Adaptive Risk-Based Replanning For Human-Aware Multi-Robot Task Allocation With Local Perception

In this letter, we propose an adaptive risk-based replanning strategy in the context of multirobot task allocation for dealing with limitations of local perception and unpredicted human behavior. Our replanning method is based on the variations of social r ...

Multi-Robot Coordination in Dynamic Environments Shared with Humans

Alcherio Martinoli, Zeynab Talebpour

This work addresses multi-robot coordination in social human-populated environments based on a Hoplites-based framework for solving the multi-robot task allocation problem. Humans are considered in the proposed coordination mechanism by means of accounting ...

Risk-Based Human-Aware Multi-Robot Coordination in Dynamic Environments Shared with Humans

Alcherio Martinoli, Zeynab Talebpour

In this paper, we propose a risk-based coordination method for the Multi-Robot Task Allocation (MRTA) problem in human-populated environments. We introduce risk-based bids that incorporate human trajectory prediction uncertainties and furthermore, social c ...

Market-based Coordination in Dynamic Environments Based on Hoplites Framework

Alcherio Martinoli, Zeynab Talebpour, Stefano Savarè

This work focuses on multi-robot coordination based on the Hoplites framework for solving the multi-robot task allocation (MRTA) problem. Three variations of increasing complexity for the MRTA problem, spatial task allocation based on distance, spatial tas ...

Optimal Path Planning and Coverage Control for Multi-Robot Persistent Coverage in Environments with Obstacles

Alcherio Martinoli, Zeynab Talebpour, José Manuel Palacios Gasos

Persistent coverage aims to maintain a certain coverage level over time in an environment where such level deteriorates. This level can be associated to temperature, dust or sensor information. We propose an algorithmic solution in which each robot locally ...

Incorporating Perception Uncertainty in Human-Aware Navigation: A Comparative Study

Alcherio Martinoli, Zeynab Talebpour, Rodrigo Martins de Matos Ventura

In this work, we present a novel approach to human-aware navigation by probabilistically modelling the uncertainty of perception for a social robotic system and investigating its effect on the overall social navigation performance. The model of the social ...

A Comparison of PSO and Reinforcement Learning for Multi-Robot Obstacle Avoidance

Alcherio Martinoli, Zeynab Talebpour, Ezequiel Leonardo Di Mario

The design of high-performing robotic controllers constitutes an example of expensive optimization in uncertain environments due to the often large parameter space and noisy performance metrics. There are several evaluative techniques that can be employed ...
