Planning and Human-Robot Interaction

The implementation of AI-based robotic applications that bring robots closer to humans in industrial and domestic environments is considered a grand challenge in robotics. For this, the seamless interaction, ranging from close physical collaboration during semi-autonomous telepresence to contact-aware motion and interaction planning in various environments needs to be realized. 

Contributions

Our group’s work on dynamic motion planning and collision avoidance led to several novel algorithms that can deal with complex and dynamic environments with moving obstacles and unforeseen contacts for full scale articulated robots [137]. One the one hand, our work centers around the idea of exploiting the emerging behavior of dynamical systems that are designed to respond to physical and virtual contacts [139] for dynamic maneuvers [74, 140], and extended by multi-agent predictions to reach more sophisticated and globally optimal behavior [144]. On the other hand, we exploit geometric aspects of the task via constrained motion and use it to design more robust and reliable trajectory generators that can be directly integrated with lower-level control [145, 146]. Based on such dynamic motion layers, task and interaction planners were developed that allow for humans and robots to collaborate, jointly perform a task such as assembly or simply safely coexist [147, 148]. Connecting robot motion to natural language interaction has also been an important goal of our work, as it is one of the most intuitive ways to express human intent. We proposed a flexible language-based framework that allows a user to modify generic robotic trajectories for intuitive human-robot interaction [150].

A further focus of our work is the development of tactile telepresence frameworks such as A-RIFT [151], which is a zero-cost interface globally accessible via consumer Internet. Moreover, we translated our results in shared interaction control to specialized telemedicine [152], and telerehabilitation [135] systems, enabling medical experts to safely examine patients remotely, which was clinically used during the COVID-19 pandemic, where we also investigated the usability for medical experts [154]. Other tactile telepresence systems we developed cover unmanned aerial vehicles (UAVs) [80].

To supplement physical safety on a cognitive level, we investigated acceptance in human-robot interaction scenarios. For example, we investigated the role size and posture of articulated structures and humanoids have on human comfort and perceived safety [155, 156]. Furthermore, we analyzed the perceived safety to understand which accelerations and velocities are considered trustworthy in human-robot collaboration scenarios [157, 158]. In this context, proposing the embedded ethics approach for the development of AI, VR robotics, and digital twins has been an important milestone [159]. I believe such approaches will help us to build trustworthy AI technologies designed for reality and to improve our quality of life.
