Games and entertainmentStanford Cart Slider Modification by Hans Moravec
During the late 1970s, Hans Moravec at Stanford University extended the Stanford Cart, originally built by James L. Adams in the 1960s, with a sliding camera mount, enabling the robot to navigate autonomously across a chair-filled room in 1979 using stereo vision, a milestone in autonomous vehicle research.
Autonomous vehiclesHerbert A. Simon Awarded Nobel Memorial Prize in Economic Sciences for Bounded Rationality
In 1978, Herbert A. Simon of Carnegie Mellon University received the Nobel Memorial Prize in Economic Sciences for his theory of bounded rationality, which holds that human decision-making seeks satisfactory rather than optimal solutions owing to cognitive and informational constraints.
Regulation and policyBoris Chess Computer Released by Applied Concepts
In 1978, Applied Concepts released Boris, a dedicated chess-playing microcomputer programmed by David Lindsay and running on a Fairchild F8 processor with 256 bytes of RAM. It was among the earliest mass-market standalone chess computers available to home consumers.
Games and entertainmentMOLGEN: AI Planning and Constraint Satisfaction for Molecular Biology Experiment Design
In 1978, Mark Stefik at Stanford University's Heuristic Programming Project developed MOLGEN, an expert system that applied AI planning and constraint-satisfaction techniques to the design of molecular biology experiments, demonstrating that structured reasoning could automate complex scientific problem-solving in genetics and cloning.
BiologyMeta-Level Knowledge in Expert Systems: Davis and Lenat's Formalisation at Stanford
In 1977, Randall Davis and Douglas Lenat at Stanford University published research formalising meta-level knowledge, a system's explicit representations of its own knowledge and reasoning strategies, and demonstrated its application in the MYCIN and AM expert systems to improve inference control and self-directed learning.
Reasoning and planningAM: Automated Mathematician Developed by Douglas Lenat
In 1976, Douglas Lenat at Stanford University completed AM (Automated Mathematician), a heuristic program that explored elementary mathematics by modifying and combining LISP-coded concepts, discovering properties such as prime numbers without being explicitly programmed to do so.
Conjecture and discoveryABSTRIPS Developed by Earl Sacerdoti at SRI International
In 1974, Earl Sacerdoti at SRI International published ABSTRIPS, an extension of the STRIPS planning system that organised problem-solving into a hierarchy of abstraction spaces, allowing a planner to resolve high-level constraints before committing to fine-grained detail.
Theory and foundationsAaron: Harold Cohen's Generative Art Programme
From 1973, Harold Cohen at the University of California San Diego developed Aaron, a rule-based programme that autonomously generated original drawings by encoding explicit conditions for artistic decision-making, making it one of the earliest sustained AI systems for creative production.
Visual artFirst AI Winter: Lighthill Report and DARPA Funding Cuts
In 1973, James Lighthill's report for the British Science Research Council assessed artificial intelligence research and found it had failed to meet its goals; the report contributed to substantial funding cuts in the UK and, alongside DARPA reviews in the United States, precipitated the period known as the first AI winter.
Regulation and policyFREDDY II Robot, University of Edinburgh Department of Machine Intelligence and Perception
By 1973, researchers at the University of Edinburgh's Department of Machine Intelligence and Perception had developed FREDDY II, a robot arm system that used computer vision and tactile feedback to identify and assemble simple objects from a pile of scattered parts, demonstrating integrated perception and manipulation in a single robotic system.
Manipulation and dexterityHuman Associative Memory (HAM) Model Published by John R. Anderson and Gordon H. Bower
In 1973, John R. Anderson and Gordon H. Bower, both at Stanford University, published 'Human Associative Memory', introducing the HAM model, a propositional network architecture representing semantic memory as binary trees, providing a computationally explicit theory of human memory that influenced subsequent cognitive architectures.
Theory and foundationsLighthill Report on Artificial Intelligence
In 1973, Sir James Lighthill, Lucasian Professor of Applied Mathematics at the University of Cambridge, delivered a report to the UK Science Research Council concluding that AI research had failed to meet its stated goals, citing the 'combinatorial explosion' as the decisive technical barrier. The report prompted sharp cuts to UK government funding for AI.
Regulation and policyMIT Arm: Six-Axis Robotic Manipulator by Victor Scheinman
In 1973, Victor Scheinman at MIT completed the MIT Arm, a six-degree-of-freedom all-revolute robotic manipulator with DARPA funding. Its wrist-intersecting joint geometry simplified kinematic analysis and influenced the design of research and surgical robot arms for decades.
Manipulation and dexterityWABOT-1 Completed at Waseda University
In 1973, researchers at Waseda University in Japan completed WABOT-1, a full-scale anthropomorphic robot integrating limb control, machine vision, and Japanese-language conversation. It was among the earliest humanoid robots to combine locomotion, manipulation, and speech interaction in a single system.
Humanoid roboticsMYCIN: A Rule-Based Expert System for Infectious Disease Diagnosis, Developed at Stanford University
Beginning around 1972, Edward Shortliffe at Stanford University developed MYCIN, a rule-based expert system written in Lisp that used approximately 600 if-then rules to diagnose bacterial blood infections and recommend antibiotic treatments adjusted for patient body weight, establishing a widely studied model for clinical decision support.
DiagnosisProlog Logic Programming Language Created by Alain Colmerauer and Philippe Roussel
In 1972, Alain Colmerauer and Philippe Roussel at the University of Aix-Marseille created Prolog (Programmation en Logique), a declarative programming language grounded in first-order predicate logic, enabling computers to reason over symbolic knowledge without requiring procedural step-by-step instructions.
Theory and foundationsSmalltalk-72 Developed at Xerox PARC by Alan Kay, Dan Ingalls, and Adele Goldberg
In 1972, Alan Kay and Dan Ingalls at Xerox PARC produced Smalltalk-72, the first working implementation of the Smalltalk language, which embodied Kay's concept of object-oriented programming in which all computation proceeds by objects sending messages to one another.
Software engineeringStanford Cart Road-Following Experiment Under Les Earnest
In late 1971, Les Earnest at the Stanford Artificial Intelligence Laboratory adapted the Stanford Cart for autonomous road-following, using a television camera and a low-power radio control link to guide the vehicle along a road at approximately 0.8 mph (1.3 kph).
Autonomous vehiclesAugmented Transition Networks Introduced by William A. Woods
In 1970, William A. Woods of Bolt Beranek and Newman published 'Transition Network Grammars for Natural Language Analysis' in Communications of the ACM, introducing Augmented Transition Networks (ATNs) as a formalism for parsing natural language by extending finite-state transition networks with recursion and registers, enabling more expressive grammatical coverage.
