A CDE Definition
A stand-alone hybrid computer system that performs physical and computational activities. Capable of performing many tasks, a robot is a multiple-motion device with one or more arms and joints. Robots can be similar in form to a human, but industrial robots do not resemble people at all.
The term is attributed to Czech dramatist Karel Capek in his 1921 play titled "R.U.R. - Rossum's Universal Robots." Capek applied the Czech word "robota," which means "forced labor" or "servitude" to the mechanized people in the skit. Three years later, robots appeared in Fritz Lang's classic silent movie "Metropolis," and they have been with us ever since.
A Wide Variety of Applications
In manufacturing, robots are used for welding, riveting, scraping and painting. They are also deployed for demolition, fire and bomb fighting, nuclear site inspection, industrial cleaning, laboratory use, medical surgery (see telepresence surgery), agriculture, forestry, office mail delivery as well as many other tasks. Increasingly, more artificial intelligence is being added. For example, some robots can identify objects in a pile, select the objects in the appropriate sequence and assemble them into a unit (see AI).
Analog and Digital
Robots use analog sensors for recognizing real-world objects and digital computers for direction. Analog to digital converters convert temperature, motion, pressure, sound and images into binary code for the robot's computer, which directs the actions of the arms and joints by pulsing their motors. See AIBO.
