Localized Rotation for 3D Visual Reconstruction

A variety of different methods exist for gathering three-dimensional information for micro- and nanoscale objects in an electron microscope. We apply structure-from-motion techniques as efficient, high-precision alternatives to traditional stereo methods which allow for automated utilization of a large number of sampled images. Using helical nanobelts to generate localized rotational motions quickly provides large data sets with frequent measurements, alleviates the demand of high-precision actuators, allows 360 degree rotations, and provides a useful tool for micro- and nanomanipulation.

Rigid Body Tracking for Nanomanipulation and Characterization

Real-time visual feedback from electron microscopes are typically noisy and pose significant challenges to an image processing system. This work proposes using rigid model based algorithms for object tracking in a scanning electron microscope. The use of domain specific knowledge by the introduction of two- or three-dimensional object models can be used to provide extra information to the tracking process and increase the system precision.

NEMS Based on Individual CNT-Based Nanostructures

Linear servomotors play a significant role because they provide precision prismatic motion directly without requiring a conversion from rotary to linear motion which generally decreases efficiency and results in a larger and more complex mechanism. More Information...

Visualization and Tracking of Nanostructures in Aqueous Environments

Undoubtedly one of the most promising fields of application for nanorobotics are biomedical tasks in a biological environment. While we do have a track record in nanomanipulation and assembly in high-vacuum, the environment in a biological cell or the human body is aqueous and has thus very different requirements. This work aims at optical tracking of devices the visualisation of morphological changes in such conditions. More Information...
