What is a robot?
According to wiki, a robot is a machine—especially one programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the control may be set within. Robots may be constructed to recall human form, but most robots are task-performing machines, designed with an attention on complete functionality, rather than expressive style.
What are the three main parts of robots?
1. The Controller ‐ also known as the “brain” which is run by a computer program. Usually, the program is very detailed and gives commands of what the programmer has programmed.
2. Mechanical parts ‐ motors, pistons, grippers, wheels, and gears that make the robot move, grab, turn, and lift. These parts are usually powered by air, water, or electricity.
3. Sensors ‐ to tell the robot about its surroundings. Sensors allow the robot to determine sizes, shapes, space between objects, direction, and other relations and properties of substances. Many robots can even identify the amount of pressure necessary to apply to grab an item without crushing it.
What do robots do?
Imagine if your job was to do the same thing over and over again without doing any mistakes or taking some break. This is what robots do they do those things in which they have to do one thing over and over again. Robots are really helpful and so they are helping in most of the factories, making chocolates, doing dangerous things which can lead to burning or something serious. Robotic technology has helped people who have lost arms or legs or even themselves. Robots are a great tool to help mankind.
What are nanobots?
Nanobots are robots scaled down to microscopic size in order to put them into very small spaces to perform a function. Currently nanobots are still in development stage. Future nanobots could be placed in the blood stream to perform surgical procedures that are too difficult for standard surgery. Nanobots could fight bacteria by eliminating each bacterial cell or could repair organ cells of the body.
Imagine if a nanobot could target cancer cells and destroy them without touching healthy cells nearby. Nanobots would carry medication and surgical tools on board. They could easily go inside the body and can easily find a way out. Nanobots could be used in many other situations too. Nanobots will be a great help for doctors as well.
So why use robots then?
The reason robots are used is that it is often cheaper to use them over humans, easier for robots to do some jobs and sometimes the only possible way to accomplish some tasks! Robots can explore inside volcanoes, travel the surface of Mars or other places too dangerous for humans to go where extreme temperatures or unclean environments exist.. Robots never get sick, don’t need sleep, don’t need food, don’t need to take a day off, does not ask for money in return, and best of all they don’t ever complain! There are a lot of benefits to using robots.
What are the things which robots can’t do?
Unlike in the movies, Robots are unable to think or make decisions; they are only tools to help us get things done. Robots are machines with programed movements that allow them to move in certain directions. Artificial intelligence has given robots more ability to process information and to “learn.” But, they are still limited by the information that they are given and the functions they are given to perform.
