Non-Parametric Calibration of the Inverse Kinematic Matrix of a Three-Wheeled Omnidirectional Mobile Robot Based on Genetic Algorithms, Applied Sciences 2023, 13(2), 1053.

The application of this non-parametric calibration procedure has provided an average improvement of 82 % in the odometric estimation of the final position and orientation of the mobile robot.

Instant NeRF
Is a (spectacular) neural rendering model that learns a high-resolution 3D scene in seconds and can render images of that scene in a few milliseconds (YouTube demo).
The model was developed using the NVIDIA CUDA Toolkit and the Tiny CUDA Neural Networks library. Since it’s a lightweight neural network, it can be trained and run on a single NVIDIA GPU, running fastest on cards with NVIDIA Tensor Cores.

Optimal PID Control of a Brushed DC Motor with an Embedded Low-Cost Magnetic Quadrature Encoder for Improved Step Overshoot and Undershoot Responses in a Mobile Robot Application, Sensors 2022, 22(20), 7817.

This paper describes the optimization of the PID control of a brushed DC motor (BDCM) with an embedded low-cost magnetic quadrature encoder. This paper demonstrates empirically that the feedback provided by low-cost magnetic encoders produces some inaccuracies and control artifacts that are not usually considered in simulations, proposing a practical optimization approach in order to improve the step overshoot and undershoot controller response.

Application of a Single-Type eNose to Discriminate the Brewed Aroma of One Caffeinated and Decaffeinated Encapsulated Espresso Coffee Type, Chemosensors 2022, 10(10), 421.

This paper assesses a prototype single-type electronic nose (eNose) applied to differentiate the complex aromas generated by the caffeinated and decaffeinated versions of one encapsulated espresso coffee mixture type. The eNose has been developped by the laboratory and is composed of 16 single-type (identical) metal–oxide semiconductor (MOX) gas sensors based on microelectromechanical system (MEMS).

Article del diari EL PUNT AVUI: Els robots entren als hospitals

L'article descriu una prova pilot que s'està fent amb el robot Rose, que es una adaptació Neerlandesa del prototipus de robot TIAGo fabricat per l'empresa Pal-Robotics (ubicada a Barcelona).
El robot entra a les habitacions per comprovar que tothom és al llit i dorm sense problemes.
Segons s'indica a l'article, el robot utilitza una càmera infraroja per revisar l'habitació i avisar en cas de que la porta estigui tancada, si el pacient es troba caigut al terra o si la barana del llit està abaixada.

Sharing our Matlab function: matrix2WordEq.m

This function helps to copy a matlab matrix into a Word equation (trhough clipboard).
1) Create an empty equation in word. 2) Call this function. 3) Click over the Word equation. 4) Wait until the whole matrix has been copied (do not change the focus from Word).

The Assistant Personal Robot Project: From the APR-01 to the APR-02 Mobile Robot Prototypes, Designs 2022, 6(4), 66.

This paper describes the evolution of the Assistant Personal Robot (APR) project developed at the Robotics Laboratory of the University of Lleida, Spain. This paper describes the first APR-01 prototype design developed in this project and the basic hardware and anthropomorphic improvements proposed to maximize the perceived affinity with the new evolved APR-02 mobile robot prototype design.

Classification of Three Volatiles Using a Single-Type eNose with Detailed Class-Map Visualization, Sensors 2022, 22(14), 5262.
Paper published in the Special Issue: Electronic Gas Sensors, Sensor Arrays, and Electronic Noses for Indoor and Outdoor Environment Monitoring

The paper assesses the multivariate classification performance of a custom, low-cost eNose composed of 16 single-type (identical) MOX gas sensors for the classification of three volatiles. The paper proposes improving the visual interpretation of the classification results by means of generating a detailed 2D class-map representation based on the inverse of the orthogonal linear transformation obtained from a PCA and LDA analysis.

Enhancing the Sense of Attention from an Assistance Mobile Robot by Improving Eye-Gaze Contact from Its Iconic Face Displayed on a Flat Screen, Sensors 2022, 22(11), 4282.
Paper published in the Special Issue: Practical Application of Sensors and Signal Processing Techniques in Mobile Robots

This paper presents the enhancement of the sense of attention from the face of a human-sized mobile robot during an interaction. The perception of eye-gaze contact has been improved by manually calibrating the gaze of the robot relative to the location of the face of the person interacting with the robot. The sense of attention has been further enhanced by implementing cyclic face explorations with saccades in the gaze and by performing blinking and small movements of the mouth.
