Man-robot manufacturing, big step opens up the future?

Ethical controversies are a major obstacle to human-robot ambitions, using only the human brain to maintain the operation of a completely artificial body.

Unlike all robots ever built, humans-robots will use the human brain as the command center. All the rest from the legs, arms to the heart, lungs or even the ears of the eyes are artificial products. Even the brain part is transplanted with computer chips, helping it improve human ability.

Human-robot manufacturing research helps life science keep up with science fiction, creating a new revolution to replace damaged human parts. If convenient, replacing human legs, arms or organs will have more options than relying on donors like today.

People-robots promise to make great strides.

Inheriting the results of billions of research works, social psychologist Bertolt Meyer is one of the pioneers to use artificial arms directly controlled by the brain. The arm used by Dr. Meyer is worth nearly $ 50,000, currently the most advanced product on the market.

Losing his left hand as a child, Dr. Meyer used many replacement parts before being selected to use the new method. Meyer said he had "personal interests" in "the explosion of innovation " six years ago. 'I think we are at a time when people can create their own perfect and special body.'

'When I grew up, I hated prosthetic hands because plastic hands with metal hooks were not useful in some cases. Some people even see it and show fear. Now, I feel my hand is part of my body. Without it, I felt I lacked something, ' Dr. Meyer said.

Parts of Rex.

However, the high-tech arm Meyer is using will soon become obsolete when a new technology product is put into use. The robot named Rex, worth $ 1 million, is made of the most advanced prosthetic devices, gathered from all the leading research labs around the world. Compared to Rex's arm, the performance that Dr. Meyer's arm is using is pretty much inferior.

With outstanding flexibility, the new generation robot arm is only slightly less than the flexibility and dexterity of the normal arm. When the artificial eye receives the image, the brain activates the processing before passing it to artificial muscles on the prosthetic arm, helping it know what to do. Meanwhile, the legs are also fitted with fake muscle layers, making it possible to operate like a human leg. The artificial heart of this robot works with storage batteries. The unfinished Rex robot will be on display at the London Science Museum on February 7.

In theory, Rex would be perfect, but the technological achievements that humans create can be a double-edged sword if we cross the limits of evolution. Professor of Bioethics and Human Rights at Boston University, he agrees with this view and says: 'It is very dangerous when we try to change what belongs to people'.
