“industrial-robot experts” are those who have some experience of “touching” industrial robots ?
“touching” industrial robots is the beginning of developing industrial robots, not the end.
Some people tear off industrial robots until they can find their familiar pieces such as kinematics, dynamics, control, power electronics, operating system, programming language, and so on. And then, they claim “I do industrial robots, too.”
R & D of industrial robots may start with identifying the vital pieces of industrial robots. Simply taking good stuffs from other areas and combining them, results in a Chimera (in Greek myth, the Chimera is a fire-breathing creature that has the body of a goat, the head of a lion and the tail of a serpent ).
Aristoteles said, “The whole is greater than the sum of its parts.” What turns the sum of individual parts or pieces into the whole ?
Fortunately, we do not need to re-invent industrial robots. Industrial robots has been aound for more than 40 years. “Industrial-robot experts” already know what are good or bad for industrial robots.
