k-Robust Conflict-Based Search with Continuous time for Multi-robot Coordination

IROS 2024poster

Coordinating multiple robots is crucial for various real-life applications. Many Multi-Agent Path Finding (MAPF) algorithms have been proven to be successful in addressing this challenge. Nevertheless, some problems, such as unexpected delays during navigation, commonly arise when handling highlevel…

Exploration of 3D terrains using potential fields with elevation-based local distortions

ICRA 2020poster

Mobile robots can be used in numerous outdoor tasks such as patrolling, delivery and military applications. In order to deploy mobile robots in this kind of environment, where there are different challenges like slopes, elevations, or even holes, they should be able to detect such challenges and det…

Global Localization Over 2D Floor Plans with Free-Space Density Based on Depth Information

IROS 2020poster

Many applications with mobile robots require self-localization in indoor maps. While such maps can be previously generated by SLAM strategies, there are various localization approaches that use 2D floor plans as reference input. In this paper, we present a localization strategy using floor plan as m…

Long-term place recognition using multi-level words of spatial densities

IROS 2016poster

Proper place recognition on an environment that can change over time is fundamental for long-term SLAM. In such scenarios the observations obtained in the same region can drastically differ due to changes caused by semi-static objects, such as doors, furniture, etc. In this work, we extend a strateg…

Fast Monte Carlo Localization using spatial density information

ICRA 2015poster

Estimating the robot localization is a fundamental requirement for applications in robotics. For many years, Monte Carlo Localization (MCL) has been one of the most popular approaches to solve the global localization when using range finders, like sonars or lasers. It generally weights the estimates…

Ouroboros: Using potential field in unexplored regions to close loops

ICRA 2015poster

An autonomous robot requires a map of the environment for many tasks. Yet, in many cases, this map is unavailable and the robot must build one in real-time, in the so-called integrated exploration task. Several integrated exploration approaches adopt some sort of loop-closing strategy combined with…

Using n-grams of spatial densities to construct maps

IROS 2015poster

Place recognition is the frond-end of Simultaneous Localization and Mapping (SLAM). Topological representations depend on good association of vertices, which ultimately depends on the front-end. In this paper, we consider a robot lost in an unknown environment trying to construct a topological map t…
