This beetle-robot walks with its four legs while swinging its horn. When it bumps into an obstacle, it turns around automatically and continues walking.
Motor rotation is transferred to the legs via crank plates and linkage rods, causing the Mechanical Beetle to walk forwards or backwards at one of two selectable speeds. A linkage rod connected to the beetle’s front right leg swings its horn left and right as the beetle walks. When it bumps into an obstacle, the beetle automatically turns to avoid it and continues walking. Because of this behavior, the beetle can provide amusement by simply running around in a small, enclosed space. The body is made from a transparent green ABS resin that allows you to see all of the motors, gears, cranks, and linkage rods in action.
