- Localização e navegacão de um robô móvel omnidirecional: caso de estudo da competição robot@factoryPublication . Costa, Paulo Gomes da; Moreira, Nuno; Campos, Daniel; Gonçalves, José; Lima, José; Costa, PedroThe Robot@Factory competition, was recently included in Robotica, the main Robotics Portuguese Competition. This robot competition takes place in an emulated factory plant, where Automatic Guided Vehicles (AGVs) must cooperate to perform tasks. To accomplish their goals the AGVs must deal with localization, navigation, scheduling and cooperation problems, that must be solved autonomously. The presented robot competition can play an important role in education due to the inherent multi-disciplinary concepts that are involved,motivating students to technological areas. It also plays an important role in research and development, because it is expected that the outcomes that will emerge here, will later be transfered to other application areas, such as service robots and manufacturing. By presenting a scaled down factory shop floor, this competition creates a benchmark that can be used to compare different approaches to the problems that arise on this kind of environments. Also, the ability, in some restricted areas, to alter the environment, can promote the test and evaluation of different localization mechanisms, something that is usually, more restricted in other competitions, opening this area to be explored and benchmarked. In this paper it is discussed one of the possible approaches, that can be applied to the robot competition, serving as reference to the actual and new potential participating teams.
- Localization and navigation of an omnidirectional mobile robot: the robot@factory case studyPublication . Costa, Paulo Gomes da; Moreira, Nuno; Campos, Daniel; Gonçalves, José; Lima, José; Costa, PedroThe Robot@Factory competition was recently included in Robotica, the main Portuguese Robotics Competition. This robot competition takes place in an emulated factory plant, where Automatic Guided Vehicles (AGVs) must cooperate to perform tasks. To accomplish their goals, the AGVs must deal with localization, navigation, scheduling and cooperation problems that must be solved autonomously. This robot competition can play an important role in education due to its inherent multidisciplinary approach, which can motivate students to bridge different technological areas. It can also play an important role in research and development, because it is expected that its outcomes will later be transferred to real-world problems in manufacturing or service robots. By presenting a scaled-down factory shop floor, this competition creates a benchmark that can be used to compare different approaches to the challenges that arise in this kind of environments. The ability to alter the environment, in some restricted areas, can usually promote the test and evaluation of different localization mechanisms, which is not possible in other competitions. This paper presents one of the possible approaches to build a robot capable of entering this competition. It can be used as a reference to current and new teams.
- Modeling and simulation of a hacked neato XV-11 laser scannerPublication . Campos, Daniel; Santos, Joana Patrícia Friães; Gonçalves, José; Costa, Paulo Gomes daLaser scanners are widely used in mobile robotics localization systems but, despite the enormous potential of its use, their high price tag is a major drawback, mainly for hobbyist and educational robotics practitioners that usually have a reduced budget. This paper presents the modeling and simulation of a hacked Neato XV-11 Laser Scanner, having as motivation the fact that it is a very low cost alternative, when compared with the current available laser scanners. The modeling of a hacked Neato XV-11 Laser Scanner allows its realistic simulation and provides valuable information that can promote the development of better designs of robot localization systems based on this sensor. The sensor simulation was developed using SimTwo, which is a realistic simulation software that can support several types of robots.
- Prática de ensino supervisionada. Aprendizagem da criança em contacto com a naturezaPublication . Campos, Daniel; Sanches, AngelinaO presente relatório incide sobre a prática de ensino supervisionada desenvolvida em contextos de creche, jardim de infância e 1.º ciclo do ensino básico, no âmbito de um mestrado que habilita para estes níveis educativos. Tem como base de reflexão a aprendizagem da criança em contacto com a natureza, com o objetivo de obter respostas sobre as potencialidades e oportunidades que as instituições indicadas proporcionam à criança. Considerando que os espaços exteriores de recreio e do meio envolvente proporcionam oportunidades diversas de aprendizagem, entendemos conhecer como estes são utilizados e valorizados no processo de ensino e aprendizagem das crianças. Assim, a abordagem insere-se mais na área do Conhecimento do Mundo prevista nas Orientações Curriculares para a Educação Pré-Escolar e na de Estudo do Meio do Programa do 1.º Ciclo do Ensino Básico, mas abrange a exploração de conteúdos nas outras diversas áreas e domínios curriculares. As crianças devem conhecer o mundo que as circunda, pelo que devem usufruir de oportunidades de contactar com o mesmo, desde as idades mais precoces, de modo a que possam explorar, observar e criar tendo à sua disposição materiais, incluindo os do mundo natural. O estudo apresenta uma linha orientadora com caraterísticas de investigação-ação, centrando-se em saber como valorizar a natureza enquanto recurso educativo potenciador de aprendizagens múltiplas. Os resultados evidenciam ser importante proporcionar às crianças oportunidades de observação e manipulação dos recursos que a natureza proporciona e de aprender a valorizá-la e promover a sua preservação.
