Exploration with Global Consistency Using Real-Time Re-integration and Active Loop Closure
Yichen Zhang, Boyu Zhou, Luqi Wang +1
Despite recent progress of robotic exploration, most methods assume that drift-free localization is available, which is problematic in reality and causes severe distortion of the r…
Neither Fast Nor Slow: How to Fly Through Narrow Tunnels
Luqi Wang, Hao Xu, Yichen Zhang +1
Nowadays, multirotors are playing important roles in abundant types of missions. During these missions, entering confined and narrow tunnels that are barely accessible to humans is…
FUEL: Fast UAV Exploration using Incremental Frontier Structure and Hierarchical Planning
Boyu Zhou, Yichen Zhang, Xinyi Chen +1
Autonomous exploration is a fundamental problem for various applications of unmanned aerial vehicles. Existing methods, however, were demonstrated to insufficient exploration rate,…
Decentralized Visual-Inertial-UWB Fusion for Relative State Estimation of Aerial Swarm
Hao Xu, Luqi Wang, Yichen Zhang +2
The collaboration of unmanned aerial vehicles (UAVs) has become a popular research topic for its practicability in multiple scenarios. The collaboration of multiple UAVs, which is…
