Beyond a Shadow of a Doubt: Close Proximity Geometry Reconstruction Using FMCW Radar Shadow Effects
Felix de Trogoff du Boisguezennec, Benjamin Ramtoula, Daniele De Martini
Reliable perception in adverse conditions remains challenging for autonomous systems, as cameras and LiDAR degrade in poor lighting or weather. Millimetre-wave FMCW radar is robust…
Multi-Robot Planning and Control from CCTV Camera Networks in a Real Warehouse
Luke Robinson, Benjamin Ramtoula, Anas Izaaryene +2
Off-board control of mobile robots from cameras embedded in the environment offers a practical path to scalable autonomy, moving sensing and compute off the robots. We extend this…
3D Foundation Model-Based Loop Closing for Decentralized Collaborative SLAM
Pierre-Yves Lajoie, Benjamin Ramtoula, Daniele De Martini +1
Decentralized Collaborative Simultaneous Localization And Mapping (C-SLAM) techniques often struggle to identify map overlaps due to significant viewpoint variations among robots.…
NeBula: Quest for Robotic Autonomy in Challenging Environments; TEAM CoSTAR at the DARPA Subterranean Challenge
Ali Agha, Kyohei Otsu, Benjamin Morrell +69
This paper presents and discusses algorithms, hardware, and software architecture developed by the TEAM CoSTAR (Collaborative SubTerranean Autonomous Robots), competing in the DARP…
MSL-RAPTOR: A 6DoF Relative Pose Tracker for Onboard Robotic Perception
Benjamin Ramtoula, Adam Caccavale, Giovanni Beltrame +1
Determining the relative position and orientation of objects in an environment is a fundamental building block for a wide range of robotics applications. To accomplish this task ef…
CAPRICORN: Communication Aware Place Recognition using Interpretable Constellations of Objects in Robot Networks
Benjamin Ramtoula, Ricardo de Azambuja, Giovanni Beltrame
Using multiple robots for exploring and mapping environments can provide improved robustness and performance, but it can be difficult to implement. In particular, limited communica…
