Study Notes

Architectures for Autonomy

  • Autonomy has a distinct programming style
  • It involves considerations of how much AI a robot needs
  • Intelligence can be added in layers (like upgrading or downloading)

Specific Learning Objectives

  • Apply Levis' definition of architectures to organize software in an intelligent robot and understand how it guides design
  • Name and describe the layers (behavioral, deliberative, interface) within a canonical operational intelligent robot in terms of the five attributes
  • Name the four primitives of robotic intelligence: sense, plan, act, learn
  • List vulnerabilities (e.g. where poor choices lead to failures) in the canonical operational architecture

Given That Autonomy Has a Different Programming Style, What Is It?

  • Architectures, specifically operational architecture
  • Biological operational architecture
  • Recast as a process
  • Recast as a function
  • Ramifications

Organizing Software

  • Overall style of design is called "architecture"
  • Provides a principled way of organizing a control system
  • Imposes constraints on how the control problem can be solved

The Three Types of Software Architecture

  • The term "architecture" is frequently used in robotics to refer to the overall style of design or organization.
  • Architecture describes a set of architectural components and how they interact
  • Provides a principled way of organizing a control system (providing structure)
  • It imposes constraints on the way the control problem can be solved

Types of Architectures [Levis, George Mason University]

  • Operational architecture: describes what the systems does at a high level, not how it does it
  • Systems architecture: describes how a system works in terms of major subsystems
  • Technical architecture: describes how a system works in terms of implementation details, language

Focus of this Course

  • operational architecture: describes what the systems does, not how it does it
  • systems architecture: describes how a system works in terms of major subsystems
  • technical architecture: implementation details, language

Why Worry About Software Organization?

  • Recall at least 7 distinct areas of Artificial Intelligence, each with its own algorithms and data structures; these have to be "knitted" together somehow
  • Artificial intelligence is a software enterprise, and good software engineering is necessary for a successful software enterprise

Thinking About Architectures is Good Software Engineering

  • Thinking of the design of an autonomous robot in terms of the three architectures encourages the creation of designs that meet the four general principles of software engineering
  • Abstraction
  • Modularity
  • Anticipation of change, with incrementality
  • Generality

Architectures is Good Software Engineering

  • In addition to the four general principles of software engineering, Arkin adds two more (niche targetability and robustness) for AI robotics
  • Niche targetability captures how well the robot works for the intended application
  • Robustness identifies where the system is vulnerable, and how the system design intrinsically reduces that vulnerability
