The early s saw remotely controlled torpedoes by John Ericsson pneumatic , John Louis Lay electric wire guided , and Victor von Scheliha electric wire guided. The Brennan torpedo , invented by Louis Brennan in , was powered by two contra-rotating propellors that were spun by rapidly pulling out wires from drums wound inside the torpedo. Differential speed on the wires connected to the shore station allowed the torpedo to be guided to its target, making it "the world's first practical guided missile".
Archibald Low , known as the "father of radio guidance systems" for his pioneering work on guided rockets and planes during the First World War. In , he demonstrated a remote controlled aircraft to the Royal Flying Corps and in the same year built the first wire-guided rocket. English pronunciation of the word has evolved relatively quickly since its introduction. In the U. In , one of the first humanoid robots, Eric , was exhibited at the annual exhibition of the Model Engineers Society in London , where it delivered a speech.
Invented by W. Richards, the robot's frame consisted of an aluminium body of armour with eleven electromagnets and one motor powered by a twelve-volt power source. The robot could move its hands and head and could be controlled through remote control or voice control. Westinghouse Electric Corporation built Televox in ; it was a cardboard cutout connected to various devices which users could turn on and off.
The body consisted of a steel gear, cam and motor skeleton covered by an aluminum skin. In , Japan's first robot, Gakutensoku , was designed and constructed by biologist Makoto Nishimura.

The first electronic autonomous robots with complex behaviour were created by William Grey Walter of the Burden Neurological Institute at Bristol , England in and He wanted to prove that rich connections between a small number of brain cells could give rise to very complex behaviors — essentially that the secret of how the brain worked lay in how it was wired up. His first robots, named Elmer and Elsie , were constructed between and and were often described as tortoises due to their shape and slow rate of movement.
The three-wheeled tortoise robots were capable of phototaxis , by which they could find their way to a recharging station when they ran low on battery power. Walter stressed the importance of using purely analogue electronics to simulate brain processes at a time when his contemporaries such as Alan Turing and John von Neumann were all turning towards a view of mental processes in terms of digital computation. His work inspired subsequent generations of robotics researchers such as Rodney Brooks , Hans Moravec and Mark Tilden.
The first digitally operated and programmable robot was invented by George Devol in and was ultimately called the Unimate. This ultimately laid the foundations of the modern robotics industry. The first palletizing robot was introduced in by the Fuji Yusoki Kogyo Company. Commercial and industrial robots are now in widespread use performing jobs more cheaply or with greater accuracy and reliability than humans. They are also employed for jobs which are too dirty, dangerous or dull to be suitable for humans.
Robots are widely used in manufacturing, assembly and packing, transport, earth and space exploration, surgery, weaponry, laboratory research, and mass production of consumer and industrial goods. Various techniques have emerged to develop the science of robotics and robots.
One method is evolutionary robotics , in which a number of differing robots are submitted to tests. Those which perform best are used as a model to create a subsequent "generation" of robots. Another method is developmental robotics , which tracks changes and development within a single robot in the areas of problem-solving and other functions. Another new type of robot is just recently introduced which acts both as a smartphone and robot and is named RoboHon.
As robots become more advanced, eventually there may be a standard computer operating system designed mainly for robots. Robot Operating System is an open-source set of programs being developed at Stanford University , the Massachusetts Institute of Technology and the Technical University of Munich , Germany, among others. ROS provides ways to program a robot's navigation and limbs regardless of the specific hardware involved. It also provides high-level commands for items like image recognition and even opening doors.

When ROS boots up on a robot's computer, it would obtain data on attributes such as the length and movement of robots' limbs. It would relay this data to higher-level algorithms. Microsoft is also developing a "Windows for robots" system with its Robotics Developer Studio, which has been available since Japan hopes to have full-scale commercialization of service robots by Much technological research in Japan is led by Japanese government agencies, particularly the Trade Ministry. Many future applications of robotics seem obvious to people, even though they are well beyond the capabilities of robots available at the time of the prediction.

