    This study introduces a simple controller to prevent electric wheelchairs from veering off course due to uneven wheel speeds. The system ensures straight-line travel by equalizing wheel speeds for improved maneuverability.

    Area of Science:

    • Robotics and Control Systems
    • Assistive Technology Engineering

    Background:

    • Electric wheelchairs can deviate from a straight path due to imbalances in wheel loading, motor power, or uneven terrain.
    • This curved-path operation poses a challenge for precise navigation and user control.

    Purpose of the Study:

    • To develop and present a straightforward control system for electric wheelchairs to counteract unwanted curved-path operation.
    • To enhance the straight-line stability and maneuverability of electric wheelchairs.

    Main Methods:

    • Implementing a control system that monitors the rotational speeds of the wheelchair's wheels.
    • Applying corrective actions to equalize wheel speeds, thereby maintaining a straight trajectory.

    Main Results:

    Related Experiment Videos

  • The controller effectively senses wheel speed discrepancies.
  • Corrections are applied to maintain equal wheel speeds, mitigating curved-path deviations.
  • A basic electric conversion kit for manual wheelchairs is also demonstrated.

    • Conclusions:

    • The proposed simple control system is effective in correcting unwanted curved-path operation in electric wheelchairs.
    • This solution enhances the usability and straight-line stability of electric wheelchairs.
    • The presented electric conversion offers a potential upgrade for manual wheelchairs.
