In micromanipulation, lots of methods have been developed to manipulate objects in microscale. However, few of them can be applied in both the transportation and the rotation of the micro objects. In this paper, we present a novel method to realize the non-contact transportation and rotation of the micro objects based on the vibration-induced swirl flow. A piezo actuator is set between the glass needle...
Micromanipulation provides researchers a new way to fabricate complex structures through assembling small components, and it is also a useful tool for single cell manipulation. Many micromanipulation methods have been proposed, but only the few are capable of rotation of the micro targets. In this paper, we present a simple non-contact high-speed rotation method based on the local flow generated by...
Shock and vibration from the rocket launch brought high demands for the design of space robot. This article describes the simulation and design optimization on a six degree of freedom space manipulator we had designed for space robot. Firstly, the article describes the configuration design, Denavit-Hartenberg parameters, and so on. Then, based on the mechanical requirements of rocket to payload, mechanical...
The simulation of space microgravity environment is indispensable during the development of space robot since its performances should be examined and enhanced before sent into space. However, the existing methods, such as air flotation method, hanging wire method and buoyancy method, etc., are very expensive and complex. A low-cost microgravity simulating system is proposed in this paper. In this...
A gyroscope based on Coriolis effect and fabricated by Carbon Nanotube (CNT) was presented. The gyroscope was designed A CNT is vibration at x direction, when there a rotation around z direction, acceleration happens to the y direction. The natural frequency of MWCNT is depending on the inner diameter, outer diameter and length. The CNT was driven by the electrostatic force to its nature frequency...
