Robot: A robot is a mechanical, or virtual, artificial agent. It is usually an electromechanical system, which, by its appearance or movements, conveys a sense that it has intent or agency of its own. The word robot can refer to both physical robots and virtual software agents, but the latter are usually referred to as bots to differentiate.
Japanese Industrial Robot Association: The Japanese Industrial Robot Association (JIRA) recognizes as many as six classes of robots:
1: Manual: Handling Devices actuated by an operator
2: Fixed Sequence Robot
3: Variable-Sequence Robot with easily modified sequence of control
4: Playback Robot, which can record a motion for later playback
5: Numeric Control robots with a movement program to teach it tasks
6: Intelligent robot: that can understand its environment and able to complete a task despite changes in the operation conditions.
Because of the decrease in Japanís population, and also its history of karakuri, Japan is fascinated with robots.
