Robotics is the science and technology of robots, their design, manufacture, and application. Robotics requires a working knowledge of electronics, mechanics and software, and is usually accompanied by a large working knowledge of many subjects. A person working in the field is a roboticist.
Although the appearance and capabilities of robots vary vastly, all robots share the features of a mechanical, movable structure under some form of autonomous control. The structure of a robot is usually mostly mechanical and can be called a kinematic chain (its functionality being similar to the skeleton of the human body). The chain is formed of links (its bones), actuators (its muscles) and joints which can allow one or more degrees of freedom. Most contemporary robots use open serial chains in which each link connects the one before to the one after it. These robots are called serial robots and often resemble the human arm. Some robots, such as the Stewart platform, use closed parallel kinematic chains.
A robot is mechanical intelligent agent which can perform tasks on its own or with guidance. In practice a robot is usually an electro mechanical machine which is guided by computer and electronic programming. Robots can be autonomous or semi-autonomous and come in those two types: those which are used for research into human-like systems such as ASIMO and TOPIO as well as those into more defined and specific roles such as Nano robots, Swarm robots; and helper robots used for performing dangerous tasks such as industrial robots etc.
ASIMO is a created by Honda. Standing at 130 centimeters (4 feet 3 inches) and weighing 54 kilograms (119 pounds) the robot resembles a small astronaut wearing a backpack and can walk or run on two feet at speeds up to 6 km/h (3.7 mph)....
