What is “Robot”?

Recently, robotic field is interesting to explore. Many competitions have been presented by some countries to look for students whom has a good achievement in robotic field. There are many books that explained about robotic. We can learn robotic field from basic until advance.

The word “robot” originates from the Czech word for forced labor, or serf. It was introduced by playwright Karel Capek. Basically a robots consists of:
1. A mechanical device, such as a wheeled platform, arm, or other construction, capable of interacting with its environment.
2. Sensors on or around the device that are able to sense the environment and give useful feedback to the device
3. Systems that process sensory input in the context of the device’s current situation and instruct the device to perform actions in response to the situation.

In the manufacturing field, robot development has focused on engineering robotic arms that perform manufacturing processes. In the space industry, robotics focuses on highly specialized, one-of-kind planetary rovers. Unlike a highly automated manufacturing plant, a planetary rover operating on the dark side of the moon — without radio communication — might run into unexpected situations. At a minimum, a planetary rover must have some source of sensory input, some way of interpreting that input, and a way of modifying its actions to respond to a changing world. Furthermore, the need to sense and adapt to a partially unknown environment requires intelligence (in other words, artificial intelligence).

From military technology and space exploration to the health industry and commerce, the advantages of using robots have been realized to the point that they are becoming a part of our collective experience and every day lives.

They function to relieve us from danger and tedium:
1. Safety: Robotics have been developed to handle nuclear and radioactive chemicals for many different uses including nuclear weapons, power plants, environmental cleanup, and the processing of certain drugs.
2. Unpleasantness: Robots perform many tasks that are tedious and unpleasant, but necessary, such as welding or janitorial work.
3. Repetition and precision: Assembly line work has been one of the mainstays of the robotics industry. Robots are used extensively in manufacturing and, more glamorously, in space exploration, where minimum maintenance requirements are emphasize.
