This work presents a novel approach for the online supervision of robotic systems assembled from multiple complex components with skillset-based architectures, using Petri nets (PN). Predictive runtime verification is performed, which warns the system user about actions that would lead to the violat…
In this paper, we propose a formal language to specify robot skills, i.e. the elementary behaviours or functions provided by the robot platform in order to perform an autonomous mission. The advantage of the language we propose is that it integrates a wide range of elements that allows to define and…
Fault-tolerant architectures are mandatory to ensure the robustness of autonomous robots performing missions in complex and uncertain environments. The first step of a fault-tolerant mechanism is the detection of a faulty behavior of the system. It is then important to provide tools to help robot de…
Providing guarantees on the system behavior is mandatory in order to let the robots enter our every-day life. Among these guarantees, proving the fulfillment of real-time constraints on the software is a key issue, as their violation could result into unexpected and unsafe behaviors. In this paper,…
