Hierarchical Aggregation of Semantic Uncertainty in 3D Scene Graphs
Carlos Cueto Zumaya, Iacopo Catalano, Wallace Moreira Bessa +1
Open-vocabulary 3D Scene Graphs (3DSGs) ground each object node in a vision-language embedding, yet they record every entry as equally certain, so a robot querying the map cannot t…
Sliding Mode Control of Cardiac Rhythms in the Sinoatrial Node using Gaussian Process Regression
Gabriel da Silva Lima, Marcelo Amorim Savi, Wallace Moreira Bessa
The Sinoatrial node (SA), also called natural pacemaker, is responsible to initiate the heart electrical activity, usually represented by electrocardiograms (ECGs). Abnormalities a…
Intelligent Control for Path-Following of an Unmanned Mass-Centric Surface Vehicle
Gabriel da Silva Lima, Tomi Westerlund, Wallace Moreira Bessa
Addressing the control and maneuverability of surface vehicles with dynamically changing mass distributions is still an open problem. To solve the problem, we propose an intelligen…
Influence of Radial Basis Activation Functions on Intelligent Controller for Robotic Manipulators
Kimmo Paldanius, Gabriel Da Silva Lima, Wallace Moreira Bessa
This paper presents an intelligent control framework for trajectory tracking of robotic manipulators using radial basis function (RBF) neural networks for online disturbance estima…
Learning-based control of a single-DOF Aero system
Gabriel da Silva Lima, Wallace Moreira Bessa
This paper presents a learning-based control framework that integrates feedback linearization with reinforcement learning for the adaptive control of nonlinear mechatronic systems.…
Machine Learning-based Feedback Linearization Control of Quadrotor Subject to Unmodeled Dynamics
Amos Alwala, Gabriel da Silva Lima, Wallace Moreira Bessa
The control of agile quadrotors in dynamic and uncertain environments remains an open area of investigation to this day, particularly when the complete system dynamics are partiall…
Occupancy-Grounded Room Segmentation for Hierarchical 3D Scene Graphs
Carlos Cueto Zumaya, Iacopo Catalano, Jorge Peña-Queralta +1
Hierarchical 3D scene graphs (3DSGs) for indoor robots organize geometric and semantic information across spatial scales, with a room layer that connects object-level perception to…
Intelligent Control of Differential Drive Robots Subject to Unmodeled Dynamics with EKF-based State Estimation
Amos Alwala, Yuchen Hu, Gabriel da Silva Lima +1
Reliable control and state estimation of differential drive robots (DDR) operating in dynamic and uncertain environments remains a challenge, particularly when system dynamics are…
