Automated manipulation of micro- and nanosized objects using robotic setups constitutes a major challenge due to the force-scaling laws and the limited control possibilities on that scale. This paper presents a new developed approach for automated manipulation of individual colloidal particles using a dedicated dual-probe setup inside a scanning electron(More)
This paper presents an automated handling approach of two-dimensional nanomaterials using a robotic setup inside a high-resolution scanning electron microscope. Applying image processing of the visual feedback provided by the electron microscope, a fully automated sequence is developed to align a robotic driven force sensor with sub micrometer accuracy and(More)
This paper presents reproducible pick and place handling of particles within the sub micron range. The handling strategy is based on a robotic dual probe setup that is integrated into a high resolution scanning electron microscope. By purposeful utilization of the predominant adhesive forces on the nanoscale, this setup facilitates the assembly of overall(More)
In micro- and nanorobotics, it is important to increase closed-loop performance to achieve high-throughput for industrial applications. By using dedicated line scans instead of scanning microscope image acquisition, bottlenecks such as limited update rate, long latency and unpredictable jitter can be overcome. Earlier experiments used the line-scan approach(More)
This paper presents a new experimental approach for pick and place handling of few-layer graphene nanomembranes with side length of 10 μm and below. In the as-received condition, the membranes are freely suspended on a grid which is covered with a lacey carbon film. Using focused ion beam cutting and a nanorobotic driven tungsten tip, selected(More)
Object-detection and classification is a key task in micro- and nanohandling. The microscopy image is often the only available sensor to detect information about the positions and orientations of objects. Recently, Field Programmable Gate Arrays (FPGAs) have been used for scanning electron microscope (SEM) image acquisition. Such an FPGA image acquisition(More)
Fabrication of tailored photonic structures with sufficient precision is a major topic in photonics since decades. However, until now, the assembly of photonic structures in order to control light propagation in all three spatial dimensions remains challenging. This paper presents a reliable approach for fabricating three-dimensional structures consisting(More)
