CONSTITUTION: A wire power transmission device comprises a first rotating body(121) rotating by power input; a second rotating body(125) connected to a rotating shaft(141) of the first rotating body and fixed to a rotating shaft(145) rotating relatively to the first rotating body; third rotating bodies(123a,123b) to which wires(131,132) wound around the first and second rotating bodies are connected; and rotating frames(115L,115R) connecting the rotating shafts and the third rotating bodies to make the third rotating bodies revolve around the rotating shaft of the first rotating body and the rotating shaft of the second rotating body. The third rotating bodies transmit the rotational speed of the first rotating body to all over the second rotating body through acceleration and deceleration. One of the wire connecting the first and third rotating bodies and the wire connecting the second and third rotating bodies is connected by a crosswise hanging method and the other is connected by a rightly hanging method.

PURPOSE: An apparatus for calibrating and fixing a three-dimensional position of a medical operation device is provided to perform simultaneously a fixing operation and a measuring operation by improving a structure of the medical operation device. CONSTITUTION: An apparatus for calibrating and fixing a three-dimensional position of a medical operation device includes a link portion of a multi-degree of freedom, a balance portion, a module portion, a distributive control portion, an electric brake portion, two or more fixing pins and a pin hole portion. The link portion(101) of a multi-degree of freedom includes a plurality of rotary joints. The link portion(101) is connected to a control area network through a PC. The balance portion compensates the movement and the weight of the link portion(101) by adding weights and springs to each joint. The module portion is formed by unifying a controller, a position sensor, and a fixing portion. The distributive control portion is formed with a distributive controller and a main controller. The electric brake portion is controlled by an external switch or a program. The fixing pins are combined with the pin hole portion.

PURPOSE: A system and a method for controlling a motor miniaturized by using an integrated motor unit are provided to reduce the dimension of a motor control system by integrating boards for controlling a motor control system and connecting to a network. CONSTITUTION: A motor(111) is surrounded by a housing. A cord wheel(112) detects a rotatory state of the motor(111). A motor control board(120) drives the motor(111) according to a control signal and generates rotatory state data with respect to the motor(111). A network board(130) abstracts the control signal with respect to the motor(111) from communication data transmitted from a central controller(200) to transmit it to the motor control board(120) and receives the rotatory state data of the motor(111) from the motor control board(120) to transmit it to the central controller(200). A connector board(140) connects the motor control board(120) and the network board(130) to the central controller(200) through a network.
Abstract:
PURPOSE: A device for generating vibration and method for changing the path of a robot are provided to reduce rubfriction and to change the path of the robot motion by a robot controller at assembling. CONSTITUTION: Plural piezo actuators(11,12) are fixed in a robot flange mounting section(10). A fixing plate(13) is installed between piezo-actuators and integrated with a robot flange section. A tool installation section(17) is installed in the fixing plate by a pivot section and edge sections of the tool installation section are contacted with ends of piezo actuators. A control unit regulates expansion and contraction of piezo actuators. The control unit drives piezo actuators and shifts position of edge sections in the tool installation section. Rub friction of products is reduced by the rotation at assembling, and the path of the robot is changed according to the signal processing of a robot control unit. The vibration generating device and the robot path shift method are useful to assemble components accurately.

The calibration can measure the variation amount in lengths of the arms of robot occurring from the temperature variation around by comparing the calibration jig which is dull with the temperature variation with the initially set value by measuring relatively at the indicated measuring plant with using a non-contact sensor.
Abstract:
A high speed precision measurement arrangement for three- dimensional rectangular coordinates contains gentry type servo- pneunatic pressure drive modules for the X, Y and Z axes using CNC linear drive axes. CNC controllers control the drive motors of the three axes. A process computer transmits and receives the data to and from the CNC controllers and a contactless laser-optical measurement probe is attahced to the base of the Z axis drive module to measure the distance to the surface of a measurement object.

PURPOSE: A cognitive ability training apparatus using a robot and a cognitive ability evaluation method thereof are provided to give a cognitive treatment in a three-dimensional real space by delivering instruction through a robot and perform various cognitive treatments utilizing the whole body of a patient. CONSTITUTION: A cognitive ability training apparatus(100) includes an instruction generating unit(110), a sensor unit(120), a trainee action information generating unit(140), and a cognitive ability determining unit(150). The instruction generating unit generates a series of robot instruction information to indicate the action of a robot and a series of trainee instruction information to indicate the action of a trainee. The sensor unit copies the action of the robot following the robot instruction information or collects sensor information including three-dimensional location information, color information, or mobile device usage information of the trainee action following the trainee instruction information. The trainee action information generating unit generates trainee action information based on sensor information collected by the sensor unit. The cognitive ability determining unit determines the cognitive ability of the trainee based on the robot instruction information, the trainee instruction information, and the trainee action information.
