AirSwarm: Enabling Cost-Effective Multi-UAV Research with COTS drones

IROS 2025

Traditional unmanned aerial vehicle (UAV) swarm missions rely heavily on expensive custom-made drones with onboard perception or external positioning systems, limiting their widespread adoption in research and education. To address this issue, we propose AirSwarm. AirSwarm democratizes multi-drone c

Autonomous 3D Moving Target Encirclement and Interception with Range Measurement

IROS 2025

Commercial UAVs are an emerging security threat as they are capable of carrying hazardous payloads or disrupting air traffic. To counter UAVs, we introduce an autonomous 3D target encirclement and interception strategy. Unlike traditional ground-guided systems, this strategy employs autonomous drone

Non-cooperative Stochastic Target Encirclement by Anti-synchronization Control via Range-only Measurement

ICRA 2023poster

This paper investigates the stochastic moving target encirclement problem in a realistic setting. In contrast to typical assumptions in related works, the target in our work is non-cooperative and capable of escaping the circle containment by boosting its speed to maximum for a short duration. In ex…
