         MIT Scientists: Robots Will Soon be Able to Run Like Cheetahs

   Scientists have been experimenting with four-legged robots for years,
   trying to see if they could be used as pack animals for carrying heavy
   loads over a difficult terrain. But the machine's power requirements
   limited their potential. That's changed, with a running robot designed
   by a group of engineers at Massachusetts Institute of Technology that
   operates on batteries rather than heavy gasoline-powered engines. VOA's
   George Putic reports.
