Navigation and docking maneuvers control of an autonomous omnidirectional platf...
Correia, João; Louro, Luís; Monteiro, Sérgio; Erlhagen, Wolfram; Bicho, EstelaThis paper presents a method to control and generate motion for omnidirectional mobile manipulators that operate in internal logistics scenarios. It proposes transport and maneuvering operations where human operators may coexist. Thus, to ensure that human operators can easily infer the vehicle's movements, the vehicle preferentially performs non-holonomic (i.e., like a differential drive vehicle), and only tak...
On the development of an ergonomic approach for the design of an industrial rob...
Colim, Ana S.; Cardoso, André; Bicho, Estela; Louro, Luís; Alves, Carla; Ribeiro, Pedro; Pereira, Débora; Monteiro, Sérgio; Costa, NélsonAs industries push for continuous technological innovation to boost their competitiveness, the need to balance techno-economical goals with emerging societal needs is now more pressing than ever. Inspired by the novel paradigm of Industry 5.0, we aim to place human physical and cognitive needs at the center of the production process, introducing proactive and human-aware robots capable of collaboration as co-wo...
A data recording mobile application to create datasets of vehicle users’ routines
Guimarães, Pedro; Ferreira, Flora; Silva, Ana Carolina; Erlhagen, Wolfram; Monteiro, Sérgio; Bicho, EstelaOne of today's automotive research focus is the development of vehicles for the future, with their own intelligence, aware of their occupants, able to give support to its users, striving for natural and efficient interaction, and giving rise to the concept of the cognitive vehicle. Furthermore, truly adaptive intelligence can be achieved with assistance systems capable of adapting to different drivers. Vehicles...
Endowing intelligent vehicles with the ability to learn user’s habits and prefe...
Barbosa, Paulo; Ferreira, Flora; Fernandes, Carlos; Erlhagen, Wolfram; Guimarães, Pedro; Wojtak, Weronika; Monteiro, Sérgio; Bicho, EstelaA private vehicle frequently carries the same passengers who routinely take specific objects with them, have their vehicle comfort preferences, and visit the same places at relatively the same time of a given day or day of the week. Thus, developing intelligent vehicles that are able to reduce the cognitive workload of the drivers by learning and adapting to their occupants’ routines is of the highest interest....
Trajectory tracking for the inspection of deformable objects considering manipu...
Borges, Carlos Alberto Peixoto; Ribeiro, José Miguel Maia; Louro, Luis; Vicente, Paulo Sérgio Cunha; Faria, Carlos; Monteiro, Sérgio; Bicho, EstelaThis work deals with the manipulation of deformable objects for defect inspection purposes. The required inspection movements, obtained from mimicking demonstrated trajectories, are realized with a 7-DoF serial arm and a fixed grasp support. These trajectories can be realized in different zones, as such, we use this freedom, with the various possibilities for the inverse kinematics problem and the elbow redunda...
Dietary intake of young Portuguese handball players
de Sá, Carla; Monteiro, Sérgio; Osório, Sofia; Barbosa, Tiago; Sá, PauloThe aim of this study was to analyse dietary intake (macronutrients and micronutrients) in young female and male handball athletes. A transversal study was performed with young handball players from sub 16 and 18 Portuguese Handball Federation, who volunteered to participate in this study. Anthropometric (weight and height measure), nutritional intake (using food frequency questionnaire) and position in the gam...

Vitrectomized versus non-vitrectomized eyes in diabetic macular edema response ...
Pessoa, Bernardete; Leite, João; Heitor, João; Coelho, João; Monteiro, Sérgio; Coelho, Constança; Figueira, João; Meireles, AngelinaTo evaluate the role of the vitreous in the management of diabetic macular edema with ranibizumab intravitreal injections in a pro re nata regimen. Prospective study of 50 consecutive eyes with diabetic macular edema treated with ranibizumab and 12 months of follow-up. Primary endpoint: to assess differences between non-vitrectomized and vitrectomized eyes in the number injections needed to control the edema. S...
From handcrafting to a certified and ergonomic collaborative workstation: the d...
Cunha, Joao G.; Faria, Carlos; Colim, Ana; Oliveira, Joao; Rocha, Luis A.; Silva, Marcio; Monteiro, Sérgio; Bicho, EstelaAs manufacturing enters an era of mass customization, new technological solutions with more versatility and flexibility are brought to the industry. Collaborative robots, or COBOTs, can now safely work near humans, a key advantage that enables highly-flexible production and opens the possibility to tackle the incidence of occupational health problems. Although the advantages of collaborative robotic manufacturi...
Towards endowing intelligent cars with the ability to learn the routines of mul...
Wojtak, Weronika; Ferreira, Flora José Rocha; Guimarães, Pedro; Barbosa, Paulo; Monteiro, Sérgio; Erlhagen, Wolfram; Bicho, EstelaDriving a car is often a routine activity that includes visiting the same locations at about the same time on a certain day of the week. Here, we present a learning system based on Dynamic Neural Fields that allows an intelligent vehicle to acquire sequential and temporal information about daily driving routines. Learning is fast, implicit (no need to specify destinations in advance), continuous, and can be ada...
