At the University of Karlsruhe, a flexible micromanipulation station based on high-precise piezo-driven microrobots has been developed. Providing a flexible tool in several application fields in the micro world the robots operate either on the stage of an automated light optical microscope or inside the vacuum chamber of a scanning electron microscope (SEM). In order to automate manipulating ta...

This thesis presents on-chip various manipulations of oocyte, in order to improve the controllability of a single cell in the biotechnology, this thesis introduces four different approaches for a single oocyte manipulation. It includes microbeads loading for potential usage of oocytes loading, oocyte enucleation in high-speed with cutting accuracy control, single oocytes dispensing system, and ...

A very wide range of micro-components, such as sensors, mechanical components and actuators can today be produced using micro-techniques. At the current stage, microsystem technology demands for advanced assembly facilities which can assemble complex microsystems consisting of many single components (i.e. hybrid microsystems). To perform a fully automated microassembly, problems specific to the...

Here we present the control, performance and modeling of an untethered electromagnetically actuated magnetic micro-robot. The microrobot, which is composed of neodymium–iron–boron with dimensions 250 m 130 m 10 m, is actuated by a system of six macroscale electromagnets. Periodically varying magnetic fields are used to impose magnetic torques, which induce stick–slip motion in the micro-robot. ...

Insects provide good models for the design and control of mission capable legged robots. We are using intelligent biological inspiration to extract the features important for locomotion from insect neuromechanical designs and implement them into legged robots. Each new model in our series of robots represents an advance in agility, strength, or energy efficiency, which are all important for per...

Our group has recently demonstrated three distinct types of microrobots of progressively smaller size that are wirelessly powered and controlled by magnetic fields. For larger scale microrobots, from 1mm to 500 μm, we microassemble three dimensional devices that precisely respond to torques and forces generated by magnetic fields and field gradients. In the 500 μm to 200 μm range, we have devel...
