RoboTrust is an initiative of several research groups at the TU Darmstadt to shape the future of Human-Robot Interaction. In cooperation with the Goethe Universität Frankfurt and Universität Kassel we form a strong interdisciplinary team that can cover all relevant dimensions of a responsible digitalization regarding Psychology, AI and Robotics, Law and Context. As a pilot project, supported by the Centre Responsible Digitality, RoboTrust is investigating the necessary fundamentals for anthropomorphic robotic assistants to develop and evaluate uniform technological platforms.
