12 AI Milestones: 1. Shakey The Robot Posted on : Jan 20 - 2020

Developed at the Artificial Intelligence Center of the Stanford Research Institute (SRI) from 1966 to 1972, SHAKEY was the world’s first mobile intelligent robot. According to the 2017 IEEE Milestone citation, it “could perceive its surroundings, infer implicit facts from explicit ones, create plans, recover from errors in plan execution, and communicate using ordinary English. SHAKEY's software architecture, computer vision, and methods for navigation and planning proved seminal in robotics and in the design of web servers, automobiles, factories, video games, and Mars rovers.”

In November 1963, Charles Rosen, head of the AI group at SRI, wrote a memo in which “he proposed development of a mobile ‘automaton’ that would combine the pattern-recognition and memory capabilities of neural networks with higher-level AI programs,” according to Nils Nilsson in his book The Quest for Artificial Intelligence. In April 1964, SRI submitted to the Advanced Research Projects Agency (ARPA) at the U.S. Department of Defense, a proposal for research in “Intelligent Automata,” which it claimed would ultimately lead to “the development of machines that will perform tasks that are presently considered to require human intelligence.” ARPA awarded SRI “a rather large (for the time) contract” (says Nilsson) with the start date of March 17, 1966.

Later, Rosen recalled the origin of the robot’s name: “We worked for a month trying to find a good name for it, ranging from Greek names to whatnot, and then one of us said, ‘Hey, it shakes like hell and moves around, let’s just call it Shakey.’” Nilsson: “Because of various engineering idiosyncrasies, the vehicle shook when it came to an abrupt stop.”

According to the IEEE, Shakey was envisioned as “an experimental platform for integrating all the subfields of artificial intelligence as then understood. Logical reasoning, autonomous plan creation, robust real-world plan execution, machine learning, computer vision, navigation, and communication in ordinary English were integrated in a physical system for the first time…

In more specific technical terms, Shakey is historically significant for three distinct reasons: (1) Its control software was structured—a first for robots—in a layered architecture that became a model for subsequent robots; (2) Its computer vision, planning and navigation methods have been used not only in many subsequent robots, but in a wide variety of consumer and industrial applications; and (3) Shakey served as an existence proof that encouraged later developers to develop more advanced robots.” View More
