Data Scaling for Navigation in Unknown Environments
Lauri Suomela, Naoki Takahata, Sasanka Kuruppu Arachchige +2
Generalization of imitation-learned navigation policies to environments unseen in training remains a major challenge. We address this by conducting the first large-scale study of h…
Synthetic vs. Real Training Data for Visual Navigation
Lauri Suomela, Sasanka Kuruppu Arachchige, German F. Torres +2
This paper investigates how the performance of visual navigation policies trained in simulation compares to policies trained with real-world data. Performance degradation of simula…
PlaceNav: Topological Navigation through Place Recognition
Lauri Suomela, Jussi Kalliola, Harry Edelman +1
Recent results suggest that splitting topological navigation into robot-independent and robot-specific components improves navigation performance by enabling the robot-independent…
Is Alice Really in Wonderland? UWB-Based Proof of Location for UAVs with Hyperledger Fabric Blockchain
Lei Fu, Paola Torrico Morón, Jorge Peña Queralta +3
Remote identification of Unmanned Aerial Vehicles (UAVs) is becoming increasingly important since more UAVs are being widely used for different needs in urban areas. For example, i…
Benchmarking Visual Localization for Autonomous Navigation
Lauri Suomela, Jussi Kalliola, Atakan Dag +2
This work introduces a simulator-based benchmark for visual localization in the autonomous navigation context. The dynamic benchmark enables investigation of how variables such as…
