Learning to Identify Graphs from Node Trajectories in Multi-Robot Networks

no code implementations10 Jul 2023 Eduardo Sebastian, Thai Duong, Nikolay Atanasov, Eduardo Montijano, Carlos Sagues

The graph identification problem consists of discovering the interactions among nodes in a network given their state/feature trajectories.

Distributed outer approximation of the intersection of ellipsoids

no code implementations24 May 2023 Rodrigo Aldana-Lopez, Eduardo Sebastian, Rosario Aragues, Eduardo Montijano, Carlos Sagues

The outer Lowner-John method is widely used in sensor fusion applications to find the smallest ellipsoid that can approximate the intersection of a set of ellipsoids, described by positive definite covariance matrices modeling the quality of each sensor.

This paper presents LEMURS, an algorithm for learning scalable multi-robot control policies from cooperative task demonstrations.

Multi-robot Implicit Control of Massive Herds

no code implementations20 Sep 2022 Eduardo Sebastian, Eduardo Montijano, Carlos Sagues

The problem is very challenging due to the highly complex repulsive evaders' dynamics and the underdetermined states to control.

On the Stability of Electromechanical Switching Devices

no code implementations26 Jul 2022 Edgar Ramirez-Laboreo, Carlos Sagues, Eduardo Moya-Lasheras, Eloy Serrano-Seco

Electromagnetic relays and solenoid actuators are commonly used for their bistable behavior, which allows for switching between two states in electrical, pneumatic, or hydraulic circuits, among other applications.
