Robotics Essay, Research Paper Robotics Robot is a computer-controlled machine that is programmed to move, manipulate objects, and accomplish work while interacting with its environment. Robots are able to perform repetitive tasks more quickly, cheaply, and accurately than humans. The term robot originates from the Czech word robota, meaning “compulsory labor.” It was first used in the 1921 play R.U.R. (Rossum’s Universal Robots) by the Czech novelist and playwright Karel Capek.

Robot is a computer-controlled machine that is programmed to move, manipulate objects, and accomplish work while interacting with its environment. Robots are able to perform repetitive tasks more quickly, cheaply, and accurately than humans. The term robot originates from the Czech word robota, meaning “compulsory labor.” It was first used in the 1921 play R.U.R. (Rossum’s Universal Robots) by the Czech novelist and playwright Karel Capek. The word robot has been used since to refer to a machine that performs work to assist people or work that humans find difficult or undesirable.
The first true feedback controller was the Watt governor, invented in 1788 by the Scottish engineer James Watt. This device featured two metal balls connected to the drive shaft of a steam engine and also coupled to a valve that regulated the flow of steam. As the engine speed increased, the balls swung out due to centrifugal force, closing the valve. The flow of steam to the engine was decreased, thus regulating the speed. the modern robot. A primitive arm that could be programmed to perform specific tasks was developed by the merican inventor George Devol, Jr., in 1954. In 1975 the American mechanical engineer Victor Scheinman, while a graduate student at Stanford University in California, developed a truly flexible multipurpose manipulator known as the Programmable Universal Manipulation Arm (PUMA). PUMA was capable of moving an object and placing it with any orientation in a desired location within its reach. The basic multi-jointed concept of the PUMA is the template for most contemporary robots.
In 1995 about 700,000 robots were operating in the industrialized world. Over 500,000 were used in Japan, about 120,000 in Western Europe, and about 60,000 in the United States. Many robot applications are for tasks that are either dangerous or unpleasant for human beings. In medical laboratories, robots handle potentially hazardous materials, such as blood or urine samples. In other cases, robots are used in repetitive, monotonous tasks in which human performance might degrade over time. Robots can perform these repetitive, high-precision operations 24 hours a day without fatigue. A major user of robots is the automobile industry. General Motors Corporation uses approximately 16,000 robots for tasks such as spot welding, painting, machine loading, parts transfer, and assembly. Assembly is one of the fastest growing industrial applications of robotics. It requires higher precision than welding or painting and depends on low-cost sensor systems and powerful inexpensive computers.
Robots are used in electronic assembly where they mount microchips on circuit boards. Robots are being used to assist surgeons in installing artificial hips, and very high-precision robots can assist surgeons with delicate operations on the human eye. Research in telesurgery uses robots, under the remote control of expert surgeons that may one-day perform operations in distant battlefields.
The use of robots has made our economy much more efficient and precise. Robots all industries to produce much more items with a lot more precision. This also is cheaper for the manufacturer in the long run as it goes for costs for a robot vs. human.
Some limitations of robots are their maintenance, when a robot brake down it will cost the manufacturing plant thousands of dollars. Humans also are more thought full and are safer then robots in some situations but not all. Robots also create manufactured products that are of higher quality and lower cost. But robots can cause the loss of unskilled jobs, particularly on assembly lines in factories.
Automated machines will increasingly assist humans in the manufacture of new products, the maintenance of the world’s infrastructure, and the care of homes and businesses. Robots will be able to make new highways, construct steel frameworks of buildings, clean underground pipelines, and mow lawns. Prototypes of systems to perform all of these tasks already exist.
One important trend is the development of micro-electromechanical systems, ranging in size from centimeters to millimeters. These tiny robots may be used to move through blood vessels to deliver medicine or clean arterial blockages. They also may work inside large machines to diagnose impending mechanical problems.
Perhaps the most dramatic changes in future robots will arise from their increasing ability to reason. The field of artificial intelligence is moving rapidly from university laboratories to practical application in industry, and machines are being developed that can perform cognitive tasks, such as strategic planning and learning from experience. Increasingly, diagnosis of failures in aircraft or satellites, the management of a battlefield, or the control of a large factory will be performed by intelligent computers.
