People need robots for dangerous, repetitive and high-precision work. Robots perform tasks in hostile environments that are impossible for humans, while also carrying out repetitious tasks with speed and accuracy. Without robots, our modern industrialized world would not be possible.Continue Reading
The world needs robots for a countless number of reasons, including hazardous jobs and automated manufacturing. Robots work without breaks or the need to sleep or eat, allowing manufactures to streamline processes and improve output. Robots are employed in roles ranging from cleaning up dangerous waste and chemical spills to disarming bombs and protecting soldiers in the field. New, humanoid robots and "exo-suits," originally designed for military use, are now being developed in the private sector for uses ranging from manual labor to helping those with handicaps and mobility issues.
Robots also provide a level of precision that is unmatched by the human hand, and one which is repeatable over indefinite time frames. These characteristics make them ideal for precision cutting, welding and assembly processes. Robots are also revolutionizing medical procedures, allowing many types of surgery to be performed with non-invasive, out-patient procedures, as opposed to traditional procedures requiring longer recovery times. Medical robots are now so advanced that they are being employed in brain, heart and eye surgeries, allowing doctors to treat conditions that were previously only possible through treatments nearly as dangerous as the offending condition.Learn more about Inventions
The combination of a wheel and axle is a simple machine that consists of a large wheel attached to a smaller wheel called an axle that turns on the same axis. When the large wheel is turned, the axle also turns.Full Answer >
Telegraph keys are switches in electrical circuits that power on the current. When the operator taps out the signals for a word, the switch finishes a circuit, permitting electricity to continue around it. At the other end of the line, the recipient watches a pointer or dial indicating the different patterns of code, listens to a buzzer or reads the print out from a device.Full Answer >
Machines make work easier by changing the force on an object. Work occurs when an individual applies force to an object, and when a machine is used, the machine applies the force to the object instead of the individual.Full Answer >
A telegram is a message sent through electrical signals fed through a wire. Most telegrams use Morse code to transmit and receive signals through the wire.Full Answer >
