Optimal Potential Shaping on SE(3) via Neural ODEs on Lie Groups

no code implementations25 Jan 2024 Yannik P. Wotte, Federico Califano, Stefano Stramigioli

The optimal control problem is phrased as an optimization of a neural ODE on the Lie group SE(3), and the controller is iteratively optimized.

On the use of energy tanks for robotic systems

no code implementations30 Nov 2022 Federico Califano, Ramy Rashad, Cristian Secchi, Stefano Stramigioli

In this document we describe and discuss energy tanks, a control algorithm which has gained popularity inside the robotics and control community over the last years.

Port-Hamiltonian Modeling of Ideal Fluid Flow: Part II. Compressible and Incompressible Flow

no code implementations3 Dec 2020 Ramy Rashad, Federico Califano, Frederic P. Schuller, Stefano Stramigioli

Starting from the group of diffeomorphisms as a configuration space for the fluid, the Stokes Dirac structure is derived by Poisson reduction and then augmented by boundary ports and distributed ports.

Port-Hamiltonian Modeling of Ideal Fluid Flow: Part I. Foundations and Kinetic Energy

no code implementations3 Dec 2020 Ramy Rashad, Federico Califano, Frederic P. Schuller, Stefano Stramigioli

In this two-parts paper, we present a systematic procedure to extend the known Hamiltonian model of ideal inviscid fluid flow on Riemannian manifolds in terms of Lie-Poisson structures to a port-Hamiltonian model in terms of Stokes-Dirac structures.

On Reward Shaping for Mobile Robot Navigation: A Reinforcement Learning and SLAM Based Approach

no code implementations10 Feb 2020 Nicolò Botteghi, Beril Sirmacek, Khaled A. A. Mustafa, Mannes Poel, Stefano Stramigioli

We present a map-less path planning algorithm based on Deep Reinforcement Learning (DRL) for mobile robots navigating in unknown environment that only relies on 40-dimensional raw laser data and odometry information.
