Nanorobots remain in the realm of science fiction, though robotics is beginning to approach these dimensions. 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 1 mm to 500 mum, we microassemble three dimensional devices that precisely respond to torques...
Advances in both capabilities and miniaturization of medical devices offer promising prospects for medical treatments. Applications range from simple diagnosis to complex treatment tools. Miniature untethered robotic devices are playing a central role within this growing trend, and devices are becoming available on the market. However, one of the biggest challenges is the localization of these devices...
The contact phase of an assembly task involving micro and nano-sized building blocks is complicated by the presence of surface and intermolecular forces such as electrostatic, surface-tension and Van der Waals forces. Assembly strategies must account for the presence of these forces in order to guarantee successful repeatable micro and nanoassembly with high precision. In this paper, a detailed model...
