For some years the United States Atomic Energy Commission has used mechanical extensions to men's arms as a way of handling dangerous radioactive materials. Now NASA -- the space agency -- is testing these devices which exactly duplicate the movements of mens hands to see if they can be used in the American space programme.
At a Nevada testing station the Agency is using arms that can reproduce the movements of hands extraordinarily accurately.
The hands can handle scientific instruments and in one experiment be controlled by radio on the back of a truck. One day, perhaps, an astronaut on a lunar lander might explore the moon without ever leaving the cabin of his craft. The space agency predicts that eventually the robot arms could prove useful in repairing or inspecting satellites and space stations. In this way potentially hazardous tasks could be performed without putting humans at risk.
One futuristic device is a walking machine. Two of the legs of this vehicle of the future are controlled by the man's leg movements. His two hands guide the other two limbs of the machine.
