robot (redirected from Robots)

robot or automaton (ôtäm`ətän') mechanical device designed to perform the work generally done by a human being. The Czech dramatist Karel Čapek popularized the expression [Czech,=compulsory labor] in his play R. U. R. (Rossum's Universal Robots), produced in Prague in 1921. Modern robotics has produced innumerable devices that replace human personnel, and the term robot is used to designate much of this machinery. It is used frequently in fiction, referring to a self-controlling machine shaped like a human being. While the concept has been the subject of stories since the golem of medieval times, it reached its greatest exposure in popular culture with the work of Isaac Asimov in the 1950s and the motion picture robots Robby in Forbidden Planet (1956) and C-3PO in Star Wars (1977).

robot

Any automatically operated machine that replaces human effort, though it may not look much like a human being or function in a humanlike manner. The term comes from the play R.U.R. by Karel Capek (1920). Major developments in microelectronics and computer technology since the 1960s have led to significant advances in robotics. Advanced, high-performance robots are used today in automobile manufacturing and aircraft assembly, and electronics firms use robotic devices together with other computerized instruments to sort or test finished products.

robot

A stand-alone hybrid computer system that performs physical and computational activities. Capable of performing many different tasks, it 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 entitled "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
Robots are designed for many purposes. In manufacturing, they 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 a myriad of 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.

Analog and Digital
Robots use analog sensors for recognizing real-world objects and digital computers for their direction. Analog to digital converters convert temperature, motion, pressure, sound and images into binary code for the robot's computer. The computer directs the physical actions of the arms and joints by pulsing their motors. See AIBO.

Shakey the Robot

Developed in 1969 by the Stanford Research Institute, Shakey was the first fully mobile robot with artificial intelligence. Shakey is seven feet tall and was named after its rather unstable movements. (Image courtesy of The Computer History Museum, www.computerhistory.org.)

Huey, Dewey and Louie

Named after Donald Duck's famous nephews, robots at this Wayne, Michigan plant apply sealant to prevent possible water leakage into the car. Huey (top) seals the drip rails while Dewey (right) seals the interior weld seams. Louie is outside of the view of this picture. (Image courtesy of Ford Motor Company.)

Inspect Pipes from the Inside

Developed by SRI for Osaka Gas in Japan, this Magnetically Attached General Purpose Inspection Engine (MAGPIE) goes inside gas pipes and looks for leaks. This unit served as the prototype for multicar models that perform temporary repairs while capturing pictures. (Image courtesy of SRI International.)

How Small Can They Get?

By 2020, scientists at Rutgers University believe that nano-sized robots will be injected into the bloodstream and administer a drug directly to an infected cell. This robot has a carbon nanotube body, a biomolecular motor that propels it and peptide limbs to orient itself. For more information, see http://bionano.rutgers.edu/Mavroidis_Final_Report.pdf.

1.	(robotics)	robot - A mechanical device for performing a task which might otherwise be done by a human, e.g. spraying paint on cars. See also cybernetics.
2.	(chat)	robot - An IRC or MUD user who is actually a program. On IRC, typically the robot provides some useful service. Examples are NickServ, which tries to prevent random users from adopting nicks already claimed by others, and MsgServ, which allows one to send asynchronous messages to be delivered when the recipient signs on. Also common are "annoybots", such as KissServ, which perform no useful function except to send cute messages to other people. Service robots are less common on MUDs; but some others, such as the "Julia" robot active in 1990--91, have been remarkably impressive Turing test experiments, able to pass as human for as long as ten or fifteen minutes of conversation.
3.	(World-Wide Web)	robot - spider.
