- Chain of Trust: Integrating IoT and Blockchain to Certify Wild Mushroom Growth QualityPublication . Rosse, Higor Vendramini; Camargo, Caio; Gonçalves, Estefânia; Sabiri, Khadija; Coelho, João PauloThis paper presents the preliminary results of the study developed within the scope of the ”Safe2Taste” project presenting the main concept of hardware and software architectures. The project aims to build a monitoring system supported by IoT technologies and covered by a security layer through interaction with a blockchain network to be applied in an edible mushroom production system. The hardware and software components were validated in the laboratory and taken to domestic production for the concept phase. the impacts caused by the inconsistent production management are in the analysis phase as the data collection is not finalized. At this stage, the implementation of low-cost IoT nodes is intended for collecting and monitoring parameters, these parameters are sent via the MQTT protocol to the cloud, starting the blockchain mining process and storing the mining result in an immutable database. The information from monitoring, as well as the keys generated in blockchain mining, will be presented in an intuitive way through a user interface built using the NODE-red framework.
- Educational robotics summer camp at IPBPublication . Gonçalves, José; Lima, José; Brito, Thadeu; Brancalião, Laiany Suganuma; Camargo, Caio; Oliveira, Vitor; Conde, Miguel ÁngelRobotics in education has special relevance in current digital society where students should know how to deal with technology. In this paper, it is presented an educational experiment in the mobile robotics domain. The referred experiment was part of a summer camp, which took place at the Polytechnic Institute of Bragança Portugal, being its technological aspects related with mobile robotics. Other than the technological aspects, the students participated in many different cultural and social activities, having the opportunity to know the city of Bragança and also to know different persons, mainly students, professors, researchers and laboratory technicians. The applied approach in the summer camp was a challenge based learning methodology, being involved in the experiment 3 professors, 4 monitors, working with a group of 16 secondary school students. The described experiment was planned as an activity of the RoboSTEAM - Integrating STEAM and Computational Thinking development by using robotics and physical devices ERASMUS+ Project.
- Emídio Garcia school pilot description: a robosteam Erasmus+ project activity based on a challenge based learning approachPublication . Camargo, Caio; Brancalião, Laiany Suganuma; Gonçalves, José; Lima, José; Ramos, Maria; Fernandes, Luisa; Trovisco, Manuel; Conde, Miguel ÁngelIn this paper it is described a Pilot that took place at Emídio Garcia School from Bragança, Portugal. The presented Pilot is based on a Challenge based Learning Approach, being an activity of the RoboSTEAM - Integrating STEAM and Computational Thinking development by using robotics and physical devices - ERASMUS+ Project. In the presented educational experiment it were used physical devices, being chosen the mBot robot, programmed using Scratch. The presented challenges had as research question a global problem that was Wildfires. Student had to propose and to develop solutions based on the use of robots to prevent and fight wildfires. The students that participated in the experiment were secondary school students, from Spain and Portugal, with their background in technology and arts respectively. Previously to the experiment the involved students filled a STEM semantic Survey and during the experiments their performance was evaluated.
- Programming of an educational robot to be applied in STEAM areasPublication . Camargo, Caio; Gonçalves, José; Lima, José; Duarte, LuísThe world is increasingly digital. Countries around the world strive to attract and prepare future generations to occupy the positions, where, for the most part, they will focus on Science, Technology, Engineering, Arts and Mathematics (STEAM). An approach already consolidated in the literature is the use of robots applied in education to encourage students to develop essential skills such as critical thinking, problem-solving and computational thinking. This work, linked to the RoboSTEAM project, aims to explore educational robots that can be applied in this context, considering that most approaches use LEGO’s platform, which can sometimes be difficult to access due to its high price. The robot used was the mBot in which it uses the mBlock 5 software to program it, from the MakeBlock Co. Ltd. company, being applied in two educational approaches during the execution of the project in which it is based on challenge based-learning methodology. A methodology for adding sensors to the mBot has been also explored. Finally, evaluations were made about the performance of students who participated in this project.
- Prototyping of a low-cost stroboscope to be applied in condition maintenance: an open hardware and software approachPublication . Brancalião, Laiany Suganuma; Camargo, Caio; Gonçalves, José; Lima, JoséThis paper aims to develop a low-cost stroboscope, which consists of an optical equipment capable of generating flashes of light at different frequencies, allowing to measure the rotation velocity of machines and contributing to maintenance processes in the industry. This device is based on the stroboscopic effect, a visual event that occurs when a continuous movement is presented by a series of samples, generated by flashes of light. When the frequency of the rotation movement is the same frequency of light pulses, the process will appear stationary. Based on the high cost of the commercial stroboscopes, it was developed a stroboscope prototype based on the Arduino platform, LED technology and 3D printing with an open hardware and software. The final prototype went through calibration and validation processes, achieving a performance very similar to a commercial instrument.
- Systematic literature review of realistic simulators applied in educational robotics contextPublication . Camargo, Caio; Gonçalves, José; Conde, Miguel Ángel; Rodríguez-Sedano, Francisco Jesús; Costa, Paulo Gomes da; García-Peñalvo, Francisco JoséThis paper presents a systematic literature review (SLR) about realistic simulators that can be applied in an educational robotics context. These simulators must include the simulation of actuators and sensors, the ability to simulate robots and their environment. During this systematic review of the literature, 559 articles were extracted from six different databases using the Population, Intervention, Comparison, Outcomes, Context (PICOC) method. After the selection process, 50 selected articles were included in this review. Several simulators were found and their features were also analyzed. As a result of this process, four realistic simulators were applied in the review’s referred context for two main reasons. The first reason is that these simulators have high fidelity in the robots’ visual modeling due to the 3D rendering engines and the second reason is because they apply physics engines, allowing the robot’s interaction with the environment.
