Abstract

PROBLEM TO BE SOLVED: To keep a toy main body from falling down by putting the toy main body in an erect attitude in a plate-like narrow tooth provided on the lower part thereof, detecting inclination of the toy main body by an inclination detecting sensor, and controlling the rotating direction and the rotating speed of a motor for correcting the inclination to generate reaction couple. SOLUTION: A body 1 forming a toy main body is grounded at a plate-like narrow tooth 4 provided on the lower part thereof on the floor surface. A rotor 2 provided with an outer peripheral ring 3 is supported on the body 1 in such a manner that the rotation of a motor incorporated in the body 1 is decelerated by a gear train and transmitted to the rotor 2 to be rotated. An inclination detecting sensor is adapted to detect the reflection return light quantity from the floor surface of light from a light emitting element 5. The sensor is fitted to one side of the body 1. According to an inclination detected by the inclination detecting sensor, a motor 8 is driven through a control circuit, and the rotating speed of the rotor 8 is increased in the opposite direction to the direction for correcting the inclination to generate reaction couple, thereby keeping the erect attitude.

Since the body 1 has a single thin plate-shaped tooth 4 that is in contact with the floor, the body 1 may fall to the left or right unless controlled. The rotating body 2 has an outer peripheral ring 3 to increase the moment of inertia. In order to increase the driving torque of the rotating body 2, the rotation of the motor 8 is reduced by the gears 9a and 9b, and then the rotating body 2 is rotated by the shaft 10 of the rotating body.

Is to prevent it from falling down and being damaged.
The tilt detection sensor is attached to one side of the body,
The light receiving element 6 detects the amount of light returning from the floor surface of the light from the light emitting element 5. The light emitting element 5 is an infrared light emitting diode,
The light receiving element 6 uses an infrared phototransistor.
The amount of light received by the light receiving element 6 increases when the body 1 tilts and the distance from the floor surface decreases, and decreases when the body 1 separates. Therefore, the inclination can be detected by taking the difference using the amount of received light in a straight standing state as a standard value. The inclination detected by the inclination detection sensor is input to the control circuit 7, and the control circuit 7 drives the motor 8 to increase the rotation speed of the rotating body in a direction opposite to the direction in which the inclination is to be corrected, thereby generating a reaction couple. And resilience.

FIG. 4 is a block diagram showing the flow of control. The sensor amplifier amplifies the signal from the tilt detection sensor and adjusts the offset and the gain by using a variable resistor, and outputs the analog signal to the arithmetic circuit. The arithmetic circuit uses PI from the signal from the sensor amplifier.
An operation such as D control is performed, and an analog amount is output to the PWM circuit. This function sets the offset so that the received light amount at this time is set to a zero point with no inclination, assuming that it is placed in a state of standing upright when the start button is pressed. The PWM circuit outputs a forward rotation pulse and a reverse rotation pulse pulse-width-modulated at regular intervals according to an analog amount from an arithmetic circuit capable of performing inverted control in response to the motor amplifier. The forward rotation pulse and the reverse rotation pulse specify the rotation direction of the motor, so that only one of them is not transmitted simultaneously. The motor amplifier drives the motor by amplifying the current of the forward rotation pulse or the reverse rotation pulse as it is, and switches the polarity so that the motor rotates forward in the case of the forward rotation pulse and reverses the motor in the case of the reverse rotation pulse. The control circuit 7 includes the sensor amplifier, the arithmetic circuit, the PWM circuit, and the motor amplifier of this block. In this embodiment, the arithmetic circuit and the PWM circuit are ordinary analog circuits, but this function can be performed by an AD converter and a microcomputer.

Since the mechanical effect of the rotating motion of the rotating body 2 depends on a change in the number of revolutions, the object of motor control is originally a change in the number of revolutions. In this embodiment, however, the number of revolutions of the motor 8 is detected. First, the flow of information is configured such that the pulse width is unilaterally set and the motor 8 is simply turned. Experiments on prototypes have confirmed that this control method can maintain a sufficiently stable inverted state.

In addition, a gyro sensor is usually used to detect the inclination. In this embodiment, since the light emitting element 5 and the light receiving element 6 are used, this also leads to a reduction in cost. Since the movement is larger than the control based on the position of the actuator, the toy is interesting.
