The ASIMO robot

A robot is an artificial agent, meaning it acts as a substitute for a person, doing things it is designed for.

Robots are usually machines controlled by a computer program or electronic circuitry. They may be directly controlled by humans. They may be designed to look like humans, in which case their behaviour may suggest intelligence or thought. Most do a specific job, and they do not look like humans. They can come in many forms.

In fiction, however, robots usually look like people, and seem to have a life of their own. There are many books, movies, and video games with robots in them. 's I, Robot is perhaps the most famous. Contents

Model of Leonardo's robot with inner workings. Possibly constructed by Leonardo da Vinci around the year 1495.

W. H. Richards with "", 1932

People have been interested in building machines to do work for us for a long time. But it takes time and money to build just one machine, so early ideas stayed ideas, or were built to make rich people laugh. Leonardo da Vinci designed a man-shaped machine to look like a knight in 1464. It would be controlled with ropes and wheels. Other engineers and dreamers drew mechanical men. In1920, Karel Čapek wrote a story about them, and he used a word from Czech that is connected with 'work': robot.

The most successful robot designs in the 20th century were not made to look like people. They were designed for use. George Devol made the first of these, the , in 1954, with one arm and one hand. General Motors bought it in 1960. The next year, it started work in a factory in New Jersey, lifting and stacking pieces of metal that were too hot for people to touch. The engineers could program it, and reprogram it if they had to. Modern robots

Industrial robot, used for welding

Robots have many uses. Many factories use robots to do hard work quickly and without many mistakes. They do not look like people, because they are made to do things. These are 'industrial' robots. Some robots find and get rid of bombs. If someone makes a mistake, the robot is damaged or destroyed, which is better than a person being killed. There are also robots that help at home, to vacuum or run a lawn mower, for example. Such robots must learn about the area of work.

A few robots do surgery in places inside the body where a human hand is too big.

Planet rovers are robots for exploring distant planets. Because it takes a long time to send a radio signal from Earth to another planet, the robots do much of their work alone, without commands from Earth.

People still think of robots as having a shape like a person—two legs, two arms, and a head. ASIMO is one robot that is helping scientists learn how to design and program robots. It can walk, which is not easy to program. Types of robots

The quadrupedal robot Cheetah, an evolution of BigDog (pictured), was clocked as the world's fastest in 2012, beating the record set by an MIT bipedal robot in 1989.

The Care-Providing Robot FRIEND

Autonomous robots – robots that are not controlled by humans:

– robot capable of independent flight on other planets  – ; resembling the shape or form of a human  – early self-operating robot, performing exactly the same actions, over and over  Autonomous vehicle – vehicle equipped with an autopilot system, which is capable of driving from one point to another without input from a human operator  Ballbot – dynamically-stable designed to balance on a single spherical wheel (i.e., a ball)  – also known as a cybernetic organism, a being with both biological and artificial (e.g. electronic, mechanical or robotic) parts  Explosive ordnance disposal robot – mobile robot designed to assess whether an object contains explosives; some carry detonators that can be deposited at the object and activated after the robot withdraws  – humanoid robot designed to look like a human female  (walker) – a six-legged robot, using a simple insect-like locomotion  – reprogrammable, multifunctional designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks o 3D printer  Insect robot – small robot designed to imitate insect behaviors rather than complex human behaviors.  Microbot – microscopic robots designed to go into the human body and cure diseases  – exosuit which is capable of merging with its user for enhanced strength, speed, handling, etc.  Mobile robot – self-propelled and self-contained robot that is capable of moving over a mechanically unconstrained course. o Cruise missile – robot-controlled guided missile that carries an explosive payload.  Music – robot created to perform music entertainment by playing custom made instrument or human developed instruments.  Nanobot – the same as a microbot, but smaller. The components are at or close to the scale of a nanometer (10−9 meters).  Prosthetic robot – programmable manipulator or device replacing a missing human limb.  Rover – a robot with wheels designed to walk on other planets' terrain  – machines that extend human capabilities.  Snakebot – robot or robotic component resembling a tentacle or elephant's trunk, where many small actuators are used to allow continuous curved motion of a robot component, with many degrees of freedom. This is usually applied to snake-arm robots, which use this as a flexible manipulator. A rarer application is the snakebot, where the entire robot is mobile and snake-like, so as to gain access through narrow spaces.  Surgical robot – remote manipulator used for keyhole surgery  Walking robot – robot capable of locomotion by walking. Owing to the difficulties of balance, two-legged walking robots have so far been rare, and most walking robots have used insect-like multilegged walking gaits.

By mode of locomotion

Mobile robots may be classified by:

 The environment in which they travel: o Land or home robots. They are most commonly wheeled, but also include legged robots with two or more legs (humanoid, or resembling animals or insects). o Aerial robots are usually referred to as unmanned aerial vehicles (UAVs). o Underwater robots are usually called autonomous underwater vehicles (AUVs). o Polar robots, designed to navigate icy, crevasse filled environments  The device they use to move, mainly: o Legged robot – human-like legs (i.e. an android) or animal-like legs o Tracks o Wheeled robot Eastern and western views

Eastern thoughts on robots

Roughly half of all the robots in the world are in Asia, 32% in Europe, and 16% in North America, 1% in Australasia and 1% in Africa. 30% of all the robots in the world are in Japan. Japan has the most robots of any country in the world, and is the leader in the world industry. Japan is actually said to be the robotic capital of the world.

In Japan and , ideas of future robots have been mainly positive. The positive reception of robots there may be partly because of the famous cartoon robot, 'Astroboy'. China expressed views on robotics that are similar to those of Japan and South Korea, but China is behind both America and Europe in robotic development. The East Asian view is that robots should be roughly equal to humans. They feel robots could care for old people, teach children, or serve as assistants. The popular opinion of East Asia is that it would be good for robots to become more popular and more advanced. This view is opposite to the popular Western view.

"This is the opening of an era in which human beings and robots can co-exist," says Japanese firm Mitsubishi about one of the many human-like robots in Japan. The South Korean Ministry of Information and Communication has predicted that every South Korean household will have a robot by between 2015 and 2020.

Western thoughts on robots

Robot gunman

Western societies are more likely to be against, or even fear the development of robots. movies and other stories often show them as dangerous rebels against humanity.

The West regards robots as a 'threat' to the future of humans, which is much due to religious influence of the Abrahamic , in which creating machines that can think for themselves would almost be playing God. Obviously, these boundaries are not clear, but there is a significant difference between the two ideologies. Robot Laws

The writer Isaac Asimov told many stories about robots who had the three to keep humans safe from them.

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2. A robot must obey orders given to it by human beings, except where such orders would conflict with the . 3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

These were not used in real life when he invented them. However, in today's world robots are more complicated, and one day real laws may be needed, much like Isaac Asimov's original three laws.

These laws are talked about in the Megaman video games.

South Korea was the first country in the world to have laws about robots. Related pages
