The present invention relates to a device and a method of detecting arbitrarily piled objects, and a device and a method for picking a detected object. The present invention may provide a device and a method of detecting an object, which extract a unique local characterized part of the object by using a visual sensor, detect an object region, and estimate a posture from the detected object region. Also the present invention may provide an object picking system capable of being applied to an actual production process, such as assembling or packaging, in a cell producing method.

Object picking system, object detecting device, object detecting method

Disclosed is a working method using a sensor, which increases recognition of a component to increase mounting of a component and enhancing productivity. The working method includes: extracting an object to be picked from a pile of objects using the sensor; picking the extracted object to move the picked object to a predetermined place; and estimating an angle of the moved object in the current position using the sensor. Accordingly, the working method can perform precise component recognition and posture estimation by two steps: a component picking step and a component recognition step, and effectively apply to a manufacturing line, thereby improving mounting of a component and enhancing productivity of a product.

An apparatus for performing fault tolerance against a failure occurring during driving robot software components includes: a component executor for executing the robot software components, which are assigned with one thread from an operating system and have a same priority and cycle, by using the assigned thread; and an executor monitor for periodically monitoring the operation of the component executor and determining whether or not there is a failure in the robot software components executed by the component executor. The apparatus further includes: an executor manager for generating the component executor which is assigned with the robot software components having the same priority and cycle and, when the executor monitor determines that there is a failure in the execution of the robot software components, generating a new component executor.

A robot server for controlling a robot, a system for providing content having the same, and a method thereof are provided. The robot server communicating with the robot includes a virtual robot object and a virtual robot object manager. The robot server executes commands that are generated in correspondence to the robot and received from the robot, and controls the robot. The virtual robot object manager generates the virtual robot object corresponding to the robot and activates the virtual robot object when connected to the robot.

Disclosed is a method for data synchronization and update conflict resolution between mobile clients and a server in a mobile system which maintains consistency of data between the clients and the server and enables the clients to continuously perform an effective update operation with respect to objects of the server even in a clients' disconnection state by the mobile clients performing an independent update operation with respect to disjoint fragments and associated objects for a specified object using the structure of the objects and the meaning of applications and then performing the data synchronization and the conflict resolution between the clients and the server during a reconnection operation. The method includes a copy management step of copying data of a server-side DB into a client-side built-in DB and the server managing contents of copying and a copying time, a data synchronization step of synchronizing changed data between the mobile clients and the DB server with respect to a data change produced during the mobile clients' disconnection state in accordance with a request of the mobile clients after a reconnection of the mobile clients, and a conflict detection and resolution step of detecting an error that damages consistency of the data in the data synchronization process and resolving the detected error.

The present invention relates to the fast destaging method using a parity engine, and more particularly to the fast destaging method for constituting and administering the cache of disk array in order to minimize lowering of write performance which occurs in high-speed disk array controller using VRAM parity engine. According to the invention, the disk cache is composed of the read cache, the write cache and the destaging cache. The write caching is processed as being divided into the write cache and the destaging cache. The destaging cache, which has just one more block for mid parity to its data block, uses less memory and enables the write cache to be allocated with more blocks, and thereby it can improve hit ratio of cache. Write requests are first stored on the write cache, and if the write cache is full, they move blocks that would be least used thereafter into the destaging cache. Once destaging is requested, it is practicable with one parity calculation and two write operations by selecting blocks that is least recently used. Also in destaging, block parity calculation can increase its speed and relieve the processor burden by using a VRAM based parity engine which has its dual ports.
