Gat's ATLANTIS Architecture

Reference

Architecture Background

Architecture

• Three layers of control
  • Control layer
  • Sequencing layer
  • Deliberative layer

Agent Properties

• Control layer
  • Highly reactive
  • Low level of abstraction
  • Little computation
  • Short-term effects
  • Ephemeral State
• Sequencing layer
  • Cognizant failure
  • Moderate level of abstraction
• Deliberative layer
  • High level of abstraction
  • Requires more computational resources
  • Long-term effects
  • Symbolic world model
• Emergent
  • Hierarchy of levels
  • Varying amounts of computation
  • Varying amounts of state information
  • Limited sensing
  • Flexibility
  • "Black Box" Architecture

Capabilities

• Focused actions
• Planning and prediction
• Taskable
• Goal-directed behaviour
• Intelligent reactions to interrupts (Wesson Oil Problem)
• Recovery from failure
• Knowledge at different levels of abstraction
• Replanning

Environment

• Regularities at different time scales
• Dynamic
• Real World
