MAPS Lab focuses on the frontier research in Cyber-physical Systems (e.g., mobile robots and mixed reality devices) with the goal to drastically improve their Reliability, Intelligence and Security in the wild. These works are motivated by the urgent need of robust localization and spatial perception solutions for mobile robotics and wearables to deal with i. sensing degradation (e.g., bad weather & poor illumination), ii. resource constraints (e.g., payloads, compute & energy budgets) and iii. malicious faults (e.g., adversarial attacks). Representative lines of research we have been recently focusing on are 4D Automotive Radar-enabled Mobile Autonomy and Sense Augmentation for First Responders.
