What is the Smart Skin for Exploration Cobots and what is its main purpose?

The Smart Skin is a multifunctional 3D-printed coating designed for robotic arms in lunar and Martian missions. Its purpose is to integrate thermal protection, sensors, and wiring into a single flexible solution, overcoming the limitations of traditional multilayer insulation systems designed for static surfaces.

What are the four integrated functions of the smart skin?

The four functions are: thermal and dust protection against temperatures from -150°C to 120°C, flexible transfer of power and data through integrated wiring, distributed sensors to detect collisions and abnormal pressures, and interfaces for human-machine interaction with astronauts.

Why are traditional MLI systems unsuitable for robotic arms and how does the Smart Skin overcome them?

Traditional MLI systems are designed for static surfaces and do not adapt to the movements, bending, and rotations of robotic arms, which are also exposed to abrasive dust and thermal shocks. The Smart Skin overcomes these limitations by being a flexible and adaptable coating, made with 3D-printed geometries that follow movements without compromising protection.

Who leads the project and which partners are part of it?

The project is led by the Danish Technological Institute with a consortium that includes Admatis from Hungary, PIAP Space from Poland, and Redwire Space Europe from Luxembourg. The expected duration is two years, with the goal of delivering two functional solutions tested in simulated space conditions.

What materials and technologies are used to create the flexible structure?

The structure is based on a 3D-printed scaffold that serves as a framework to integrate advanced polymers, printed electronics, and e-textile. These technologies allow sensors and conductive tracks to be distributed on flexible surfaces that follow folds and movements better than rigid solutions, reducing bulk and weight.

How do the distributed sensors in the skin improve safety and interaction with astronauts?

The sensors allow the robot to perceive contacts, impacts, and environmental conditions directly on the arm's surface, improving situational awareness that cameras and LIDAR cannot guarantee alone. This capability reduces the risk of dangerous movements near astronauts and prevents damage to fragile components, also serving as a physical interface for more immediate interaction.

The smart skin that protects robots in space?

The intelligent skin that protects robots in space

The European Space Agency has launched a 1.65 million euro project to develop a 3D-printed “smart skin” for the robotic arms of future lunar and Martian missions. The system, called Smart Skin for Exploration Cobots, integrates thermal protection, sensors, and wiring into a single flexible coating.

The project aims to overcome the limits of traditional multi-layer insulation (MLI) systems, designed for static surfaces, by creating an adaptable protection for moving robotic components.

What is Smart Skin and why is it revolutionary

Smart Skin is a multifunctional coating built around a 3D-printed scaffold. It is mounted on robotic arms and performs four functions simultaneously.

The system represents a change in approach compared to traditional solutions. Space robots have so far used MLI materials for thermal protection, but these coatings only work on fixed surfaces. A robotic arm moves, bends, rotates, and is exposed to abrasive dust and extreme temperature swings.

The four integrated functions

Thermal and dust protection against temperatures from -150°C to 120°C
Flexible power and data passage through integrated wiring
Distributed sensors to detect collisions and abnormal pressures
Interfaces for human-machine interaction with astronauts

The Danish Technological Institute leads the project with a consortium that includes Admatis (Hungary), PIAP Space (Poland) and Redwire Space Europe (Luxembourg). The expected duration is two years, with the goal of delivering two functional solutions tested in simulated space conditions.

Materials and design architecture

The 3D-printed structure serves as a scaffold to integrate advanced polymers, printed electronics, and e-textiles into a flexible yet controlled system.

3D printing allows the creation of complex geometries that follow the movements of the robotic arm without compromising protection. Admatis develops the thermal protection, while PIAP Space and Redwire Space Europe provide the real robotic arms used in ESA lunar missions.

Printed electronics and e-textiles play a central role. These technologies enable the distribution of sensors and conductive tracks on flexible surfaces. E-textiles follow folds and movements better than rigid solutions, reducing bulk and weight.

The main challenge is bringing flexible electronics into space. The system must withstand radiation, vacuum, mechanical fatigue, and ensure adhesion between different layers. The printed structure serves to bring order to a system that must remain flexible yet controlled.

Sensors and electronic integration

Sensors distributed in the skin allow the robot to perceive contacts, impacts, and environmental conditions, making safe collaboration with astronauts possible and preventing damage to delicate instruments.

A space robot can be controlled remotely, execute autonomous sequences, or collaborate with humans. In all cases, perception of the environment is essential. Cameras and LIDAR provide important information, but they are not enough to understand what is happening on the surface of the arm.

A sensorized skin detects contacts, abnormal pressures, or conditions that suggest a risk of collision. For a robot working alongside an astronaut, this capability reduces the risk of dangerous movements. For a robot operating on a lunar base or near a satellite, it can prevent damage to solar panels, antennas, or fragile components.

The project also addresses the theme of HRI (Human-Robot Interface). A skin can become a physical interface, with signals or sensitive surfaces that allow the astronaut to understand the robot's state and interact more directly.

Technical note

The advantage of printed electronics lies in the distribution of the function: not a single sensor in one point, but a surface that actively participates in the robot's behavior.

Space testing and industrial perspectives

The system will be tested in thermal chambers and space environmental simulations to validate the durability, dust protection, and reliability of the integrated sensors during repeated motion cycles.

The project is based on a pilot phase already successfully completed. The robotic arms provided by the partners are the same ones currently in development for ESA lunar missions, ensuring that the protection is designed taking into account the dimensions, joints, and real requirements.
