These fields are from the surface of the robot called H1. The robot was developed by the Technical University of Munich. The fields on the surface always have 6 corners. It is easy to put them together to form larger pieces.

In 2019, the robot H1 got these fields as the skin on its upper body, arms and legs. The skin consists of more than a thousand pieces of these fields. The skin is called e-skin500. E-skin means: electronic skin. You can also say artificial skin.

Each field of the artificial skin is a separate unit. The fields are next to each other and exchange information. Just like human skin, the artificial skin can sense touch and temperature. The electronic sensors even work when a single field is not functioning.

The invention of this artificial skin was new. Until then, robots had no surface that could feel. The e-skin500 can save a lot of energy: The artificial skin only reacts when it really feels a touch.

Robots with this artificial skin are very safe. That is why they can be used, for example, in old people's homes or in hospitals to care for people.
