Various stunts performed by MURATA BOY

The robot is on a bicycle. It maintains its balance even when fully stopped!
Performs stunts such as climbing slopes and running on balance beams.

POINT01
Coming to a stop and maintaining his balance

Doesn’t totter and maintains his balance!
He is capable of standing straight even when the bicycle has stopped.

POINT02
Obstacle detection

With his ultrasonic sensor, he is capable of stopping before running into obstacles.

POINT03
Incline climbing

Climbs steep 25-degree slopes with ease and can climb them without a running start.

POINT04
Balance beam run

Crosses 2 cm wide balance beams with ease.
He is capable of clearing it without falling over.

POINT05
Running in reverse

He is capable of running without falling over. And he doesn’t even have to look backwards.

POINT06
Runs over an S-curve balance beam

Witness his excellent driving technique. Watch him enter a curve while maintaining his balance.

MURATA BOY's Components

Information about MURATA BOY's components.

  • Gyro Sensor

    The gyro sensor detects minute slanting angles or turning motions of the body. 
    Makes free standing and super-slow runs possible.

  • Ultrasonic sensor

    Measures the distance to objects by transmitting ultrasonic waves and calculating how long it takes the waves to bounce back. Detects obstacles to avoid collision.

  • Shock sensor

    Sensor for detecting vibration and shock. Used in a range of applications from PC hard disks to automotive airbag systems. Detects bumps and unevenness in the road.

  • Bluetooth® modules

    One-chip functionality for wireless sending and receiving control signals and sensor data.

  • Filter

    Extracts only the necessary signal, filtering out unwanted noise. Filters out interference to ensure stable operation.

  • Power Supply Module(DC-DC Converter)

    Exchange the power voltage efficiently with the one battery.

  • Timing Device

    Creates a reference signal for operation of the microcontroller.

  • Capacitor

    Able to charge and discharge electricity repeatedly, capacitors are widely used for tasks such as stabilizing microcontrollers or power supplies, or extracting constant-frequency signals.

  • Inductor

    Stabilizes electric current and signals in wireless communication circuits and power supply circuits.

  • NTC Thermistor

    Monitors the temperature of ICs, power supply circuits, and batteries to protect the circuits from excessive current and overheating.

Q&A
MURATA BOY’s secret

Q.He is capable of standing straight even when the bicycle has stopped.
Why doesn’t he fall over?

A.His secret lies in the gyro sensor that is installed underneath the saddle.

Gyro sensors are capable of detecting the bicycle’s slightest tilt. A force that recovers the tilting occurs by rotating the disk located in MURATA BOY’s chest when tilting of the bicycle is detected. Repeating this enables MURATA BOY to maintain his balance and posture.

Q.With an ultrasonic sensor, is capable of stopping before running into obstacles.
Why doesn’t he crash?

A.The secret lies in the ultrasonic sensor.

The distance to the obstacle is measured with ultrasonic waves, enabling him to stop immediately before crashing.
