    Area of Science:

    • Mechanical Engineering
    • Robotics
    • Assistive Technology

    Background:

    • Electric wheelchairs currently face limitations in power efficiency and operational range.
    • Direct-drive systems in wheelchairs can be inefficient, especially under varying loads like inclines.

    Purpose of the Study:

    • To introduce and evaluate the RESATRAN (Resonant Speed Automatic Transmission), an infinitely variable transmission for electric wheelchairs.
    • To demonstrate the potential for improved energy efficiency and extended operational range in electric wheelchairs.

    Main Methods:

    • Development and testing of a prototype RESATRAN system integrated into a three-wheeled electric wheelchair.
    • Theoretical analysis of power reduction during hill climbing compared to direct-drive systems.
    • Empirical testing of the transmission's performance on a defined test course.

    Main Results:

    • Theoretical analysis indicates over 50% power reduction during hill climbing with RESATRAN compared to direct-drive.
    • Prototype testing showed substantial reductions in operating current.
    • Increased operational distance was observed for the same battery charge on the test course.

    Conclusions:

    • The RESATRAN offers significant improvements in energy efficiency for electric wheelchairs.
    • This transmission enables the use of smaller motors and control systems, reducing overall cost and weight.
    • RESATRAN technology has the potential to greatly enhance the usability and accessibility of electric wheelchairs.
