RHINO-AR: An Augmented Reality Exhibit for Teaching Mobile Robotics Concepts in Museums
Researchers built an AR exhibit on Magic Leap 2 that visualizes LiDAR and path planning for museum visitors.
A research team from the University of Bonn has developed RHINO-AR, an interactive augmented reality exhibit designed to teach mobile robotics concepts in museums. The system, built for the Magic Leap 2 headset using the Unity engine, places a virtual reconstruction of the historic RHINO robot directly into the real exhibition space at the Deutsches Museum Bonn. It addresses a key limitation of their previous VR version by keeping visitors connected to the physical environment and the actual robot on display. The AR system uses real-time environment meshing and interactive visualizations to make complex, invisible robotics processes—like LiDAR sensing, terrain traversability analysis, and path planning algorithms—understandable to the general public.
In a two-day museum study involving 22 participants, the team evaluated the system's usability, technical performance, and educational impact. The results showed that RHINO-AR was well-received, effectively conveyed core navigation concepts, and was generally preferred over the team's earlier VR exhibit. Participants cited its stronger physical grounding and increased realism as key advantages. The project demonstrates a practical application of AR for STEM education, successfully bridging the gap between abstract robotic algorithms and tangible, engaging public learning experiences.
- Built on Magic Leap 2 using Unity to visualize LiDAR and path planning in real-time.
- Evaluated in a 2-day museum study with 22 participants, showing high satisfaction and educational effectiveness.
- Preferred over a previous VR version for its physical grounding and realism, closing the 'reality gap'.
