Precision robotic inline metrology for freeform surfaces

High precision in-line measurements on free form surfaces are considered a key factor for the industrial production of the future. Robot-based measurement systems provide the required flexibility but are typically lacking the required precision. The scope of this project is the development of a measurement platform designed as end effector for industrial robots, which carries a measurement or inspection tool and compensates for environmental disturbances, enabling precision inline measurements on arbitrarily oriented surfaces.

Hybrid reluctance actuators for high precision motion

Next-generation high-quality motion systems require high-precision actuators with higher energy efficiency and larger force to improve the system throughput. Particularly, actuators with a motor constant higher than comparable voice coil actuators are highly desired. This project investigates hybrid reluctance actuators (HRAs) with guiding flexures as a promising candidate of the next-generation systems. Weiterlesen →

Aktive Turbulenzunterdrückung für Flugzeuge – SmartWings

Flugturbulenz stellt ein ungelöstes Problem für die Luftfahrt dar. Die Untersuchung von intelligenten Flügelstrukturen, die Turbulenzen messen und Störungen aktiv durch Klappenausschläge kompensieren, soll es zukünftig ermöglichen, Turbulenzen direkt und zuverlässig zu durchfliegen. Weiterlesen →

TracSat

The precise tracking of high velocity satellites with ground based optical telescopes is a prerequisite for a number of future applications such as optical satellite communication, observation of space debris or satellite laser ranging. To achieve this goal, good mechatronic design as well as high performance control are necessary. Together with our industrial partner, ASA Astrosysteme GmbH, this project aims on increasing the achievable precision and tracking velocity of existing ASA ground stations. Weiterlesen →

Fundamentals of opto-mechatronic systems (OMC)

Currently innovation is taking place at the border of disciplines rather than in one individual field of engineering. This particularly holds for application domains that span more than one field of engineering, since a high level of system integration from different disciplines provides solutions that a single domain alone cannot provide. As an example, the combination of optics and mechatronics form the interdisciplinary field of opto-mechatronics. Weiterlesen →

Atomic Force Microscopy capable of vibration isolation (Vibrostop AFM)

An atomic force microscope (AFM) can image and inspect a sample surface with high resolution by scanning a probe with a sharp tip over the sample. During scanning, the vertical position of the probe with respect to the sample typically needs to be regulated with nanometer resolution. For the required high resolution, AFMs are sensitive to vibrations transmitted from the floor dependent on their design. Weiterlesen →

Automated in-line metrology for nanopositioning systems (aim4np)

Robot based in-process metrology is a key enabling technology for upcoming production systems and is considered as one of the most important preconditions for future production. Measuring properties at the nanometer scale such as topography, morphology and roughness within a production line becomes increasingly important for quality control and process monitoring tasks to make high tech production more efficient.

Precision actuator selection

Many applications require positioning with nanometer resolution. They include lithographic equipment for semiconductor and liquid crystal display (LCD) manufacturing and data storage devices such as hard disk drives (HDDs) and optical disk drives (ODDs) (e.g. CD/DVD/Blu-ray), as well as scientific instruments such as atomic force microscopes (AFMs). The achievable positioning resolution of these systems is typically influenced by vibrations transmitted from the floor. Weiterlesen →
