Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an operation apparatus having a flexible operation,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device, and more particularly, to an operating device having a flexible operation for performing an intuitive operation and a control method thereof.

The arm of the person can be turned up and down, right and left, forward and backward, and can be rotated at arbitrary positions whirled up and down, right and left, and back and forth. Arms with this function are very easy to use in delicate manipulations, for example when drawing, painting, bolting, or performing welding tasks.

In particular, a manipulator refers to an application of an industrial robot with a function similar to a human arm, and is used in a dangerous area or an area requiring remote operation.

The manipulation of the conventional manipulator was based on the screen of the simple imaging device to determine the surrounding situation. As a result, the user is required to perform repetitive learning and thus a lot of fatigue is required for the operation. In addition, there is an increasing demand for precise and difficult work, rather than a simple work, but the operation mechanism or the methodology capable of coping with it is insufficient, so that the work can not be smoothly performed.

Therefore, there is a need for a manipulation mechanism or methodology that can easily perform a precise and difficult task in the remote control of the manipulator.

In the drawings, the same reference numerals as used in the appended drawings denote like elements, unless indicated otherwise. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather obvious or understandable to those skilled in the art.

1 is a block diagram for explaining an operating device according to an embodiment of the present invention.

Referring to Fig. 1, the operating device 100 performs automatic coordinate conversion so that the manipulator 10 can be intuitively manipulated. The manipulation device 100 enables manipulation of a manipulator (not shown) that is precise even with remote control and has a high degree of difficulty. Here, the intuitive manipulation means that the manipulator performs the manipulation in the direction in which it is manipulated by the manipulator. That is, the intuitive manipulation means that the manipulator moves according to the movement of the manipulator even when the manipulator and the manipulator are positioned at different points in time. The operation device 100 includes an operation device 10, a communication section 20, a sensor section 30, a control section 40, a motor section 50 and a storage section 60.

The manipulator 10 remotely controls the manipulator. The manipulator 10 generates an manipulation signal for remotely manipulating the manipulator. The operation unit 10 can operate at least one of X-axis movement, Y-axis movement, Z-axis movement, and rotational movement.

The communication unit 20 receives the position information of the manipulator and transmits an operation signal generated from the manipulator 10. Here, the position information of the manipulator is information on the current position and viewpoint of the manipulator. In particular, the position information of the manipulator can be displayed in three axes (X axis, Y axis, Z axis) coordinates. The communication unit 10 may perform wired communication or wireless communication, and may preferably perform short-range wireless communication.

The sensor unit 30 measures the position information of the manipulator 10. Here, the positional information of the manipulating device 10 may be information on the current position and viewpoint of the manipulating device 10, and may be displayed in three-axis coordinates. The sensor unit 30 may be provided in the actuator 10, specifically, at a position adjacent to the center of the actuator 10. The sensor unit 20 may include sensors such as a linear sensor, a gyro sensor, a tilt sensor, an acceleration sensor, and the like.

The control unit 40 performs coordinate conversion on the position information of the manipulator received from the communication unit 20 on the same axis as the position information of the manipulator 10 measured by the sensor unit 30. [ At this time, the control unit 40 can perform coordinate transformation using the Euler Angle. Here, the Euler angles can be expressed by a matrix and are expressed by the following matrix.

[Determinant]

Here, RPY (陸, 慮, Ψ) denotes coordinates on the X axis, Y axis and Z axis, Φ denotes the angle of the X axis, θ denotes the angle of the Y axis, And a, o, n mean constants.

Accordingly, the control unit 40 performs coordinate transformation so that the axial direction of the position information of the manipulator is the same as the axial direction of the position information of the manipulator through the determinant.

For example, when the position information of the manipulator and the position information of the manipulator are the same in the Y axis direction and the Z axis direction, the X axis direction of the position information of the manipulator is 12 o'clock direction, and the X axis direction of the position information of the manipulator is 9 o'clock , A difference of 90 [deg.] With respect to the X-axis occurs. In order to eliminate such difference in the axial direction, the controller 40 applies the Euler angles to the position information of the manipulator to coordinate the X-axis from the 12 o'clock position to the 9 o'clock position to make the axial directions the same.

The control unit (40) remotely adjusts the manipulator by applying the manipulation signal generated from the manipulator (10) to the position information of the manipulated manipulator.

In addition, the controller 40 can adjust the position of the controller 10 according to the state of the user. The control unit 40 can move the body supporting the manipulator 10 in the X-axis, the Y-axis, and the Z-axis, and the three-axis movement can be controlled by a motor. Here, the main body will be described in detail with reference to FIG. 2 to FIG.

The motor unit 50 controls the motor in accordance with the motor control signal generated by the control unit 40. The motor unit 50 includes at least three motors, and each of the three motors can perform X-axis movement, Y-axis movement, and Z-axis movement, respectively.

The storage unit 60 stores a coordinate transformation algorithm. Also, the storage unit 60 may store a default setting value (default) capable of calibrating the manipulator.

Here, when the operating device 100 is not operated for a predetermined time, the promotional device 100 may transmit the basic setting value stored in the storage portion 60 to the manipulator so that the manipulator can be automatically calibrated.

The conveying support portion 83 is formed with a connecting member to be connected to the first Y-axis guide rail 86 and the second Y-axis guide rail 87 at a lower portion thereof. Accordingly, the conveying support portion 83 can move the operation device 10 along the first Y-axis guide rail 86 and the second Y-axis guide rail 87. Here, the conveyance support part 83 may be connected to the motor part 50 and may be moved in accordance with the motor control of the control part 40.

The fixing part 84 is formed in a bolt shape at the end of the conveying supporting part 83 to fix the conveying supporting part 83 which has been moved. That is, the fixing portion 84 fixes the movement of the conveying support portion 83 by inserting a bolt in the through-hole 85 formed in the supporting portion 81. Here, the fixing portion 84 can facilitate the movement of the conveying support 83 by separating the bolt shape from the through-hole 85 when the conveying support 83 is moved.
