The Age of Robotics

“If every tool, when ordered, or even of its own accord, could do the work that befits it... If the weavers' shuttles were to weave of themselves, then there would be no need either of apprentices for the master workers or of slaves for the lords.”

Aristotle, “De Republica Atheniensium”, ~322 BC

Sounds and Prior Information

What about the rest?

2 May 2008 Kevin H Knuth NTIR 2008

Prior Information is Key

Only 10% of the inputs into primary visual cortex come from the retina via the lateral geniculate nucleus. The rest come from higher visual and frontal areas.

Perception can also be modified by attention.

Thus the brain can actively focus on relevant information.

The Brain Models its Environment

The frontal regions of the braincreate models of the world basedon prior experience. Thesemodels affect perception and attention.

In addition, the brain modelsitself.

Experiments in multi-sensoryprocessing has shown thatthe information processing is consistent with Bayes Theorem

Thinking Machines

Your frontal lobes carry a model of yourself that is continually updated from data received from a dense sensor network. This implements both ‘Instrument Health Monitoring’ and ‘Calibration’

You learn from new data by updating your model of the world.

You actively seek new data by asking relevant questions.

Underwater Robotic Explorers

At the Monterey Bay Aquarium Research Institute (MBARI), researchers are employing robotic submarines to explore the Deep Pacific Ocean.

Intelligent Autonomous Instruments

Require:

Stability Control

Instrument Health Monitoring

Automated Calibration

Accurate Onboard Data Analysis

Adequate Data Coverage

Ability to Actively Seek Data

2 May 2008 Kevin H Knuth NTIR 2008

Novel Instrument Design

To accomplish these goals, these novel instruments must

Monitor their own state (health and calibration) Infer their state from self-sensing Be equipped with dense sensor networks Infer calibration parameters

Learn from data Make inferences from data Perform hypothesis testing

Ask new questions Actively seek new data Select optimal experiments

'Am I already in the shadow of the Coming Race? and will the creatures who are to transcend and finally supersede us be steely organisms, giving out the effluvia of the laboratory, and performing with infallible exactness more than everything that we have performed with a slovenly approximativeness and self-defeating inaccuracy?'

The Impressions of Theophrastus Such, 1879.
