INSTITUTO FUTURISTA

Climbing the walls: As the robot’s motor turns, its tail presses against the surface, and its triangular legs rotate forward (a). As its front feet come into contact with the surface, the motor torque caused by the tail’s contact with the surface presses the front feet against the surface while pulling away the rear feet (b). When the force acting on the rear foot reaches a critical point, it peels away from the surface, and the robot steps forward (c).
