There is a consensus on how to make better robots.
Many experts say future factory applications should not be designed for physical strength or from the ability to make a toaster to make a car.
Instead, they suggest that robots should be tasks.
Specific and sensitive, able to see and feel, and able to use information to maintain \"intelligence\" that adapts to the inexact environment of the factory workshop as humans do \".
Warren Seering, a professor of mechanical engineering at MIT, observed that robots are still limited to simple tasks.
Now 6,200 of the conventional industrial operations in the United States, most of them perform relatively rough functions such as painting and spot welding.
Professor Selin said that the assembly of parts has the greatest hope for growth, but Assembly depends on human subtle skills: the ability to respond to feedback.
Therefore, it is possible to imitate the way in which one person connects one part to the other --
Through visual, tactile and corrective actions
It is crucial to the progress of robots.
Some companies say they will have highly accurate robots.
Pittsburgh has started selling a machine that says it is fast and accurate in one machine
A few parts per thousand.
According to its literature, this machine, called Merlin, shot seven needles with a needle-
A few inches wide across the eyes of another needle
A few inches wide, not touching the side.
Advertising but Victor Scheinman, vice president of automix, said those who believe in more accuracy missed the ship. Mr.
Scheinman developed the original commercial robot, the programmable general assembly machine known as PUMA.
The most important requirements of robots in assembly tasks
This is its interface capability with the real world, which is not entirely accurate, says Schinman.
\"Robots in the future\" may not be accurate than robots now, but their lack of precision will get better sensors and more intelligent compensation, he said.
\"Laura Connery, Prudential analyst --
Complex robot skills may be necessary, but not enough, says Bache Securities.
She says robots must be seen only as peripheral devices for computers --
As a unit of a well
Integrated manufacturing system
Its suppliers must fully understand the needs of their customers and provide a wide range of services.

Therefore, the application of robots in products
Companies with rich robot experience may increasingly dominate assembly tasks.
The 7565 manufacturing system of the international commercial machine company has tactile and visual sensors on the robot arm. I. B. M.
Display the force of the system-
By allowing it to execute the long-term perception capabilities of robot manufacturers
Long awaited power tour: pick up an egg gently but firmly and break it at the hint. But I. B. M.
James McDonald, director of the company\'s industrial automation division, said the company\'s machines are well beyond the demo stage.
For example, Boeing has used them to assemble electronic components, and general power has used some I. B. M.

The Weldvision robot launched by GE in April also impressed the robot world, which uses lasers
Arc welding based on the visual system is a more complex task than resistance welding, even if the parts to be connected show great irregularities.
\"It\'s a real breakthrough,\" said Larry Sweet, G. \'S control theory and systems program manager. E.
Because it is the first production robot that can perceive changes and correct them in real time like humans.
Professor Selin said that although the designer of the robot system tried to simulate the feedback process used by humans in assembly tasks, the product also needed significant changes so that the robot could assemble the parts more easily.
It\'s boring, he says, so everyone wants to buy a robot solution.
But the redesign of products and processes may be more important than the evolution of robots themselves.
Richard beeccher, GM\'s robotics department manager, says the most satisfying change will involve culture, not technology or products --design factors.
The ultimate problem, he said, is not a shortage of technology, but a creative person and risk taker.