In , these Caterpillar trucks were actively used in mining operations in Australia by the mining company Rio Tinto Coal Australia.
A literate or 'reading robot' named Marge has intelligence that comes from software. She can read newspapers, find and correct misspelled words, learn about banks like Barclays, and understand that some restaurants are better places to eat than others. Baxter is a new robot introduced in which learns by guidance. A worker could teach Baxter how to perform a task by moving its hands in the desired motion and having Baxter memorize them.
Extra dials, buttons, and controls are available on Baxter's arm for more precision and features. Any regular worker could program Baxter and it only takes a matter of minutes, unlike usual industrial robots that take extensive programs and coding in order to be used. This means Baxter needs no programming in order to operate. No software engineers are needed. This also means Baxter can be taught to perform multiple, more complicated tasks. Sawyer was added in for smaller, more precise tasks. Rossum's Universal Robots , published in The play does not focus in detail on the technology behind the creation of these living creatures, but in their appearance they prefigure modern ideas of androids , creatures who can be mistaken for humans.
These mass-produced workers are depicted as efficient but emotionless, incapable of original thinking and indifferent to self-preservation. At issue is whether the robots are being exploited and the consequences of human dependence upon commodified labor especially after a number of specially-formulated robots achieve self-awareness and incite robots all around the world to rise up against the humans.
However, he did not like the word, and sought advice from his brother Josef, who suggested "roboti". Robot is cognate with the German root Arbeit work.
The word robotics , used to describe this field of study,  was coined by the science fiction writer Isaac Asimov. Asimov created the " Three Laws of Robotics " which are a recurring theme in his books. These have since been used by many others to define laws used in fiction. The three laws are pure fiction, and no technology yet created has the ability to understand or follow them, and in fact most robots serve military purposes, which run quite contrary to the first law and often the third law.
If you read the short stories, every single one is about a failure, and they are totally impractical," said Dr. Joanna Bryson of the University of Bath. Mobile robots  have the capability to move around in their environment and are not fixed to one physical location. An example of a mobile robot that is in common use today is the automated guided vehicle or automatic guided vehicle AGV. An AGV is a mobile robot that follows markers or wires in the floor, or uses vision or lasers. Mobile robots are also found in industry, military and security environments.
Mobile robots are the focus of a great deal of current research and almost every major university has one or more labs that focus on mobile robot research. Mobile robots are usually used in tightly controlled environments such as on assembly lines because they have difficulty responding to unexpected interference. Because of this most humans rarely encounter robots. However domestic robots for cleaning and maintenance are increasingly common in and around homes in developed countries.
Robots can also be found in military applications. Industrial robots usually consist of a jointed arm multi-linked manipulator and an end effector that is attached to a fixed surface. One of the most common type of end effector is a gripper assembly. The International Organization for Standardization gives a definition of a manipulating industrial robot in ISO :.
Most commonly industrial robots are fixed robotic arms and manipulators used primarily for production and distribution of goods. The term "service robot" is less well-defined. The International Federation of Robotics has proposed a tentative definition, "A service robot is a robot which operates semi- or fully autonomously to perform services useful to the well-being of humans and equipment, excluding manufacturing operations. Robots are used as educational assistants to teachers.
From the s, robots such as turtles were used in schools and programmed using the Logo language. Robotics have also been introduced into the lives of elementary and high school students in the form of robot competitions with the company FIRST For Inspiration and Recognition of Science and Technology. There have also been robots such as the teaching computer, Leachim Modular robots are a new breed of robots that are designed to increase the utilization of robots by modularizing their architecture.

These robots are composed of a single type of identical, several different identical module types, or similarly shaped modules, which vary in size. Their architectural structure allows hyper-redundancy for modular robots, as they can be designed with more than 8 degrees of freedom DOF.
Creating the programming, inverse kinematics and dynamics for modular robots is more complex than with traditional robots. Modular robots may be composed of L-shaped modules, cubic modules, and U and H-shaped modules. These "ANAT robots" can be designed with "n" DOF as each module is a complete motorized robotic system that folds relatively to the modules connected before and after it in its chain, and therefore a single module allows one degree of freedom.
The more modules that are connected to one another, the more degrees of freedom it will have. L-shaped modules can also be designed in a chain, and must become increasingly smaller as the size of the chain increases, as payloads attached to the end of the chain place a greater strain on modules that are further from the base.
