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. Robotics are human like due to the structures that very closely resemble that of the human body structure, only in a metallic form. The body is called a kinematic chain, which is formed of links similar to the bones of the human body, actuators like the muscles, and joints which can be allowed more than one degree of freedom. The word robotics was first used in print by Isaac Asimov, in his short science fiction story "Runaround", published in March of 1942 in Astounding Science Fiction. Although his word was based upon the word "robot" which was coined by Karel Capek, he was still known for coining the term "robotics". The term is defined as the design of robots just as the design of electrical devices is known as electronics.

Robotics has become more and more simplified since the technology has expanded. Many robots can be controlled with very simple controllers and programmed with point and click graphical user interfaces. The size of the robots has decreased dramatically. The first group of robots being the size of a room and to the latest controllers fitting into your hand. Not to mention the costs of parts of machinery needed has dropped. Robots are becoming more easy to make and more cost efficient.

Human interaction

Robots in Our Everyday Life
Like we have all been told, technology is nothing if it can't increase productivity and applied to everyday life. Since Robots would be used by a variety of groups, they must be designed to interact effectively with the group with the least amount of training. It is thus imperative that they be extremely intuitive and be able to cover a wide margin of error. Speech would obviously be the easiet way for the user to communicate with the robot, but because it is so unnatural for the robot command lines are the compromise. Other complications, improvements, and compromises are outlined below:
  • Speech Recognition : Davis, Biddulph, and Balashek are responsible for a huge breakthrough in speech recognition technlogy. they designed the first "voice imput system" which recognized "ten digits spoken by a single user with 100% accuracy" in 1952. Currently, the best systems can compute up to 160 natural speech words with 95% accuracy. 48 47
  • Gestures : Hand gestures are a vital form of human communication. While a great many systems have been developed to aid robots in recognizing human hand gestures there is still so much more. This could be one of the most effective ways for humans to interact with robots.
  • Facial Expression : See the picture below: Kismet Robot was designed to help research the human expressions. It was created with auditory, visual, and expressive systems to show the different moods and expressions humans feel.

Different types of robotics include:

  • Walking Robots
  • Rolling Robots
  • Flying Robots
  • Human Interactive Robots
  • Stationary Robots
  • Autonomous Robots
  • Remote-Controlled Robots


kinematic chain
: is a branch of dynamics which describes the motion of objects without the consideration of the masses or forces that bring about the motion.
graphical user interface: or GUI (IPA: /ˈɡuːiː/) is a type of user interface which allows people to interact with a computer and computer-controlled devices. It presents graphical icons, visual indicators or special graphical elements called "widgets".
