comes in. It's a crawling soft robot that only uses one air input. I've tried my best to make it as small and simple as possible. The Crawli consists of one seamless silicone cast that has two bending actuators for front legs and one large back leg. When the actuators inflate, they bend, pulling the Crawli forward. When the actuators are deflated, they unbend, but instead of moving the robot back to where it was, the back leg keeps it in place. This repeated sequence of motion always for the Crawli to walk.
