Making Decisions and Avoiding Obstacles

Autonomous Motion

A robot takes action on its own – without a human operating it with a control device

Obstacle Detection

Wall Detection

Following a Path

Contact with Humans

Physical Barriers and Interlocks

Double Reset or Interlock

Human Avoidance with Patterns

Coordinated Action

Coordination with Conveyors

Coordination with machines

Environmental Sensing

3D IR with Laser Sensing

Behavior Based Robotics

Subsumption Architecture

Many "simple" behavior modules

Each implements one goal

BEAM Robotics

an acronym for Biology, Electronics, Aesthetics, and Mechanics.

Produces complex robotic movements from simple analog logic circuits, often with discrete electronic components, and usually without a microprocessor.

Artificial Intelligence

How AI Robots are Learning

Robot Operations without AI

Summary

Autonomous motion can be accomplished using very basic sensors and logic or with advanced artificial intelligence.

Uses – obstacle avoidance, following, avoiding humans, coordinated motion.

Sensors with programming are the primary method used for autonomous motion.

Other methods include pattern recognition, behavior based robots, and artificial intelligence.
