Abstract:
PURPOSE: A remote control system for managing a remotely operated robot under multiple frequency environment and a remote control method are provided to perform a current mission regardless of a frequency change by a remote robot when a communication frequency is changed by moving the remote robot to the other FAs(Frequency Area). CONSTITUTION: A remote control system(200) comprises base stations(102/1,102/2), a base station management unit(204), and a remote operation device(2000). Two or more robots(101,102) are connected to the base stations using multiple FAs. The base station management unit receives and updates a total communication traffic and present communication bandwidth of the base stations and changes the frequency band of the remote robot after saving task information and state information of the remote robot when the change of the frequency band of the remote robot is request. The remote operation device manages the base station management after saving the task information and state information of the remote robot and changing the frequency band of the base station management unit so that the task information and state information is recovered.

PURPOSE: A system and a method for the integral operation of an unmanned robot are provided to perform an adaptive and effective task by performing collaboration through integration control based on sharing tasks and hierarchical authorization. CONSTITUTION: An RMS(Remote Mission Station)(110) provides the operational aurthorization of an unmanned robot per ROS by allocating unmanned robots(310,320) and tasks to perform per ROS(Remote Operation Station)s(210,220). The ROS selectively operates the allocated unmanned robots and controls the operation about the allocated unmanned robots. A wireless transceiving unit performs as a remote task device, the ROS, and communication between the unmanned robots. The remote task device classifies a function which is controllable to an unshared and shared task. The shared task gives temporary control rights to other ROSs which have not received the operational authorization.
Abstract:
PURPOSE: An apparatus for generating a grid map and a method thereof is provided to calculate travel costs at the grid of a grid map by collecting layer information and property and processing it. CONSTITUTION: In an apparatus for generating a grid map and a method thereof, a layer / property aggregation module(100) collects layer information related to traveling and property information. A traveling costs extraction module(200) converts layer information and property information into traveling costs. A multiple layer traveling combination module(300) determines final traveling costs at grid. A traveling speed mapping module(400) confirms seed corresponding to final traveling costs.
Abstract:
Provided is an unmanned autonomous vehicle according to the present invention to which an autonomous running method in a dynamic environment is applied, wherein the autonomous running method comprises extracting a grid (Nbest) having the lowest assessment function value from an open list and surveying a probabilistic threat degree of the corresponding grid by a moving obstacle; recalculating the assessment function value of the Nbest if no threat degree has existed when the Nbest was inserted into the open list and the threat degree exists at this point in time due to the movement of the obstacle; recalculating the assessment function value for a grid having the thread degree among neighboring grids that have been previously detected or existed as candidates when performing an extension task of inserting the neighboring grids of the Nbest into the open list for route detection; recalculating the assessment function value for child grids of the neighboring grids using this, thereby, if a grid, where no threat degree of the obstacle has existed at the previous point in time, has a new threat degree by a movement of a moving obstacle at this point in time, performing a local route plan for the autonomous running of the unmanned vehicle by reflecting information like this.
