1.Scientists have been experimenting with four-legged robots for years,trying to see if they could be used as animals for carrying heavy loads over a difficult place.But the machine’s power requirements limited their ability.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.
