To achieve the skillful task like the human, many researchers have been working on robot hand. An interaction with vision and tactile information are indispensable for realization of skillful tasks. In the existing research, the method using a camera to get the vision information is often found. But, in the boundary area of a non-contact phase and a contact phase, there are problem that lack of sensor information because the influence of occlusion comes up to surface. We devise to introduce the proximity sensor in this area. And we call the robot hand which is equipped with proximity, tactile and slip sensor "intelligent robot hand".In this research, we show the constitution example of the intelligent robot hand and propose the method to realize Pick&Place as concrete task.
Microbubbles are very small bubbles with a diameter of 50 m or less. The important characteristics of microbubbles are their large specific area and small buoyancy, and therefore effective dissolution of gas phase and high adsorption rate are expected. The utilization of microbubbles is useful in improving water environments. Research efforts at a number of institutions have been devoted to the development of microbubble generators. However, in previous microbubble generation devices, complex mechanisms and a high power supply have been required. In this study, a compact and low-power microbubble generator has been developed. Microbubbles were generated by inducing local shear stress in the flow of water through a pipe with slits. Three types of model (slit angle = 30 • , 60 • , and 90 • ) were used in order to investigate the effect of slit angle on the purification technique. The proposed microbubble generator with the slit angle = 60 • showed superior performance for the water purification technique in comparison with the other two models. It was confirmed that microbubble generation was affected by slit angle. Also, in this study, we investigated the electrical property of the gas-water interface, and the -potential of microbubbles was measured by electrophoresis. The results of the floatation experiments were affected by the -potential of the microbubbles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
