The term Industrie 4.0 carries the vision of smart factories, which automatically adapt to changes and assist the human as much as possible during operation and maintenance. This includes smart human machine interfaces, which reduce the chances of errors and help to make the right decisions. This paper presents an approach to equip the maintenance software running on a tablet PC with augmented reality functionality to be able to place virtual sticky notes at production modules. Additionally, these sticky notes are enriched with position information. The central element of this approach is an ontology-based context-aware framework, which aggregates and processes data from different sources. As a result, a tablet PC application was implemented, which allows displaying maintenance information as well as live plant process data in the form of augmented reality. More than 100 of those sticky notes can be placed using this system, whereas each note requires a file size of 12 to 16 kilo bytes. After placing a sticky note, the system recognizes it even if the camera's position is not exactly the same as during the placing process.

The aim of this article is to present a novel quaternion based control scheme for the attitude control problem of a quadrotor and experimentally evaluate its performance. A quaternion is a hyper complex number of rank 4 that can be utilized to avoid the inherent geometrical singularity when representing rigid body dynamics with Euler angles or the complexity of having coupled differential equations with the Direction Cosine Matrix (DCM). In the presented approach the novel contributions consist of: a) the quadrotor's attitude model and b) the proposed non-linear Proportional squared (P2) control algorithm, which have been proposed and experimentally evaluated fully in the quaternion space, without any transformations nor calculations in the Euler angle nor the DCM spaces. The established control scheme is combined with a quaternion based Madwick Complementary filter for estimating the attitude quadrotor's responses. Multiple experimental results, including the case where external disturbances are acting on the quadrotor, are being presented for proving the efficiency and the robustness of the proposed novel quaternion based controller.

An automated bead layout methodology is proposed for multi-pass welding on varying seam angle. This methodology will replace the tedious process of `teaching and playback' in the current line of robotic welding. To develop the proposed method, manual flux cored arc welding has been conducted on several workpieces. It is then ascertained that the bead size varies from 25 to 30 mm2 in a more ideal welding zone. Therefore, this leads to the assumption of a constant bead size for automated welding. Based on the results from this experiment, the bead layout and welding parameters for new workpiece with different seam angles can be determined. The simulation result show that a uniform bead layout is achieved.

Power line communication is becoming important as a leading technology in Smart Grid applications. This paper presents a new system to reduce the power consumption of the power line modems, implementing a zero-power stand-by feature. The incoming wake-up signal is as simple as a PLC frame and its associated energy is used to supply the wake-up logic. The system is mainly conceived for street lighting systems that use power line communication and where the stand-by power represents an issue because there are thousands of lamps in a city, and the total power consumption of the modems in stand-by mode is not negligible. This paper presents the architecture of the system, as well as the design choices. Experimental results of the system applied to a street light network show that it is possible to wake-up selectively a cluster of lamps up to a distance of about 250m.

In the nowadays highly unstable manufacturing market, companies are faced, on a daily basis, with important strategic decisions, such as “does the company has the necessary capacity to accept a high volume order?” or “what measures need to be implemented if the product demand increases x% a year?”. Decision-makers, i.e. company's managers, rely on their experience and insights supported by classical tools to take such decisions. Classical mathematical solvers or agent-based systems are typical architectural solutions to implement strategic planning tools to support decision-makers on this important task. Within the ARUM (Adaptive Production Management) project, a hybrid strategic planning tool was specified and developed, combining the optimization features of classical solvers with the flexibility and agility of agent systems. This paper briefly presents such architecture and focuses on the generation of the “what-if game” mechanism to support the generation of more intelligent and dynamic planning solutions.
在当今高度不稳定的制造业市场，公司每天都面临着重要的战略决策，例如“公司是否有必要的能力接受大量订单?”或者“如果产品需求每年增长x%，需要采取什么措施?”决策者，即公司的经理，依靠他们的经验和洞察力，由经典工具支持，做出这样的决定。经典的数学求解器或基于代理的系统是实现战略规划工具的典型体系结构解决方案，以支持决策者执行这一重要任务。在ARUM (Adaptive Production Management)项目中，设计并开发了一种混合战略规划工具，将经典求解器的优化特性与智能体系统的灵活性和敏捷性相结合。本文简要介绍了这种架构，并重点讨论了“假设游戏”机制的生成，以支持更智能和动态的规划解决方案的生成。

