Mecanum wheel robotic platform for educational purposes: a cost-effective approach

This paper presents a cost-effective approach of a mecanum wheel robotic platform for educational propose on the development of an autonomous or remote controlled mobile robot with a four-wheel mecanum drive train. The main structure of the mobile robot was developed in Solidworks and it was built using additive manufacturing to validate in a real scenario. The main objective of developing this type of mobile platform was the ability to transport different types of cargo or robotic arm on industrial spaces or on rough terrain, since the implemented suspension mechanism allows the wheels contact to the floor. Another important objective is the maneuverability and the capacity to be guided in various environments, a great advantage in this type of mobile platform. An additional advantage of the developed mobile robot is the easy way to reconfigure the structure for new acquired parts.The authors acknowledge the support of RD Unit SYSTEC-Base (UIDB/00147/2020) and Programmatic (UIDP/00147/2020) funds, and also the support of Project Warehouse of the Future (WoF), with reference POCI-01-0247-FEDER-072638, co-funded by European RegionalDevelopment Fund (ERDF), through the Operational Programme for Competitiveness and Internationalization (COMPETE 2020)info:eu-repo/semantics/publishedVersio

A robot localization proposal for the RobotAtFactory 4.0: A novel robotics competition within the Industry 4.0 concept

Robotic competitions are an excellent way to promote innovative solutions for the current industries’ challenges and entrepreneurial spirit, acquire technical and transversal skills through active teaching, and promote this area to the public. In other words, since robotics is a multidisciplinary field, its competitions address several knowledge topics, especially in the STEM (Science, Technology, Engineering, and Mathematics) category, that are shared among the students and researchers, driving further technology and science. A new competition encompassed in the Portuguese Robotics Open was created according to the Industry 4.0 concept in the production chain. In this competition, RobotAtFactory 4.0, a shop floor, is used to mimic a fully automated industrial logistics warehouse and the challenges it brings. Autonomous Mobile Robots (AMRs) must be used to operate without supervision and perform the tasks that the warehouse requests. There are different types of boxes which dictate their partial and definitive destinations. In this reasoning, AMRs should identify each and transport them to their destinations. This paper describes an approach to the indoor localization system for the competition based on the Extended Kalman Filter (EKF) and ArUco markers. Different innovation methods for the obtained observations were tested and compared in the EKF. A real robot was designed and assembled to act as a test bed for the localization system’s validation. Thus, the approach was validated in the real scenario using a factory floor with the official specifications provided by the competition organization.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES (PIDDAC) to CeDRI (UIDB/ 05757/2020 and UIDP/05757/2020) and SusTEC (LA/P/0007/ 2021).

Systematic mapping literature review of mobile robotics competitions

This paper presents a systematic mapping literature review about the mobile robotics competitions that took place over the last few decades in order to obtain an overview of the main objectives, target public, challenges, technologies used and final application area to show how these competitions have been contributing to education. In the review we found 673 papers from 5 different databases and at the end of the process, 75 papers were classified to extract all the relevant information using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. More than 50 mobile robotics competitions were found and it was possible to analyze most of the competitions in detail in order to answer the research questions, finding the main goals, target public, challenges, technologies and application area, mainly in education.info:eu-repo/semantics/publishedVersio

Learning robotics: a review

Purpose of Review: With the growing interest for STEM/STEAM, new robotic platforms are being created with different characteristics, extras and options. There are so many diverse solutions, that it is difficult for a teacher/student to choose the ideal one. This paper intends to provide an analysis to the most common robotic platforms existent on the market. The same is happening regarding robotic events all around the world, with objectives so distinctive, and with complexity from easy to very difficult. This paper also describes some of those events which occur in many countries. Recent Findings: As the literature is showing, there has been a visible effort from schools and educators to teach robotics from very young ages, not only because robotics is the future, but also as a tool to teach STEM/STEAM areas. But as time progresses, the options for the right platforms also evolves making difficult to choose among them. Some authors opt to first choose a robotic platform and carry on from there. Others choose first a development environment and then look for which robots can be programmed from it. Summary: An actual review on learning robotics is here presented, firstly showing some literature background on history and trends of robotic platforms used in education in general, the different development environments for robotics and finishing on competitions and events. A comprehensive characterization list of robotic platforms along with robotic competitions and events is also shown

Promotion of STEM education in Vocational and Professional Education and Training (VPET)

Vocational and Professional Education and Training (VPET) enhances learners to acquire professional knowledge, apply practical skills and develop positive workplace attitudes to support the long-term development of a country or a city. Established in 1982, the Vocational Training Council (VTC) is the largest vocational and professional education and training provider (VTC 2016) in Hong Kong. Through a wide range of pre-employment and in-service programmes, it establishes valuable credentials for approximately 250,000 students each year with internationally recognised qualifications. As a member institution of VTC, the Hong Kong Institute of Vocational Education (IVE) offers fulltime and part-time programmes - covering an array of disciplines and at levels ranging from higher diploma to certificate - nurturing talents valued by industries. STEM (Wikipedia 2016), an acronym that refers to the academic disciplines of Science, Technology, Engineering and Mathematics. STEM (Education Bureau, Hong Kong 2015) plays a pivotal role in educating students to meet the rapid changes and continuous challenges in our society and all over the world due to swift economic, scientific and technological developments. In alignment with this worldwide trend in education, the promotion of STEM in VPET, especially in the Applied Science (AS), Engineering (ENG) and Information Technology (IT) Disciplines, has been the major focus of development in VTC for years. In this paper, various STEM education strategies under VTC will be addressed. One important milestone is the setup of STEM Education Centre to serve as a platform for cross-disciplinary projects for STEM students and to promote STEM education to the public and primary/secondary school students through seminars, workshops and international events. Pertaining to the internationalisation of vocational and professional education, the implementation of exchange programmes in STEM study with overseas countries, local students and their counterparts is another strategic development of VTC. It broadens students’ horizon and generates their inspirations in team work and collaboration projects. The Engineering Discipline in IVE has completed a number of successful workshops with MIT (Massachusetts Institute of Technology) students, in which IVE students were inspired to explore their learning, employing different learning methods and have gained insights into the development of STEM industries, as well as interests in STEM subjects. In June 2016, as another important event to internationalise VPET, VTC organised an international STEM Students Forum in the WorldDidac Asia in Hong Kong. This provided a golden opportunity for the local and overseas students from Australia, UK and Singapore to exchange a wealth of information from different perspectives in STEM education. A similar international STEM forum is underway for 2017 covering sessions with outstanding STEM projects from academic institutions, to study STEM teaching and learning pedagogy, and to look into the STEM project development with VTC students. Other strategies such as Science and Mathematics Help Desk, Technology Enhanced Learning and Teacher Support will also be discussed in the paper
