Ericsson-enabled 5G robot helps Danish teenager join classmates

Rasmus Dalsten (13), from Herlev, Denmark, lives a full day in the presence of his peers via a tablet with a live video connection from a 5G smartphone mounted on a fully mobile robot on the school grounds.

5G’s extremely low latency, fast speed, and high data processing capabilities mean that Rasmus, who is unable to physically go to school due to lung disease, not only does not lack activity in the classroom or in the schoolyard, but has the freedom to move around and watch where he wants.

Rasmus had an old robot that was controlled by teachers and classmates at school. If he wanted to change the view of what he was seeing, someone at school had to physically turn the robot in that direction.

With 5G, Rasmus has full control of the robot, called Fable, which is about the size of a small teddy bear. Wherever he wants to go, and whoever he wants to connect with at school, he controls Fable to become his eyes and ears in real time.

He can react to classroom lessons as they unfold by directing Fable himself. If anyone behind Fable makes a comment as part of a discussion, Rasmus can maneuver Fable to see who is speaking and even participate.

Rasmus says, “I have a new robot that I can spin around on my own and that’s not a problem for adults or for myself. It’s really good.”

Rasmus’ mother, Charlotte Dalsten, is in awe of the fact that Fable, which Rasmus tested for six months, allows her to make instant eye contact with her classmates.

“Rasmus connects to the PC and to the iPad, which is connected to the robot,” she says. “That way he can be with his class all day, during lunch breaks and in class. It was important for me to see that Rasmus is happy when he connects, that other people interact with him and that he is able to look around and make eye contact with them.

Rasmus teacher Cille explains that the 5G-powered robot allows Rasmus to take lessons on an equal basis with other classmates who are physically in the room.

“I’m not the one who decides if he looks at the board or if he looks at the people talking in the classroom,” she says. “He decides where to look and where to go. That’s what he would do if he was there physically. So that was clearly the biggest advantage. “

The 5G trial was born out of the collaboration between Danish communications service provider TDC Net, Danish robotics company Shape Robotics and Ericsson at the TDC / Ericsson 5G Innovation Hub in Denmark.

Ericsson, TDC Net and Shape Robotics say the trial proved the potential of using 5G-enabled mobile robotic connectivity in a multitude of use cases spanning home, work and industrial applications.

Moises Pacheco, CTO and co-founder of Shape Robotics, said: “Through collaboration with TDC NET and Ericsson, we have been able to show the potential of combining 5G technology with robots in an educational setting. Although Fable also works with 4G, in practice it is a different robot when using 5G. With 5G, students benefit from lightning-fast audio and image, allowing them to participate in the same conditions as other students. “

Toke Binzer, Vice President, Technology, Strategy and Economics, TDC NET, said: “It has been about a year since we launched the launch of the first national 5G network in Denmark. Since then, we have seen an increased interest in using technology to create value in many different industries. Robots connected to the 5G network can, unlike other robots, both send and receive large amounts of data without delay, while being remotely controllable. And if we take a step back from the education sector, it becomes clear that the lessons of this project can be transferred to other areas such as healthcare, social care and remote work in all areas. sectors.

Niclas Backlund, Director of Ericsson Denmark, says: “Denmark was one of the first countries in the world to deploy a 5G network nationwide. I am convinced that the example of the Danish robot, as well as the other initiatives that we have put in place with the 5G Innovation Hub, can inspire companies beyond our borders. 5G is proving to be a successful innovation platform for new use cases. This distance school app really shows the power of digitization to meet the needs of society and is a great example of digital inclusion.
