successive steps of a given operation according to a predetermined sequence, condition, and position, and whose set information cannot be easily changed.
3) variable sequence robot-- a manipulator which repetitively performs successive steps of a given operation according to a predetermined sequence, condition, and position, and whose set information can be easily changed.
4) playback robot-- a manipulator which can produce, from memory, operations originally executed under human control. A human operator initially operates the robot in order to input instructions. All the infor- mation relevant to the operations (sequence, conditions, and positions ) is
put in memory. hence, its name) from memory.
When needed, this information is recalled (or played back, and the operations are repetitively executed automatically
5) NC (numerical control) robot-- a manipulator that can perform a given task according to the sequence, conditions and position, as commanded
via numerical data. The software used for these robots include punched tapes, cards, and digital switches. This robot has the same control mode as an N. C. machine.
6) intelligent robot-- this robot with sensory perception (visual and /or tactile) can detect changes by itself in the work environment or work condition and, by its own decision-making faculty, proceed with its operation accordingly.
I have used three different robot definitions:
“Robots by Japanese Definition ’’--all 6 classes
“Robots by U.S. Definition ’’--classes 3,4, 5,6
“Sophisticated Robots ’’--classes 4,5,6
The American Robot Industry Association (RIA) defines a robot as “a manipulator designed to move material, parts, tools, or specialized devices, through variable programmed motions for the performance of a variety of tasks. “ Thus, the U.S. definition of robots eliminates the manual mani- pulators and fixed sequence machines.
The following is a breakdown by the nature of input information and teaching (in yen value) .
