Robotics Robotics - the development and study of machines that can perform work normally done by people Robot - an automatic device that performs functions ordinarily executed by human beings or that operates with what appears to be almost human intelligence
14 The Promises of the Digital Agee 14 Copyright © Exclusive rights by The McGraw-Hill Companies, Inc. Two Approaches to Artificial Intelligence: Weak versus Strong AI Weak AI - claims that computers can be programmed to simulate human cognition Strong AI - claims that computers can be made to think on a level that is at least equal to humans and possibly even be conscious of themselves Neural networks, genetic algorithms, and cyborgs are three examples of strong AI.
15 The Promises of the Digital Agee 15 Copyright © Exclusive rights by The McGraw-Hill Companies, Inc. Artificial Life, the Turing Test, & AI Ethics Artificial life or A-life - the field of study concerned with creatures that are created, replicate, evolve, and die as if they were living organisms
