  • Electro-pneumatic control of soft robotic hand prosthesis actuators
    Publication . D`Almeida, Hugo; Almeida, Paulo; Charters De Azevedo, Tiago; Gonçalves Cavaco Mendes, Mário José
    This project arises in response to some limitations of the current conventional prostheses, namely aesthetic, mechanical and cost, that fail to fulfil the needs of its users, for example with soft objects. The results obtained until now proved to be satisfactory in the approximation of the hand morphology, low cost and the designed mechanical properties. However, this paper aims to present a developed electro-pneumatic control board to control the soft robotic prosthesis of the human hand. The first tests done with this control board show that it will be necessary to improve the physical design and the 3D printing of the soft actuators (fingers) due to some leaks in the printed actuators.

  • Neuro-fuzzy techniques in FDI system for sugar factory actuators
    Publication . Mendes, Mário J. G. C.; Kowal, Marek; Korbicz, Józef; Costa, José M. G. Sá da
    Fault diagnosis systems have an important role in industrial plants because the early fault detection and isolation (FDI) can minimize damages in the plants. The main aim of this work is to propose a two-stage neuro-fuzzy approach as a fault diagnosis system in dynamic processes. The first stage of the system is responsible for fault detection and is implemented using a neuro-fuzzy model. The second stage of the system is responsible for fault isolation and is built using an hierarchical structure of fuzzy neural networks. The FDI system is applied to fault diagnosis in the sugar factory actuators.
