Poéticas e Políticas da Autorrepresentação na Fotografia Africana e Afrodescend...

O artigo analisa processos contemporâneos de descolonização do olhar e de autodeterminação visual na fotografia africana e afrodescendente em Portugal, entendendo a imagem como um campo de disputa em torno da representação, da memória e da cultura visual. A discussão proposta tem como base um fenômeno que ocorre atualmente em Portugal e em diversos locais do mundo: o impulso de emancipação do olhar desses sujei...

Advances in Shoulder Pain Imaging

Shoulder pain is among the most frequent musculoskeletal complaints and remains a significant therapeutic challenge in clinical practice. A wide spectrum of conditions may contribute to this symptom, including rotator cuff tendinosis or tears, calcific tendinopathy, labral or capsuloligamentous injuries and degenerative changes of the glenohumeral joint. Accurate diagnosis requires an integrated approach that c...

LAR@Home 2025 Team Description Paper

This paper describes the development and progresses of the team LAR@Home from the University of Minho, Portugal, for the RoboCup@Home competition that will take place in Salvador, Brazil, in 2025. After the robot’s participation in the 2023 and 2024 editions, the main efforts centred on improving and developing the localisation and navigation system, developing a GUI system that can be used in competitions visu...

Multibody model of the human-inspired robot CHARMIE

The rapid ageing of the worldwide population raises pressing concerns related to ensuring proper healthcare and quality of life for older adults. A human-like mobile domestic robot, named CHARMIE, is being produced to aid in these situations by performing household chores, thus increasing the autonomy of persons with mobility limitations. The present work provides a valuable contribution to the development of C...

Development of a multibody simulator to study the CHARMIE robot

[Excerpt] 1. INTRODUCTION The Laboratory of Automation and Robotics of the University of Minho has developed CHARMIE, a human-inspired robot designed to assist humans in domestic tasks [1] (See Figure 1). One of the challenges in developing a complex mobile manipulator robot is testing and optimizing its control. Damages to the physical prototype, or possible hazardous situations, can be avoided by testing cont...

Multibody dynamics in robotics with focus on contact events

Multibody dynamics methodologies have been fundamental tools utilized to model and simulate robotic systems that experience contact conditions with the surrounding environment, such as in the case of feet and ground interactions. In addressing such problems, it is of paramount importance to accurately and efficiently handle the large body displacement associated with locomotion of robots, as well as the dynamic...

LAR@Home 2024 Team Description Paper

This paper describes the development and progresses of the team LAR@Home from the University of Minho, Portugal, for the RoboCup@Home competition that will take place in Eindhoven, Netherlands, in 2024. After the robot’s first participation in the 2023 edition, the main efforts focus on improving the mechanical and electronic structure in order to highlight its anthropomorphic approach and addition of a new rob...

Dynamic modeling and simulation of the omnidirectional locomotion of a mobile m...

Omnidirectional wheeled locomotion is often utilized by robots intended to work in indoor environments due to its high manoeuvrability in confined spaces. CHARMIE, a human-inspired mobile manipulator that aims to assist patients with mobility limitations, employs four Swedish wheels supported by an independent suspension to navigate through domestic environments. Multibody dynamics is one of the main tools whic...

Comparative study on burnout among higher education professors in Portugal and ...

The global pandemic context experienced in recent years has exacerbated the reality that the work environment does not always offer the necessary conditions for task completion. For example, in Higher Education Institutions (HEIs), all over the world, were closing, to safeguard the health of professors, students, and education professionals had to change teaching methods, namely, remote teaching, involving new ...
