Leading with empathy is a hallmark of many leadership strategies. As members of the 2021–2022 cohort of the Senior Leadership Academy (SLA) run by the Council of Independent Colleges (CIC) and the American Academic Leadership Institute (AALI), we set out to understand what leading with empathy should look like. Simultaneously, as part of our introversion and leadership group project, we conducted...
This paper describes the laser-based structuring of piezoceramic actuators used in a mobile microrobot. The actuator has to meet several requirements. Firstly, the achieved positioning accuracy of the mobile platform should be in the single nanometer range. This leads to the use of piezoelectric ceramics, which support this demand. Secondly, as the robot needs to have up to three degrees of freedom...
Maintaining large code bases can be a challenging endeavour. As new libraries, APIs and standards are introduced, old code is migrated to use them. To provide as clean and succinct an interface as possible for developers, old APIs are ideally removed as new ones are introduced. In practice, this becomes difficult as automatically finding and transforming code in a semantically correct way can be challenging,...
To date, determining depth information for robotic handling in a scanning electron microscope is a challenging problem without a versatile solution. In this paper, focus-based as well as other depth detection methods are analyzed showing limitations in terms of accuracy and speed. To overcome these limitations, existing focus-based approaches are combined with a new line-scan based position tracking...
Separation and palletizing of microparts is a prerequisite for microhandling and microassembly, especially for components such as microspheres that cannot be efficiently produced and transported in a well-ordered form. Two mi-crorobots equipped with a microgripper and a sharp tungsten tip, respectively, can be effectively utilized to solve this task cooperatively. Based on a powerful visual feedback...
This paper describes a new, automated positioning system that uses the scanning electron microscope as a fast, high-resolution sensor system. With two line scans and low computational overhead, the exact position of a reference pattern is determined. Using a customized external scan generator and scanning algorithm, the bottleneck of image acquisition is bypassed and the position tracking system can...
Closed-loop nanorobot control performance is a key challenge for high-throughput nanohandling. The limited update rate, long latency and unpredictable jitter of tracking based on scanning electron microscope images are a major bottleneck for such closed-loop control. A new approach for high-speed position sensing relying on line scans of a scanning electron microscope is adapted into the control loop...
