WHAT IS A ROBOT?

A robot is a machine—especially one programmable by a computer— capable of carrying out a complex series of actions automatically. Robots can be guided by an external control device or the control may be embedded within. Robots may be constructed on the lines of human form, but most robots are machines designed to perform a task with no regard to their aesthetics.

Robots that resemble humans are known as androids; however, many robots aren’t built on the human model. Industrial robots, for example, are often designed to perform repetitive tasks that aren’t facilitated by a human-like construction. A robot can be remotely controlled by a human operator, sometimes from a great distance. A telechir is a complex robot that is remotely controlled by a human operator for a telepresence system, which gives that individual the sense of being on location in a remote, dangerous or alien environment and the ability to interact with it. Telepresence robots, which simulate the experience and some of the capabilities of being physically present, can enable remote business consultations, healthcare, home monitoring and childcare, among many other possibilities.

An autonomous robot acts as a stand-alone system, complete with its own computer (called the controller). The most advanced example is the smart robot, which has a built-in artificial intelligence (Al) system that can learn from its environment and its experience and build on its capabilities based on that knowledge.

Swarm robots, sometimes referred to as insect robots, work in fleets ranging in number from a few to thousands, with all fleet members under the supervision of a single controller. The term arises from the similarity of the system to a colony of insects, where the individuals and behaviors are simple but the fleet as a whole can be sophisticated.

Robots are sometimes grouped according to the time frame in which they were first widely used. First-generation robots date from the 1970s and consist of stationary, nonprogrammable, electromechanical devices without sensors. Second-generation robots were developed in the 1980s and can contain sensors and programmable controllers. Third-generation robots were developed between approximately 1990 and the present. These machines can be stationary or mobile, autonomous or insect type, with sophisticated programming, speech recognition and/or synthesis, and other advanced features. Fourth-generation robots are in the research-and-development phase, and include features such as artificial intelligence, self-replication, self-assembly, and nanoscale size (physical dimensions on the order of nanometers, or units of 10- meter).

Some advanced robots are called androids because of their superficial resemblance to human beings. Androids are mobile, usually moving around on wheels or a track drive (robots legs are unstable and difficult to engineer). The android is not necessarily the end point of robot evolution. Some of the most esoteric and powerful robots do not look or behave anything like humans. The ultimate in robotic intelligence and sophistication might take on forms yet to be imagined.

HOW ARE ROBOTS USED FOR DANGEROUS JOBS?

There are many situations in which human beings can operate safely only by wearing bulky protective clothing and working for short periods at a time. Sometimes even that is not enough to protect them. If it is suspected that a booby-trapped bomb has been left in an abandoned vehicle, for example, a controlled explosion may be the only way of deactivating it. No matter how much protection a bomb disposal expert has, the explosion could be fatal if he or she is nearby. The answer is to use a robot carrying an explosive charge. The robot can be sent into the danger zone while experts remain at a safe distance. Although no one wants to destroy an expensive machine, the alternative is much worse.

Dirty jobs are often unsanitary or hazardous work that can impact human health. Even though these jobs are unfavorable, someone has to do them. They include waste management, livestock nurturing, and mine exploration. The robot can take away the risk from humans and keep them safe from harm.

One example is the need for sewer scrapers. When there is a problem with a sewer pipe, a crew shuts it off, digs to access the pipe, then fixes the infrastructure. But a robot can clean, map, and inspect pipes before the problems arise. Robots can also collect data like distance, pressure, temperature, and composition to get visibility of pollutants, infectious diseases, and drug use.

Dangerous jobs put humans in harmful situations. To prevent the loss of human life, robots can be used. They are able to measure and detect variables beyond human perception. Robots can defuse bombs, traverse distant planets, and inspect unstable structures. Robots are being used to inspect bridges. A high degree of expertise, risk, and cost is associated with manned bridge inspections. Multirotor drones are able to completely remove humans from dangerous situations. They inspect hard-to-access areas with advanced speed and maneuverability.
