BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spoon having a horizontal holding function, and more particularly, to a spoon having a horizontal holding function for detecting rotational motion of a spoon and compensating the same.

Referring to Fig. 1, the operation of the conventional rotating spoon will be described.

The conventional spinning spoon shown in FIG. 1 is a 'LiftWare spoon' from 'Lift Labs', and a technique of 'vibration cancellation' is applied in which a motion generated by a user is read, a motor in the device is operated, and motion is canceled. This minimizes tremor at the end of the sprocket.

The conventional technique is a technique for preventing shaking of the user's hand by using the principle of vibration cancellation, or prevention of leakage of food even if the arm is shaken. The object of this technique is to prevent simple hand tremor in patients with Parkinson's disease. The range of movement of the handle is not different from that of ordinary spoon. For example, if you put a spoon in the presence of food, the food will fall off. Therefore, there is a problem that the subject using this product is limited to the hand tremor patient who can smoothly control the spoon.

In addition, this technique has a limitation in that it can be rotated only in the wrist direction of the handle, so that there is a problem that accurate control of the food can not be performed when changing the inclination to another axis. In addition, since it is impossible to fix the head part according to the case, there is a problem due to the rotation of the head part when the food is spread with the spoon.

Accordingly, it is urgently required to develop a spoon having a horizontal holding function capable of detecting a shake or movement in various directions of a spoon held by a user during a meal and automatically compensating the spoon to maintain a horizontal state.

The present invention seeks to provide a spoon having a horizontal holding function that allows the spoon to keep horizontal even if the user's hand is shaking during meals.

On the other hand, the head and the body may be detachably connected.

Meanwhile, a fixing button for fixing the movement of the head part may be formed on the body part.

The measuring unit may include an angular velocity sensor for measuring an angular velocity of the body and an acceleration sensor for measuring an acceleration of the body.

Meanwhile, the rotating means may include a first motor for rotating the head portion by a roll shaft, and a second motor for rotating the head portion by a pitch axis.

Meanwhile, a charging port for charging the battery through an external power source may be formed on one side of the body portion.

According to an embodiment of the present invention, a spoon having a horizontal function includes measuring means and rotating means. The measuring means can sense the movement of the spoon and compensate it in real time by means of the rotating means. Accordingly, even if the user's hand shakes during eating, the head of the spoon can be kept horizontal, so that the meal can be stably performed.

 First, when the spoon body 120 is tilted, the measurement means 200 incorporated in the body 120 senses this and transmits the tilt value sensed by the arduino in the form of a signal. The signal is converted to a digital value via the ADC built into the ADC, and the reliability can be improved by going through the compensation filter.

 Thereafter, a driving signal is sent to the rotating means 300 as much as the initial value set in the horizontal direction of the head 110 in the arduino. The head unit 110 operates through the driving signal of the rotation unit 300 that receives the driving signal and controls the head unit 110 to maintain the slope of the initial value designated by the user so that the head unit 110 can maintain the horizontal state.
