Chalito: An Extensible Library for Filtering-Based State Estimation in Quadruped Robots
Hilton Marques Souza Santana, João Carlos Virgolino Soares, Marco Antonio Meggiolaro +1
State estimation is essential for quadruped robots, enabling robust locomotion, navigation, and control. While many estimators have been proposed in the literature, existing implem…
Iterated Invariant EKF for Quadruped Robot Odometry
Hilton Marques Souza Santana, João Carlos Virgolino Soares, Sven Goffin +4
Kalman filter-based algorithms are fundamental for mobile robots, as they provide a computationally efficient solution to the challenging problem of state estimation. However, they…
BinWalker: Development and Field Evaluation of a Quadruped Manipulator Platform for Sustainable Litter Collection
Giulio Turrisi, Angelo Bratta, Giovanni Minelli +4
Litter pollution represents a growing environmental problem affecting natural and urban ecosystems worldwide. Waste discarded in public spaces often accumulates in areas that are d…
Towards Proprioceptive Terrain Mapping with Quadruped Robots for Exploration in Planetary Permanently Shadowed Regions
Alberto Sanchez-Delgado, João Carlos Virgolino Soares, Victor Barasuol +1
Permanently Shadowed Regions (PSRs) near the lunar poles are of interest for future exploration due to their potential to contain water ice and preserve geological records. Their c…
Online Object-Level Semantic Mapping for Quadrupeds in Real-World Environments
Emad Razavi, Angelo Bratta, João Carlos Virgolino Soares +2
We present an online semantic object mapping system for a quadruped robot operating in real indoor environments, turning sensor detections into named objects in a global map. Durin…
Towards An Adaptive Locomotion Strategy For Quadruped Rovers: Quantifying When To Slide Or Walk On Planetary Slopes
Alberto Sanchez-Delgado, João Carlos Virgolino Soares, David Omar Al Tawil +5
Legged rovers provide enhanced mobility compared to wheeled platforms, enabling navigation on steep and irregular planetary terrains. However, traditional legged locomotion might b…
