Summary

Australian-American AI researcher and robotics pioneer who argued that intelligence is not about central symbolic representation but about embodied, reactive behaviors — the subsumption architecture.

Core Contribution

Intelligence Without Representation (1991): sophisticated behavior can emerge from simple reactive systems without any central world model — the world is its own best representation. Subsumption architecture: layers of reactive behaviors without a central planner. Founded iRobot (Roomba) and Rethink Robotics.

Key Spikes & Highlights

  • Intelligence Without Representation was a direct attack on GOFAI (Good Old-Fashioned AI): instead of modeling the world, represent nothing — just sense and react. This prefigured embodied cognition and modern deep RL agents.
  • The Roomba is the most successful robot ever sold — a direct implementation of subsumption architecture, with no internal world model.
