Abstract:
Provided is a server for performing a low power communication and an operation method of the server that may generate a packet including collected data based on a maximum number of data items transmitted based on a maximum transmission unit (MTU) established between a client and the server and an allowable delay time of at least one service, and may transmit the generated packet to the client.
Abstract:
A walking assistance method may include: computing an amount of exercise of a user based on a biosignal of the user; adjusting a pattern of an assist parameter based on the amount of exercise; and/or generating a force corresponding to the amount of exercise, based on the adjusted pattern. A walking assistance apparatus may include: a pattern adjuster configured to compute an amount of exercise of a user based on a biosignal of the user; and/or a driver configured to generate a force corresponding to the amount of exercise based on a pattern of an assist parameter based on the amount of exercise.
Abstract:
A wearable robot may include a gear part having an exoskeleton structure to be worn on legs of a user, a sensor part including a first electromyogram (EMG) sensor attached at a first location of at least one leg of the user, and a second EMG sensor attached at a second location, and a controller to detect a walking assist starting point to assist the user with walking, based on a first EMG signal detected by the first EMG sensor and a second EMG signal detected by the second EMG sensor.
Abstract:
Supporting modules, motion assistance apparatuses including the supporting module, and/or methods of controlling the motion assistance apparatus may be disclosed. The supporting module including a supporting member configured to cover at least a portion of a support object, and a sensor module configured to sense information regarding whether the support object is out of a neutral position with respect to the supporting member may be provided.
Abstract:
A data processing architecture includes a processor which may access a memory and fetch a command recorded in the memory, transmit the fetched command to a subject configured to perform an operation corresponding to the fetched command through a network, and receive a result of performing the operation from the subject and record the result of performing the operation in the memory.
Abstract:
A surgical robot includes a console and a manipulator assembly. The manipulator assembly includes at least one arm having a plurality of links and a motor provided between links adjacent to each other among the plurality of links, and a control unit configured to determine whether a mode is changed between a tele-operation mode and a manual mode. The control unit sets output data of the motor provided before the mode is changed as input data of the motor provided after the mode is changed, if it is determined that the mode is changed between the tele-operation mode and the manual mode, thereby preventing the vibration and the rapid change of the posture from occurring at the arm of the surgical robot during the change of the mode between the manual mode and the tele-operation mode, thereby increasing stability of the surgical robot.
Abstract:
An apparatus and method to control a brushless direct current (BLDC) motor, which accurately detect driving current. To this end, the BLDC motor control apparatus includes a BLDC motor, a driver to generate driving current to drive the BLDC motor, a current measurer to measure the driving current, a pulse width modulator to change a driving voltage to drive the BLDG motor; and a controller to control the BLDC motor. The controller detects the amount of the driving current in synchronization with pulse width modulation of the pulse width modulator and determines current with a minimum change due to a variation of counter electromotive force, among currents flowing through a plurality of coils, as the driving current, thereby accurately detecting the driving current.
