In this paper we propose a new infrastructure of storage overlay networks (SONs) that connect several distributed Internet nodes into an overlay network to provide in-network, aggregated storage. A SON node can encode, recode, and decode data on purpose. The SON improves information availability and security with erasure coding, and improves network efficiency by re-encoding received information....

The recent increase in technological maturity has empowered robots to assist humans and provide daily services. Voice command usually appears as a popular human–machine interface for communication. Unfortunately, deaf people cannot exchange information from robots through vocal modalities. To interact with deaf people effectively and intuitively, it is desired that robots, especially humanoids, have...

Collision avoidance is essential for safe robot manipulation. Especially with humans around, robots should work only when safety can be robustly guaranteed. In this paper, we propose using virtual impedance control for reactive, smooth, and consistent collision avoidance that interferes minimally with the original task. The virtual impedance control operates in the risk space, a vector space describing...

Remote diagnosis systems can improve internet technology by monitoring the equipment status; it increases availability of production and facility equipment, reduces Mean Time to Repair (MTTR), and depletes field service resources and costs. In this paper, we propose a prototype of remote diagnosis system with UML and data mining technique—support vector machine. We adopt UML to model and design the...

Robust visual servoing is still a difficult problem for a robotic arm system. Within the computer vision community, many object recognition and localization systems have been developed, but in general, they are not tailored to robotic arm applications. In particular, accurate object detection and localization in the camera coordinate system is crucial for grasping. In this paper, we will present a...

This paper provides an intuitive way to inference the space of a scene using stereo cameras. We first segmented the ground out of the image by adaptively learning the ground model in the image. We then used the convex hull to approximate the scene space. Objects within the scene can also be detected with the stereo cameras. Finally, we organized the scene space and the objects within the scene into...
