Abstract:
A method for modeling a user intention based on human desire and a system thereof are provided to offer efficient, active and intelligent services in a ubiquitous environment by supporting provision of services where various user's intentions are reflected. A system for modeling a user intention based on human desire includes plural user intention model servers(410), plural ontology servers(420), a service providing device(430), a status information collector(440), and a remote machine(460). Each of user intention model servers is composed of a Bayesian network, includes a user intention model(412) for expressing a user's intention and a Bayesian network inference engine software(414) for analyzing the user intention model. Each of ontology servers includes an ontology(422) for describing the user's intention model, and an ontology inference engine software for inferring the user's intention by using the ontology and external input information. The user's intention can be used via the service providing device like a robot(432) or an agent(434). The remote machine is used for additionally extending the user's intention at a remote place.
Abstract:
A network-based robot control system in a dynamic IP address environment is provided to construct and operate a robot control server in a DHCP(Dynamic Host Configuration Protocol) environment as well as in a shared network environment so that a user can easily construct a PC-based robot control server at home. A network-based robot control system in a dynamic IP address environment consists of a robot(700), a robot control server(500), and an authentication server(100). The robot makes an authentication request for network access, and executes network access, based on a packet received according to an authentication result. The robot control server creates a virtual robot object for the robot, stores and manages information for the robot's network access, and executes an operation corresponding to a command received from the robot connected to a network. The authentication server authenticates, registers, and manages information about the robot control server which performs network access with the robot. If an authentication request packet is received from the robot, the authentication server transmits a response packet, and issues an authentication key for the robot control server. Using the authentication key, the authentication server checks an authentication result for the robot control server. Also, using the authentication key, the authentication server allocates and distributes the robot control server the robot will access.
Abstract:
A method for radio sensor network communication by using infrared rays and RF communication and an apparatus therefor are provided to perform selectively infrared communication and RF communication for low power consumption, thereby realizing the RF sensor network communication with low power than performing communication with only an RF communication function. A first communication unit wakes up a neighbor node in a standby status through an infrared signal and transceives sensor data with the waked node. A second communication unit transceives the sensor data with the waked neighbor node through an RF(Radio Frequency) signal. A radio node processing unit(110) wakes up from the standby status if the wake-up signal of the infrared signal is received through the first communication unit, wakes up the neighbor node in the standby status through the first communication unit in order to transmit the received sensor data to a target node if the sensor data is received through one of the first and second communication units, and transmits the sensor data with the minimum power consumption through one of the first and second communication units.
Abstract:
A system and a method for generating BPEL4WS using OWL-S and a web service are provided to offer various services and apply to a robot platform having different service interface by mapping a process model and I/O(Input/Output) message information defined in the OWL-S to the process model defined in the BPEL4WS, and enabling WSDL(Web Service Description Language) to generate the BPEL4WS from the outside of the robot platform. A service plan analyzer(110) extracts a WSDL document describing a web service by receiving an OWL-S base service plan instance and analyzes an OWL-S base service process structure. A WSDL analyzer(120) analyzes the extracted WSDL document. A process model mapper(130) maps the process model of the BPEL4WS and the OWL-S by receiving an analysis result from the service plan analyzer and the WSDL analyzer. A process model generator(140) generates a BPEL4WS model on a memory by using a mapping rule output from the process model mapper. A file converter(150) converts and outputs the BPEL4WS model in a file form.

Abstract:
Service robot developers and application programmers have produced a service application in a manner of directly controlling hardware, and this causes limitations on the reusability of the service application and the expandability of a service robot market as wells as the overall change in the service application whenever the hardware is changed. According to an embodiment of the present invention, provided is an apparatus for a human-robot interaction service, which can be reused without wasting resources, such as time, money, and manpower, by integrating various sensors and hardware (actuators) in a service robot and maintaining compatibility such that service application developers can develop an application in unified standards. Furthermore, the present invention provides an apparatus for a human-robot interaction service, which can promote the reusability of components and improve the efficiency of service application and component development by proposing a unified interface between the components of a service robot technique and the application program, for the service robot market.
