The prototype tetrahedral walker robot resembles a tetrahedron. In the prototype, electric motors are located at the corners of the pyramid, which are called nodes. The nodes are connected to struts that form the sides of the pyramid. The struts telescope like the legs of a camera tripod, and the motors in the nodes are used to expand or retract the struts. This design allows the pyramid to move. Changing the length of its sides alters the pyramid’s center of gravity, which causes it to topple over. The nodes also pivot, giving the robot great flexibility. > Read More