This paper deals with the identification of fractional models with one fractional parameter. This kind of models are capable to represent an extensive range of dynamics, including overdamped and oscillatory behaviors. The identification algorithm consists in applying an optimization function, starting from an initial point, that allows the program to calculate a very representative model of the process. The results demonstrate the usefulness and robustness of the tool, which can be employed to identify integer and fractional systems in an easy way and this can be later exploited for further studies, for example the development of tuning rules.

In this paper, a real-time control network based on Ethernet and FireWire is presented, where Ethernet provides a convenient, cross-platform interface between a central control PC and a FireWire subnetwork that contains multiple distributed nodes (I/O boards). Real-time performance is achieved because this architecture limits the number of Ethernet transactions on the host PC, benefits from the availability of real-time Ethernet drivers, and uses the broadcast and peer-to-peer capabilities of FireWire to efficiently transfer data among the distributed nodes. This approach and resulting benefits are comparable to EtherCAT, but preserves existing investments in FireWire-based controllers and relies only on conventional, vendor-neutral network hardware and protocols. The system performance is demonstrated on the da Vinci Research Kit (dVRK), which consists of 8 FireWire nodes that control 2 Master Tool Manipulators (MTMs) and 2 Patient Side Manipulators (PSMs), for a total of 28 axes. This approach is generally applicable to interface existing FireWire-based systems to new control PCs via Ethernet or to serve as an open-source alternative to EtherCAT for new designs.

The protection and preservation of cultural heritage for generations is a challenging task. Therefore this paper describes a system for non-contact and safe 3D measurement and digitization of unique cultural objects and craftworks. The aim of this project is the precise 3D capturing and the semi-automated processing of smaller and medium-sized cultural objects. Therefore this paper suggests a system that allows semi-automated usage in a museum environment using a collaborative robot equipped with comprehensive safety sensor technology. So further security mechanisms such as safety barriers are no longer necessary. To avoid a collision with the examined object the path planning and collision prevention system uses a Time of Flight (ToF) camera to detect the environment and the object. The system also continuously monitors the working environment to detect intrusion. If working environment is violated in scan process, the system changes to a safe state. Another system (ToF) is required to position the 3D measurement system (structured-light 3D scanner) in front of the cultural object. The assistant system measures the object depth in a preliminary scan.

As a standardized communication protocol, OPC UA is the main focal point with regard to information exchange in the ongoing initiative Industrie 4.0. But there are also considerations to use it within the Internet of Things. The fact that currently no open reference implementation can be used in research for free represents a major problem in this context. The authors have the opinion that open source software can stabilize the ongoing theoretical work. Recent efforts to develop an open implementation for OPC UA were not able to meet the requirements of practical and industrial automation technology. This issue is addressed by the open62541 project which is presented in this article including an overview of its application fields and main research issues.

In this paper an innovative concept for a fault prevention in industrial automation systems is presented. The goal of this concept is the avoidance of downtimes, by means of the early identification of fault developments during runtime. Additionally, in comparison to common fault prevention solutions, today's complexity of prevention processes and the increasing amount of data is aimed to be reduced in this concept. In order to fulfill these requirements, a methodology has been developed, which helps to identify fault development characteristics after a single fault occurrence. By means of this information, the same system or similar systems can be inspected for this definite fault development in the future in order to avoid reoccurrence of this particular fault or failure. Thus, the fault-based identification and inspection helps to increase systems' availability, which is demanded amongst other things due to the high productivity requirements in industry.
