ETH focus project: «SpaceHopper»25.07.2022
Carbon reinforced 3D printing: Scheurer Swiss GmbH supports ETH Zurich in the development of an innovative hopping robot for exploring asteroids.
The engineering company Scheurer Swiss GmbH, known for its long-standing expertise with fibre composite technologies, is supporting the focus project “SpaceHopper” of the Swiss Federal Institute of Technology (ETH) Zurich with its engineering know-how, printing carbon reinforced robot components and using its extensive network to connect the project team with other companies to complete the unique robot. The revolutionary three-legged hopping robot is specifically designed for controlled locomotion in zero gravity and is expected to provide new opportunities for asteroid exploration. After only eight months of development, the first prototype was successfully presented at the end of May.
The difficult, especially weightless, environment of astronomical small bodies requires a new, unique research solution. The “SpaceHopper” robotics project supported by Scheurer Swiss aims to be just that. With the support of experts from research, industry and lightweight construction, the ten budding engineers from ETH Zurich and ZHAW have developed and built the revolutionary mobility platform: A three-legged hopping robot with carbon reinforced components from the 3D printer, lightweight and stable, the design optimized for low gravity hopping.
“One of the challenges was to make the legs as thin-walled as possible to minimize the overall weight of the robot. Nevertheless, they have to withstand the forces of the bouncing impact,” explains Mechanical Designer, Emma Steinke, and emphasizes, “We are glad to have Scheurer Swiss on our side as a lightweight design expert. The competent expertise around state-of-the-art fibre composite technologies and 3D printing as well as the large network of Scheurer Swiss were very valuable for us and contributed to the success of our focus project from the very beginning.”
Scheurer Swiss CEO, Dominik Scheurer, points out, “Carbon reinforced 3D printing is ideally suited for the robotic components because virtually any shape can be produced. Hollow bodies, such as the robot’s legs, can be provided with support structures to stabilize them without weighing them down unnecessarily. Additive manufacturing is the ideal manufacturing process for this, and it’s very cost-effective.”
A special feature of additive manufacturing is that objects are manufactured directly on the basis of 3D computer data, so-called rapid product development. In particular, components with a high degree of customization can be produced promptly and cost-effectively with the necessary stability and functionality. Scheurer, the lightweight construction expert, is certain: “3D printing is currently one of the most modern lightweight construction technologies and is shaping the future of the manufacturing industry like hardly any other process. The intention is clear: even more flexibility, creativity and cost efficiency in product development.
Thanks to its roots in Formula 1 motorsport, Scheurer Swiss has over thirty years of experience in the field of lightweight construction and is the only provider in Switzerland to offer a complete service: from consulting, design and engineering to production – all from a single source. We will be happy to advise you!
