Cold-start and data sparsity problems in a digital twin based recommendation sy...

The emergence of Digital Twins (DT) in Industry 4.0 has enabled the decision support systems taking advantage of more effective recommendation systems (RS). Despite the RS’s growing popularity and ability to support decision-makers, these face two significant challenges, cold-start and data sparsity, which limits the system’s capability to provide effective and accurate decision support. This paper aims to addr...

Benchmarking Edge Computing Devices for Grape Bunches and Trunks Detection usin...

Purpose: Visual perception enables robots to perceive the environment. Visual data is processed using computer vision algorithms that are usually time-expensive and require powerful devices to process the visual data in real-time, which is unfeasible for open-field robots with limited energy. This work benchmarks the performance of different heterogeneous platforms for object detection in real-time. This resear...

DC motor educational kit: a teaching aid in control theory

This paper describes a laboratory control theory experiment supported by the use of a DC Motor Educational Kit. The impact, as a teaching aid, of the proposed laboratory control experiment is evaluated, having in mind the student’s feedback. The DC motor that is used in the developed educational Kit is the EMG30, being a low cost 12 V motor equipped with encoders and a 30:1 reduction gearbox. The experiment is ...

Multimodal interaction and serious game for assistive robotic devices in a simu...

Sports and physical activities allow people with disabilities to have better quality of life. The proposed work aimed to develop a multimodal interaction platform of robotic devices in a simulated environment for users to train different interface options. The suggested scenarios allow a user to interact with an Intelligent Wheelchair (IW) and with an Intelligent Robotic Ramp (IRR) performing different tasks in...

Special Issue Robótica 2014

Intelligent wheelchair driving: bridging the gap between virtual and real intel...

Wheelchairs are important locomotion devices for handicapped and senior people. With the increase in the number of senior citizens and the increment of people bearing physical deficiencies, there is a growing demand for safer and more comfortable wheelchairs. So the new Intelligent Wheelchair (IW) concept was introduced. Like many other robotic systems, the main capabilities of an intelligent wheelchair should ...
