In this paper, a visual and haptic human-machine interface is proposed for teleoperated nano scale object interaction and manipulation. Design specifications for a bilateral scaled teleoperation system with slave and master robots, sensors, actuators, and control are discussed. Phantom haptic device is utilized as the master manipulator, and a piezoresistive Atomic Force Microscope probe is sel...
Nanotechnology is an emerging science involving the manipulation of matter on nanometer scale.
We demonstrate a new principle of optical trapping and manipulation increasing more than 1000 times the manipulation distance by harnessing strong thermal forces while suppressing their stochastic nature with optical vortex beams. Our approach expands optical manipulation of particles into a gas media and provides a full control over trapped particles, including the optical transport and pinpoi...
Atomic manipulation enables us to fabricate a unique structure at the atomic scale. So far, many atomic manipulations have been reported on conductive surfaces, mainly at low temperature with scanning tunnelling microscopy, but atomic manipulation on an insulator at room temperature is still a long-standing challenge. Here we present a systematic atomic manipulation on an insulating surface by ...
Dexterous robotic manipulation refers to the coordination of multiple fingers or manipulators grasp and manipulate a target object. In past decades, various achievements have been established in dexterous physical world. However, such ability is rarely found nano/micro manipulation, which mainly due difficulty developing actuators sensors at nano/micro-scale, as well dependence on properties ob...
Advances in electron microscopy have revolutionized atomic-scale imaging, characterization, and manipulation of materials.
We consider three important, non-strategyproof assignment mechanisms: Probabilistic Serial and two variants of the Boston mechanism. Under each of these mechanisms, we study the agent’s manipulation problem of determining a best response, i.e., a report that maximizes the agent’s expected utility. In particular, we consider local manipulation strategies, which are simple heuristics based on loc...
This paper develops a novel approach to microscale locomotion and manipulation using flagellated bacteria for actuation. We use a blotting procedure to attach flagellated bacteria to a buoyancy-neutral plate called a microbarge and deploy the plate in a microchannel . The motion of the plate depends on the propulsion of the bacteria which in turn depends on the distribution of the cells on the ...
