 Scientists are already developing the Internet < /p>

Researchers led by Qi Zhang, assistant professor in the Department of Electrical and Computer Engineering at Aarhus University, have launched a research project called eTouch to overcome the limitations of modern technology in the future data transmission. More specifically, they seek to provide real-time tactile sensations without perceptible delay, regardless of distance. The project will start in 2022 and will run for three years, sponsored by the Danish Independent Research Foundation, writes SciTech Daily.

According to scientists, the so-called Internet of skills should appear in the future – in it all the skills of people will be digitized. With the help of haptic feedback, specialists will be able to remotely control avatar robots, as if with their own body, for example, a surgeon will be able to feel a scalpel and perform operations while he is physically in another country.

The problem is that the current speed of the Internet is not enough to fully control robots at a great distance – even light “slows down” over time. in fiber, which reduces the response time of the machine to operator actions. To trick the skin and body into perceiving virtual sensations as real, the delay must be less than one millisecond (0.001 seconds). Ultra-high bandwidth fiber optic networks with ultra-low latency of one thousandth of a second already exist, but they can achieve high speeds over a distance of up to 150 km and only under ideal conditions.

mediated teleoperation, in which the virtual model (digital twin) will accurately describe the remote environment and instantly create haptic feedback locally without the need to send signals over long distances. The modern concept of the Internet does not allow to create a sufficiently accurate model, so the engineers decided to use edge computing (Edge Computing), a distributed computing paradigm carried out within the reach of end devices, which provides for faster network response times and more efficient use of network bandwidth.
