In a break from tradition, Kawasaki, a Japanese motorcycle maker, has announced plans to build a new breed of off-road machine shaped like a robotic horse. Corleo, as the machine is called, has a body like a headless steed, complete with four multi-jointed legs powered by electric motors. A pair of handlebars serves as reins and adjustable leg supports, of the kind found on motorbikes, pass for stirrups. Corleo will also not require a farrier: instead of being shod with steel horseshoes, its hooves are clad in rubber. This will help it absorb shocks and improve its grip.
