From Hugvie to Sylvie

Simple, soft shapes are everywhere. In our home environment you can find pillows, blankets, balls, bottles, clothes, etc. Robots are often expensive and complex. But couldn’t they be thought of in a completely different way? How could social robots emerge from simple, soft shapes? As part of their final thesis at the School of Business FHNW, Nhi Tran Hoang Yen and Thang Hoang Vu from Ho Chi Minh City have answered this question posed by their supervisor Prof. Oliver Bendel. They have submitted eleven proposals for novel robots. All are shown on informationsethik.net. The seventh proposal is Sylvie. The normal Hugvie is a communication and hugging device, whereby the communication is not with it, but with friends, partners and family members. Sylvie is a variant of it. You talk directly to her, and when you hug her, you mean her, not a human being. And there’s another difference: while in the classic Hugvie the smartphone is invisibly housed in a pocket on the head, in Sylvie it forms part of the face. A video is available here.

The New Life of Hugvie

How can you make social robots out of simple, soft shapes and objects, i.e. robots for interacting with people and animals? Under the supervision of Prof. Dr. Oliver Bendel, Vietnamese students Nhi Hoang Yen Tran and Thang Vu Hoang are investigating this question in the project “Simple, Soft Social Robots” at the School of Business FHNW. They are using Hugvie from the Hiroshi Ishiguro Laboratories as a basis – these labs are particularly famous for the Geminoid and for Erica. But hugging robots like Telenoid also come from them. The latest product from this series is Hugvie. A pocket for a smartphone is attached to its head. People who are far away from each other can talk to each other and have the feeling of hugging and feeling each other. But what else can you do with Hugvie and similar forms? Can you make them conversationalists themselves, can you teach them to move their limbs and be active in other ways? And what does such robotization of simple, soft forms and objects mean for everyday life and society?

A Prod, a Stroke, or a Hug?

Soft robots with transparent artificial skin can detect human touch with internal cameras and differentiate between a prod, a stroke, or a hug. This is what New Scientist writes in its article “Robot that looks like a bin bag can understand what a hug is“. According to the magazine, the technology could lead to better non-verbal communication between humans and robots. What is behind this message? A scientific experiment that is indeed very interesting. “Guy Hoffman and his colleagues at Cornell University, New York, created a prototype robot with nylon skin stretched over a 1.2-metre tall cylindrical scaffold atop a platform on wheels. Inside the cylinder sits a commercial USB camera which is used to interpret different types of touch on the nylon.” (New Scientist, 29 January 2021) In recent years, there have been several prototypes, studies and surveys on hugging robots. For example, the projects with PR2, Hugvie, and HUGGIE are worth mentioning. Cornell University’s research certainly represents another milestone in this context and in a way puts humans in the foreground.

Simple, Soft Social Robots

With Hugvie and Somnox Sleep Robot, researchers and companies has made it clear that it is possible to build simple, soft social robots that have a certain utility and impact. This raises hopes for social robotics, which is currently showing some progress, but is still developing slowly. Materials such as rubber and plastic can be used to make simple, soft social robots. These materials can be combined with existing devices such as smartphones and tablets on which you run certain applications, or with simple sensors and electronic components. The project or thesis, announced by Oliver Bendel in 2020 at the School of Business FHNW, will first do research on the basics of simple, soft social robots. The work of Hiroshi Ishiguro and Alexis Block (with Katherine J. Kuchenbecker) will be included. Then, examples of implementation forms are mentioned and sketched. Their purpose and benefits are presented, as well as possible areas of application. One example is to be implemented, whereby speech abilities and sounds can be an option as well as vibration and electrical impulses. The reference to applications in the household, in public space or in the commercial sector should be established. The project will start in March 2021.
