We show how to extend electrokinetic tweezing, which can manipulate any visible particles and has more favorable force scaling than optical actuation (enabling manipulation of nanoscale objects to nanoscopic precision) from 2-dimensional control to the third dimension (3D). A novel and practical device is presented that can create both planar and vertical flows and electric field modes. Feedback control algorithms are extended and demonstrated in realistic simulations to show 3D manipulation of particles. The design and control results presented here are the essential next step to go from current 2D manipulation capabilities to an experimental demonstration of nanoprecision 3D electrokinetic tweezing in a microfluidic system. Doing so requires integration with vision-based nano-precise 3D particle imaging, a capability that has been shown in the literature and which we are now combining with the 3D actuation and control methods demonstrated here.

This paper copes with the problem of finding a collision-free path for a hand-arm robotic system from an initial unconstrained configuration to a final grasping (or preshape) one. The aim is to obtain a natural motion as a sequence of human-like postures that both capture the coupling that there exist between the fingers of the human hand and also maintain the palm oriented towards the object to be grasped. The proposed method is a sampling-based approach whose efficiency relies in the reduction of the dimensionality obtained by considering, for the finger joints, a subspace determined by the main principal motion directions that capture the coupling and, for the position and orientation of the palm, the submanifold that satisfies the orientation constraint. The approach is illustrated with an example and compared to the case where no virtual constrains are used, validating the proposal.

Cooperating robots are a flexible solution for handling and assembling large-scale objects, but they cause high procurement costs and personnel costs for programming. The purpose of the project is to simplify the programming by a new hardware concept of the control system and to guarantee an easy reconfiguration to flexibly adapt and re-use robot cells. Derived from existing solutions, a modular control system had been developed to simplify the programming procedure. It subordinates all robots under an independent central control module, which leads to equality, exchangeability and reconfigurability of the robots. The control system was implemented in a layout of simple kinematic units which can be easily reconfigured within an assembly platform. Therefore the modularity of the control system must follow the modularity of the complete mechatronic system. The control concept is independent from the robot manufacturer and will be validated for different industrial robots in future research. The project targets on applications in aircraft production, where large-scale objects in small batches have to be assembled with cooperating robots.

The market for electric motors in general machine applications and especially in electric driven vehicles has changed tremendously over the last years, as new materials and innovative electronics enable manufacturers to develop electric motors with highest energy densities in applications ranging from miniature up to large industrial motors. Within this development, considerations towards manufacturing and assembly technologies have become a topic of interest, especially the handling of high coercive neodymium iron boron (NdFeB) or samarium cobalt (SmCo) magnet materials for State of the Art permanent magnet excited machines (PM machines). Processes such as positioning and gluing of magnets or the integration of magnetizers into assembly are challenging current methods. Flexible production processes for rapid ramp up and small batch sizes are needed for economic manufacturing. In this paper innovative handling and assembly solutions for magnetized high coercive permanent magnets, developed at the Institute for Manufacturing Automation and Production Systems (FAPS), are presented.

Industries and homes are being swept up by the tide of automation which began with the development of computers and robots. Since the role of robots has become critical in automation industry, it has become an important issue for robots to behave and make judgments like humans when grabbing things. This study was conducted to accurately find the axis of an object when the object needs to be modeled for robots to make judgments and grabbing objects. Cylindrical objects are not difficult to estimate their axis if they have only one axis, but torus shapes have radii and axes in general. So we suggest a new method for a central axis and radius estimation for torus modeling based on: 1) 3D edge based segmentation (contour), 2) radius estimation using two surface's point normal vectors, 3) find the central axis using histogram analysis and 4) verification from projected 2D image and superquadrics equation. In this paper, we show torus modeling result from central axis and two radii estimation.

Today's processes in micro- and nanofabrication include several critical dimension metrology steps to guarantee device performance. Especially in the manufacturing process of novel disruptive photonic devices and nanoelectronic circuit architectures, new 3D acquisition and visualization techniques for metrology are required. Two of the most important parameters are the line width and sidewall roughness of vertical interconnects and nanooptical structures. The measurement of these parameters becomes increasingly challenging as the continuous shrinking of dimensions requires higher lateral resolution. The AFM has become a standard and widely spread instrument for characterizing such nanoscale devices and can be found in most of today's research and development areas. However, the characterization of three dimensional high-aspect ratio and sidewall structures is still a bottleneck. Novel exchangeable and customizable scanning probe tips, so-called NanoBits, can be attached to standard AFM cantilevers offering unprecedented freedom in adapting the shape and size of the tips to the surface topology of the specific application. In order to realize the in-situ exchange of NanoBits within the AFM environment the NanoBits have to be provided in a freestanding way that allows the AFM cantilever to be aligned and connected to the NanoBits. Due to the fact that direct microfabrication of such structures is still challenging, a nanorobotic preassembly of NanoBits cartridges is reasonable. These cartridges are intended to contain several NanoBits with a variety of different tip-shapes.

The current paper studies the concept of learning pallets following the autonomy paradigm; in a Conwip control job-shop/ open-shop system. To realize learning capability for pallets several advantages and methodologies can be employed. Among them are the privileges of closed-loops in Conwip system as well as application of evolutionary intelligence for inspiring learning. Specifically, some features of genetic algorithm (GA) can be used to produce new alternatives and avoid local traps in a decentralized approach, though the GA is a global search method. In addition, fuzzy inference system is employed to distinguish the dynamisms of each station as well as of the entire system, concerning vagueness in real time information, and uncertainty in processing sequence and times. It is shown here that learning pallets (Lpallets) are presenting better records in terms of some criteria, e.g., makespan.

Assembly of products from the micro and the meso domain like micro-optical systems and/or micro-mechanical actuators is often done manually and with increasing product volumes more and more automatically. According to the specific needs associated with the size, such implementations should be realised in an adapted way without just downscaling macro process and equipment solutions. This leads to the Mini-/Microfactory concepts which have been under development since years in different working groups. The paper presents the new microFLEX concept aiming at space- and energy-saving automation solutions for the meso and micro domain. Based on the results of an investigation of the assembly of a fine mechanical reference product, the requirements list is generated and the basic logistic approach will be derived. The table-based concept is outlined and a simple scenario is used to illustrate the usability of the system.

Today's turbulent production environment calls for adaptive and rapidly responding production systems that can adjust to required changes in products, production volumes and unexpected failure situations. Holonic manufacturing systems aim to offer a solution for changeability requirements by providing self-organizing capabilities. This paper presents a concept of a holonic manufacturing framework and its implementation into a laboratory environment. The adaptivity of the presented holonic system rests on SOA-based communication and negotiation between entities through open interfaces, and matching of resource capabilities against product requirements.

This study focused on the systematic error compensation of CNC machines via software way. The method is based on machining test pieces, measuring same for finding the systematic errors of a machine, forming an error map and using the map for correcting the tool paths of the NC-program. Technically, it was shown that by measuring the systematic errors of machines and numerically calculating new, compensated parameters, the precision of aging machines could be substantially improved. Resultingly, the method extends the lifetime of an older machine, postponing the need for new investment for several years.
