Robots & AI
Researchers designed the Rancho Arm at Rancho Los Amigos Hospital in Downey,
California as a tool for the handicapped. The Rancho Arm's six joints gave it
the flexibility of a human arm. Acquired by Stanford University in 1963, it
holds a place among the first artificial robotic arms to be controlled by a
computer.
