Author supplied: Abstract—The growing importance and impact of new technologies are changing many industries. This effect is especially noticeable in the manufacturing industry. This paper explores a practical implementation of a hybrid architecture for the newest generation of manufacturing systems. The papers starts with a proposition that envisions reconfigurable systems that work together autonomously to create Manufacturing as a Service (MaaS). It introduces a number of problems in this area and shows the requirements for an architecture that can be the main research platform to solve a number of these problems, including the need for safe and flexible system behaviour and the ability to reconfigure with limited interference to other systems within the manufacturing environment. The paper highlights the infrastructure and architecture itself that can support the requirements to solve the mentioned problems in the future. A concept system named Grid Manufacturing is then introduced that shows both the hardware and software systems to handle the challenges. The paper then moves towards the design of the architecture and introduces all systems involved, including the specific hardware platforms that will be controlled by the software platform called REXOS (Reconfigurable EQuipletS Operating System). The design choices are provided that show why it has become a hybrid platform that uses Java Agent Development Framework (JADE) and Robot Operating System (ROS). Finally, to validate REXOS, the performance is measured and discussed, which shows that REXOS can be used as a practical basis for more specific research for robust autonomous reconfigurable systems and application in industry 4.0. This paper shows practical examples of how to successfully combine several technologies that are meant to lead to a faster adoption and a better business case for autonomous and reconfigurable systems in industry.
Standard mass-production is a well-known manufacturing concept. To make small quantities or even single items of a product according to user specifications at an affordable price, alternative agile production paradigms should be investigated and developed. The system presented in this article is based on a grid of cheap reconfigurable production units, called equiplets. A grid of these equiplets is capable to produce a variety of different products in parallel at an affordable price. The underlying agent-based software for this system is responsible for the agile manufacturing. An important aspect of this type of manufacturing is the transport of the products along the available equiplets. This transport of the products from equiplet to equiplet is quite different from standard production. Every product can have its own unique path along the equiplets. In this article several topologies are discussed and investigated. Also, the planning and scheduling in relation to the transport constraints is subject of this study. Some possibilities of realization are discussed and simulations are used to generate results with the focus on efficiency and usability for different topologies and layouts of the grid and its internal transport system. Closely related with this problem is the scheduling of the production in the grid. A discussion about the maximum achievable load on the production grid and its relation with the transport system is also included.

In Europe nearly 10% of the population suffers from diabetes and almost 1% from Rheumatoid Arthritis which can lead to serious problems with mobility and active participation, especially in the ageing population. Pedorthists deliver personalised designed and manufactured orthopaedic footwear or insoles for these patients. However, despite their often laborious efforts upfront, the industry has very little means to quantify how successful the fitting and function of a shoe is. They have to rely on subjective, qualitative measures such as client satisfaction and diminishing of complaints. Although valuable, the need for objective quantitative data in this field is growing. Foot plantar pressure and shear forces are considered major indicators of potential foot problems. Devices to measure plantar pressure slowly gain terrain as providers of objective quantitative data to guide orthotic design and manufacturing. For shear forces however, measuring devices are not yet commercial available. Although shear forces are considered as a major contributor to ulcer formation in diabetic feet, their exact role still requires elucidation and quantification. This project aims to develop a prototype of an in-shoe wearable device that measures both shear forces and pressure using state-of-the-art developments in sensor technologies, smart textiles and wireless data transfer. The collaboration of pedorthists’ small and medium-sized enterprises (SME)’s with medical device engineering companies, knowledge institutes,technical universities and universities of applied sciences in this project will bring together the different fields of expertise required to create an innovative device. It is expected that the tool will be beneficial to improve the quality of pedorthists’ services and potentially reduce health insurance costs. Furthermore, it can be used in new shear forces research and open new business potential. However, the eventual aim is to improve patient care and help maintain personal mobility and participation in society.
