The public debt as handicap to economic growth

The impact that public debt has on economic growth is increasingly a topic of interest and it has been since the most recent economic and financial crisis of 2008 that it has come to occupy a prominent place in the literature. In this context, it becomes extremely important to understand the impact that the increase in public debt has on the growth of economies. Thus, the purpose of this research paper is to as...

BACA: um arquivo vivo para a conservação da biodiversidade microbiana dos Açores

BACA é o acrónimo do Banco de Algas e Cianobactérias dos Açores, uma coleção de culturas fundada em 2018 na Universidade dos Açores e associada ao Centro de Investigação em Biodiversidade e Recursos Genéticos, Polo Açores, da Universidade dos Açores (CIBIO-Açores). Esta coleção compreende mais de 800 culturas de microrganismos fotossintéticos (Figura 1), nomeadamente microalgas e cianobactérias, oriundas de tod...

Enhanced teleoperation interfaces for multi-second latency conditions: System d...

Adding human cognitive skills to planetary exploration through remote teleoperation can lead to more effective and valuable scientific data acquisition. Still, even small amounts of latency can significantly affect real-time operations, often leading to compromised robot safety, goal overshoot, and high levels of human mental fatigue and cognitive workload. Thus, novel operational strategies are necessary to co...

Feeling the slope?: Teleoperation of a mobile robot using a 7DOF haptic device ...

A well-known challenge in rover teleoperation is the operator’s lack of situational awareness (SA). This often leads to an inaccurate perception of the rover’s status and surroundings and, consequently, to faulty decision-making by the operator. We present a novel teleoperation interface to control the locomotion of a ground rover with a 7DOF force feedback device (sigma.7), while providing haptic feedback to e...

Cyanobacteria phylogenetic studies reveal evidence for polyphyletic genera from...

Cyanobacteria are among the most diverse morphological microorganisms that inhabit a great variety of habitats. Their presence in the Azores, a volcanic archipelago of nine islands in the middle of the North Atlantic Ocean, has already been reported. However, due to the high diversity of cyanobacteria habitats, their biodiversity is still understudied, mainly in extreme environments. To address this, a total of...

Long term experience in Autonomous Stations and production quality control

On the use of haptic tablets for UGV teleoperation in unstructured environments...

Teleoperation of Unmanned Ground Vehicles (UGVs), particularly for inspection of unstructured and unfamiliar environments still raises important challenges from the point of view of the operator interface. One of these challenges is caused by the fact that all information available to the operator is presented to the operator through a computer interface, providing only a partial view of the robot situation. Th...

Long term experience in autonomous stations and production quality control

Traction awareness through haptic feedback for the teleoperation of UGVs*

Teleoperation of Unmanned Ground Vehicles (UGVs) is dependent on several factors as the human operator is physically detached from the UGV. This paper focuses on situations where a UGV designed for search and rescue loses traction, thus becoming unable to comply with the operator's commands. In such situations, the lack of Situation Awareness (SA) may lead to an incorrect and inefficient response to the current...
