One Wheel

Figure: Overview of a OneWheel.    

HOW IT WORKS

• Step on the platform with your trailing leg. Then, place your front foot on the blue section of the front to engage the sensors.

• Lean forward and allow the board's electronic controllers to take control. The more you lean, the faster you'll go.

• The OneWheel uses a combination of sensors to monitor your motion and provide the correct voltage to the direct drive hub motor.

• When you finish riding, simply break contact with the front sensor and dismount the board.

SPECS

SENSORS

HALL EFFECT SENSOR

This sensor measures output voltage as response to a magnetic field for determining positioning, speed and current sensing applications.

PROPORTIONAL-INTEGRAL-DERIVATIVE (PID)

Control loop feedback mechanism that continuously calculates an error value as the difference between a desired setpoint and a measured process variable and applies a correction based on a proportional, integral, and derivative term.

ACCELEROMETER

A sensor used for measuring long-term, low- frequency acceleration.

RATE GYROSCOPE

Indicates the rate of change of angle with time for short-term, high-frequency applications.
