Sustainability and sustainable development concepts are frequently the driving force for research related to optimizing energy consumption and material use in order to reduce the carbon footprint for different products. EcoBotics aims to analyse the question of sustainability in the area of robotics. In this paper, as a first example of EcoBotics, it is examined what are the advantages and challenges of exchanging the aluminium structure of lightweight robot arms with a sustainable material. Bamboo is used in order to exemplify a sustainable material, but the challenges and the proposed solutions for open problems are valid for any material causing a robot structure with low stiffness.

Quality-oriented Design of Rotor Assembly Strategies for Electric Drive Production Systems

Procedia CIRP 2015年 36卷 141-146页

作者： Marcello Colledani Anteneh Yemane Daniel Coupek Armin Lechler Politecnico di Milano Mechanical Engineering Department Via la Masa 1 20156 Milano Italy Institute for Control Engineering of Machine Tools and Manufacturing Units (ISW) Seidenstraße 36 70174 Stuttgart Germany

Electric mobility is an emerging industrial sector that requires innovative quality control methods as common manufacturing and testing methods of combustion engines cannot be transferred directly to electric motors. This paper presents new solutions for the quantitative evaluation of quality-oriented rotor assembly strategies in electric drive production systems. The proposed methods assist the analysis of productivity and quality performance of two different assembly strategies namely selective assembly and sequential assembly. The impacts of these approaches are validated within a real industrial context, where state of the art quality and process control technologies show strong limitations. Experimental results have shown that the application of the proposed strategies yield a significant improvement in the production rate of conforming parts of the system. Moreover, the general applicability of these approaches to similar industrial problems encourages their adoption for defect reduction and elimination thus paving the way to zero-defect manufacturing paradigm.

Hardware Trojans (HTs) are identified as an emerging threat for the integrity of Integrated Circuits (ICs) and their applications. Attackers attempt to maliciously manipulate the functionality of ICs by inserting HTs, potentially causing disastrous effects (Denial of Service, sensitive information leakage, etc.). Over the last 10 years, various methods have been proposed in literature to circumvent HTs. This article introduces the general context of HTs and summarizes the recent advances in HT detection from a French funded research project named HOMERE. Some of these results will be detailed in the related special session.

The software design of current CNC systems is of limited suitability for real parallel execution on multicore systems. Even though CNC systems are rudimentarily designed in a modular way, a good load balancing and therefore an efficient use of multiple processor cores is not satisfactorily to be accomplished, as the modularization is not sophisticated enough. A parallelization of CNC functions and algorithms would remedy this deficit. This paper presents an analysis on which parts of a CNC system show the capability for parallelization. Furthermore an approach is presented on how the parallelization of a specific function, namely the look-ahead function, can be accomplished. © Copyright 2014 by DEStech Publications, Inc.

The productivity of milling processes is limited by the occurrence of chatter vibrations. The correlation of the maximum stable cutting depth and the spindle speed can be shown in a stability lobe diagram (SLD). Today it is a great effort to estimate the SLD. Lot's of experiments are necessary to measure the SLD or derive a detailed mathematical model to calculate the SLD. Moreover not only cutting depth, but also the cutting width should be taken into account. This paper presents an approach to learn the multidimensional stability lobe diagram (MSLD) during the production based on continuously measured signals using a support vector machine. The support vector machine is extended to make it capable for continuous learning and time-variant systems. The process conditions are classified as stable or unstable. The learned MSLDs are very similar to the analytically calculated MSLDs. Changes over time in the system dynamics can also be learned by the proposed algorithm. © Copyright 2014 by DEStech Publications, Inc. All rights reserved.

Robotic structures have been a subject to continuous innovation since their presence. This paper presents a new approach to solve the inverse kinematics problem of the "HIDRA" (HIghDexterityRoboticArm). A SimMechanics trunk model has been developed based on which a position control algorithm will be developed. The published experimental results, coming from numerical simulations, validate the similarity of our kinematic model, and our new approach of determining the lengths of the bellows. This new approach presents the correlation between the physical characteristics and the elongation provided by variable air pressure. © VDE VERLAG GMBH Berlin Offenbach.

Efficient Combination of Topology and Parameter Optimization

Open Journal of Optimization 2014年第3期3卷 19-25页

作者： Yusheng Lin Zheng Sun Alexandru Dadalau Alexander Verl Institute for Control Engineering of Machine Tools and Manufacturing Units (ISW) University of Stuttgart Stuttgart Germany

This paper presents a combination method of Particle Swarm Optimization (PSO) and topology optimization. With this method a better result can be achieved compared with the sequential application of these two optimization methods. It inherits the ability in finding global optimum from PSO and also suits for discretized design domain. Some special schemes are used in order to provide higher computation efficiency. This method has only been tested with a convex optimization problem. The application in case of a concave problem will be a future study.

This paper presents a factorial analysis of the compensation of dynamic characteristics of a special class of reconfigurable haptic device. The haptic device is a reconfigurable parallel structure with having a revolute joint as actuated joint. In order to decrease the inertia and the moving mass of the mechanism this actuated joint is attached to the fixed platform of the mechanism. The haptic device interacts with a human operator by the means of its end effector. The dynamic compensation takes in consideration the mechanical properties of the robot in order to achieve a "transparent" mechanical structure. A "transparent" mechanical structure implies that forces or movements rendered through a haptic device remain unaltered due to friction, inertia or gravity (i.e. dynamic behavior) of the structure. Interaction with a virtual world has to be an immersive experience. The 'transparent' mechanical structure achieved by dynamic compensation facilitates the immersiveness of the haptic experience. © VDE VERLAG GMBH Berlin Offenbach.

Procedia Technology 2014年 15卷 595-604页

作者： Christian Friedrich Armin Lechler Alexander Verl Institute for Control Engineering of Machine Tools and Manufacturing Units Seidenstraße 36 Stuttgart 70174 Germany

The technological change of the maintenance process from reactive to preventive methods correlates with the awareness, that maintenance is not only a cost factor but a business process, which is part of the added value of a company. The automation of maintenance tasks allows to plan the operation optimally and fast. This creates a significant economic advantage for the manufacturing industry and is the opportunity for autonomous systems to show their potential. The following work gives an introduction into the possibilities to automate the maintenance process, suggestions and a probable concept architecture for automated services and maintenance.
