Virtual Landmark-Based Control of Docking Support for Assistive Mobility Devices

This work proposes an autonomous docking control for nonholonomic constrained mobile robots and applies it to an intelligent mobility device or wheelchair for assisting the user in approaching resting furniture such as a chair or a bed. We defined a virtua ...

Probing the Morphology and Evolving Dynamics of 3D Printed Nanostructures Using High-Speed Atomic Force Microscopy

Georg Fantner, Maja Dukic Pjanic, Chen Yang, Jie Zhao

Focused electron beam induced deposition (FEBID) has been demonstrated as a promising solution for synthesizing truly three-dimensional (3D) nanostructures. However, the lack of morphological feedback during growth complicates further development toward hi ...

Digitally controlled analog proportional-integral-derivative (PID) controller for high-speed scanning probe microscopy

Georg Fantner, Nahid Hosseini, Adrian Pascal Nievergelt, Maja Dukic Pjanic, Santiago Harald Andany, Chen Yang

Nearly all scanning probe microscopes (SPMs) contain a feedback controller, which is used to move the scanner in the direction of the z-axis in order to maintain a constant setpoint based on the tip-sample interaction. The most frequently used feedback con ...

Design of a high-bandwidth tripod scanner for high speed atomic force microscopy

Georg Fantner, Nahid Hosseini, Maja Dukic Pjanic, Chen Yang, Jie Zhao

Tip-scanning high-speed atomic force microscopes (HS-AFMs) have several advantages over their sample-scanning counterparts. Firstly, they can be used on samples of almost arbitrary size since the high imaging bandwidth of the system is immune to the added ...
