Shakey the Robot

What Happened

Shakey was the first mobile robot that could reason about its actions. It combined computer vision, natural language processing, and planning to navigate rooms, push objects, and solve simple tasks. It used the A* search algorithm and STRIPS planner.

Why It Mattered

Pioneered robotics planning and reasoning. The A* algorithm it used remains fundamental to pathfinding in games and navigation systems worldwide.

SHRDLU: Natural Language Understanding

Terry Winograd created SHRDLU, a program that could understand and respond to English commands about a simulated 'blocks world.' Users could ask it to move objects, answer questions about their arrangement, and even understand pronouns and context within its limited domain.

ELIZA: The First Chatbot

Joseph Weizenbaum created ELIZA, a program that simulated a Rogerian psychotherapist using simple pattern matching. Despite being purely rule-based with no understanding, users became emotionally attached to it and insisted it truly understood them — a phenomenon Weizenbaum found deeply disturbing.

DENDRAL: The First Expert System

DENDRAL automated chemical structure determination from mass spectrometry data. It used heuristic rules from domain experts to solve problems that normally required PhD-level expertise. Its successor Meta-DENDRAL could even generate new rules automatically.

The Dartmouth Conference

A two-month workshop at Dartmouth College where the term 'Artificial Intelligence' was officially coined. The proposal stated: 'Every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.' This gathering brought together the founders of the field.

The Perceptron

Frank Rosenblatt built the Mark I Perceptron, the first hardware implementation of an artificial neural network. It could learn to classify simple visual patterns. The New York Times reported it as an 'Electronic Brain' that the Navy expected would 'be able to walk, talk, see, write, reproduce itself and be conscious of its existence.'
