SEGBOARD


Objectives l.jpg
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


S teps l.jpg
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


Accomplishments so far l.jpg
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


Mechanical components list l.jpg
Mechanical Components (list)

  • Go kart wheel

  • Bearings

  • Sprockets

  • Chain

  • Hubs

  • Axel

  • Sheet metal (frame)

  • Angle irons


Programming l.jpg
Programming

  • Motor turns as a function of the change in angle

  • Board doesn’t 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


Improvements l.jpg
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 ).
