Objectives

• Build a one wheel skateboard that balances
  itself.
• Forward and reverse capabilities.
• Control the speed and the direction of the
  skateboard by shifting your weight forward or
  backward
• Learn more about various electrical components
• Programming of microcontroller

3
Steps

• Design the skateboard and identify the needs,
  both electrical and mechanical.
• Understand how the OSMC motor controller works.
• Understanding how the Arduino works.
• Programming how to acquires different inputs
  from sensor, how to treat the inputs to get the
  desirable outputs.
• Building the board itself
• Testing and calibration

4
Accomplishments (so far)

• Identified needed components to acheive our goal.
• Understanding the functionnality of the Open
  Source Motor Controller and microcontroller.
• Programming the arduino board.
• Make the motor reacts with the change of angles
  given by the accelerometer.
• Implementing safety measures.

Electrical components

• OSMC control the motor power and direction
• Arduino control the OSCM and motor speed
• Gyroscope convert physical signal to analog
• Motor 24V,ungeared DC motor, 4000rpmapprox .70
  horsepower (MAX)

Mechanical Components (list)

• Go kart wheel
• Bearings
• Sprockets
• Chain
• Hubs
• Axel
• Sheet metal (frame)
• Angle irons

9
Programming

• Motor turns as a function of the change in angle
• Board doesnt start until leveled
• If the angle is too great the board cuts off and
  needs to be leveled again to regain its
  functionality
• If the occupant falls off, the board will stop
  once leveled

10
Improvements

• Occupancy sensors that act like an on/off
  switch.
• Lighter versions to maximize efficiency.
• Knob to set the sensitivity.
• Knob leveling control (be able go uphill /
  downhill ).
