XAI Framework for Fall Detection in an AAL System
Messaoudi, Chaima; Kalbermatter, Rebeca B.; Lima, José; Pereira, Ana I.; Guessoum, Zahia; Kalbermatter, Rebeca B.The Ambient Assisted Living (AAL) systems are humancentered and designed to prioritize the needs of elderly individuals, providing them with assistance in case of emergencies or unexpected situations. These systems involve caregivers or selected individuals who can be alerted and provide the necessary help when needed. To ensure effective assistance, it is crucial for caregivers to understand the reasons behind...
Energy Efficiency Analysis of Differential and Omnidirectional Robotic Platform...
Chellal, Arezki Abderrahim; Braun, João; Junior, Luciano Bonzatto; Faria, Milena; Kalbermatter, Rebeca B.; Gonçalves, José; Costa, Paulo Gomes daAs robots have limited power sources. Energy optimization is essential to ensure an extension for their operating periods without needing to be recharged, thus maximizing their uptime and minimizing their running costs. This paper compares the energy consumption of different mobile robotic platforms, including differential, omnidirectional 3-wheel, omnidirectional 4-wheel, and Mecanum platforms. The comparison ...
Automatic Fall Detection with Thermal Camera
Kalbermatter, Rebeca B.; Franco, Tiago; Pereira, Ana I.; Valente, António; Soares, Salviano Pinto; Lima, JoséPeople are living longer, promoting new challenges in healthcare. Many older adults prefer to age in their own homes rather than in healthcare institutions. Portugal has seen a similar trend, and public and private home care solutions have been developed. However, age-related pathologies can affect an elderly person’s ability to perform daily tasks independently. Ambient Assisted Living (AAL) is a domain that u...
Design and Development of an Omnidirectional Mecanum Platform for the RobotAtFa...
Braun, João; Baidi, Kaïs; Bonzatto, Luciano; Berger, Guido; Pinto, Milena F.; Kalbermatter, Rebeca B.; Klein, Luan C.; Grilo, Vinicius F.S.B.Robotics competitions are highly strategic tools to engage and motivate students, cultivating their curiosity and enthusiasm for technology and robotics. These competitions encompass various disciplines, such as programming, electronics, control systems, and prototyping, often beginning with developing a mobile platform. This paper focuses on designing and implementing an omnidirectional mecanum platform, encom...
A ubiquitous learning approach on robotics
Mota, Fernanda P.; Kalbermatter, Rebeca B.; Oliveira, Lizandro de S.; Lima, JoséUbiquitous learning refers to the integration of learning processes with everyday environments and activities using technology. By leveraging ubiquitous learning principles in the field of robotics, we can foster an immersive and interactive learning environment that promotes continuous learning and knowledge acquisition. This paper presents an in-depth exploration of a ubiquitous learning approach for robotics...
Smart systems for buildings
Kalbermatter, Rebeca B.Life in society has initiated a search for comfort and security in social centers. This quest has generated revolutions within the knowledge about the technologies involved, making the environment automated and integrated. Along with this increase, ecological concerns have also arisen, which have been involved since the conception of intelligent structures, remaining throughout their use. Based on these two pil...
Smart systems for monitoring buildings - an IoT application
Kalbermatter, Rebeca B.; Brito, Thadeu; Braun, João; Pereira, Ana I.; Ferreira, Ângela P.; Valente, António; Lima, JoséLife in society has initiated a search for comfort and security in social centers. This search generated revolutions within the knowledge about the technologies involved, making the environments automated and integrated. Along with this increase, ecological concerns have also arisen, which have been involved since the design of intelligent buildings, remaining through the years of their use. Based on these two ...
A realistic simulation environment as a teaching aid in educational robotics
Lima, José; Kalbermatter, Rebeca B.; Braun, João; Brito, Thadeu; Berger, Guido; Costa, Paulo Gomes daThe experimental component is an essential method in Engineering education. Sometimes the availability of laboratories and components is compromised, and the COVID-19 pandemic worsened the situation. Resorting to an accurate simulation seems to help this process by allowing students to develop the work, program, test, and validate it. Moreover, it lowers the development time and cost of the prototyping stages o...
Monitoring system for smart buildings - apolo building case
Kalbermatter, Rebeca B.; Brito, Thadeu; Braun, João; Pereira, Ana I.; Lima, JoséThe demand for better safety and comfort conditions in social centers served as an incentive to improve the automation of buildings, making them intelligent systems that could be integrated. However, alongside these innovations, there has also arisen a concern for the ecological risks surrounding the smart building. With these factors as a basis, this work aimed to monitor three main systems within each apartme...
