Abstract: According to a surgical instrument and a method and device for controlling the posture thereof, a manipulation value according to user input to change a posture of an end tool included in the surgical instrument may be obtained, first posture information about a current posture of the end tool at the time of obtaining the user input may be obtained, and a motion of the end tool based on the manipulation value and the first posture information may be controlled so that a target posture according to the user input is implemented.

Abstract: A method according to an embodiment of the present disclosure includes calculating a first angle difference between a preset reference coordinate system and a first robot base coordinate system, based on a dial manipulation value of a user obtained from a first angle measurement dial mounted on a first robot, calculating a second angle difference between the preset reference coordinate system and a second robot base coordinate system, based on a dial manipulation value of the user obtained from a second angle measurement dial mounted on a second robot, and generating coordinate system transformation information between the first robot base coordinate system and the second robot base coordinate system, based on the first angle difference and the second angle difference.

Abstract: The present disclosure relates to a method and apparatus for driving surgical instruments. The method according to an embodiment of the present disclosure may generate manipulation information related to a user's motion for driving a surgical instrument, calculate first driving information based on the manipulation information, determine the presence of a risk associated with a motion of the surgical instrument based on the first driving information, and drive the surgical instrument based on the result of determining the presence of the risk.

Abstract: A system for processing a read request for maximizing host read performance in a flash memory-based storage device is provided. The system for processing the read request solves a bottleneck phenomenon caused by a processor by adding an independent automatic read request processor, different from a conventional system in which a processor of a storage device processes the read request. Also, when processing the read request, a storage device using a write buffer may control a process of merging data of the write buffer and a flash memory and transmitting the data to a host based on a descriptor array, thereby minimizing processor overhead.
