At the time, the robot Strut, a work in progress, could not walk at all, it could only stand. (It walked sometime later.) But simply getting the robot to stand properly was a major accomplishment. Like a human being, Strut has such complex, interreacting mechanical "musculature" that considerable processing power is needed simply to keep it erect.
