A safe autonomous stacker in human shared workspaces
Louro, Luís; Teixeira, Duarte; Malheiro, Tiago Emanuel Quintas; Mesquita, Luís; Machado, Toni; Monteiro, Sérgio; Erlhagen, Wolfram; Bicho, EstelaThis paper proposes a solution for safe navigation of stacker vehicles in workspaces shared with people, with a focus on the docking manoeuvres for pallet picking and dropping. Behaviours for way-point and wall following are developed following the attractor dynamics approach. Then, these behaviours are orchestrated by state machines (that activate or deactivate them) depending on the specific task. Each of the...
A software framework for the implementation of dynamic neural field control arc...
Malheiro, Tiago Emanuel Quintas; Bicho, Estela; Machado, Toni; Louro, Luís; Monteiro, Sérgio; Vicente, Paulo; Erlhagen, WolframUseful and efficient human-robot interaction in joint tasks requires the design of a cognitive control architecture that endows robots with crucial cognitive and social capabilities such as intention recognition and complementary action selection. Herein, we present a software framework that eases the design and implementation of Dynamic Neural Field (DNF) cognitive architectures for human-robot joint tasks. We...
MUVTIME: a Multivariate time series visualizer for behavioral science
Sousa, Emanuel Augusto Freitas; Malheiro, Tiago Emanuel Quintas; Bicho, Estela; Erlhagen, Wolfram; Santos, Jorge A.; Pereira, Alfredo F.As behavioral science becomes progressively more data driven, the need is increasing for appropriate tools for visual exploration and analysis of large datasets, often formed by multivariate time series. This paper describes MUVTIME, a multimodal time series visualization tool, developed in Matlab that allows a user to load a time series collection (a multivariate time series dataset) and an associated video. T...
Transportation of long objects in unknown cluttered environments by a team of r...
Machado, Toni Daniel Neto; Malheiro, Tiago Emanuel Quintas; Monteiro, Sérgio; Bicho, Estela; Erlhagen, WolframWe present a distributed architecture for teams of two autonomous mobile robots that act in coordination in a joint transportation task of long objects. The team is able to perform its transportation task in unknown environments while avoiding static or moving obstacles. The working environment can be cluttered and with narrow passages such as corridors, corners and doors. These characteristics make our approac...
