Latent Safety Filters: When a Lossy Encoder Admits a Transferable Certificate
Johannes Mootz, Zahra Nili Ahmadabadi, Reza Akhavian
Latent safety filters certify safety on a learned low-dimensional representation of the state, enabling constraints that resist analytic description. Because the encoder is lossy,…
Control Barrier Functions with Audio Risk Awareness for Robot Safe Navigation on Construction Sites
Johannes Mootz, Reza Akhavian
Construction automation increasingly requires autonomous mobile robots, yet robust autonomy remains challenging on construction sites. These environments are dynamic and often visu…
Building Information Models to Robot-Ready Site Digital Twins (BIM2RDT): An Agentic AI Safety-First Framework
Reza Akhavian, Mani Amani, Johannes Mootz +2
The adoption of cyber-physical systems and jobsite intelligence that connects design models, real-time site sensing, and autonomous field operations can dramatically enhance digita…
Advancing Accessible Hand-Arm Vibration Safety Monitoring: ISO-Compliance with Wearable Sensors and Transfer Functions
Johannes Mootz, Reza Akhavian
Field workers are frequently exposed to hazardous vibrations, increasing the risk of Hand-Arm Vibration Syndrome (HAVS) and other long-term health problems. ISO 5349-1 provides gui…
