Robotic Materials ETH Zürich in Switzerland

The Robotic Materials group  at ETH Zurich Department of Materials is looking for three postdocs and one PhD for the project funded by ERC Starting Grant : "Distributed Addressable Robotic Material via Wavelength-Division-Multiplexing (ColorfulAct)". ColorfulAct aims to establish the building blocks of physical intelligence parallel to nodes and connections to artificial intelligence. We will develop distributed and addressable robotic actuating materials that demonstrate multifunctionality through the broad bandwidth of light.

The Robotic Materials group headed by Prof. Hedan Bai at Department of Materials was established in October 2023. We are an international and interdisciplinary team of material scientists, roboticists, engineers and chemists with a passion for futuristic robotics. We take a bottom-up approach to robotics and develop soft materials and devices that would enable unusual form and unconventional functions for broader robotic applications.
