Abstract:
Mobility limitations present significant challenges for individuals with physical disabilities, particularly in low- and middle-income countries where access to advanced assistive devices is restricted by high costs and limited availability. Commercial standing wheelchairs, while offering important health and social benefits through their ability to assist users in both sitting and standing positions, remain out of reach for most due to their prohibitive price and reliance on proprietary components. This study introduces the Kinesis Pro—a novel, low-cost motorized standing wheelchair designed to address these barriers through the use of locally sourced materials, open-source electronics, and a modular, user-centered approach. The Kinesis Pro integrates essential posture transition and mobility features within a robust, ergonomic frame, and utilizes a cost-effective electrical and mechanical system for reliable performance. Field testing and engineering analysis demonstrated that the Kinesis Pro provides smooth, safe transitions between sitting and standing, supports users up to 130 kg, and offers comparable core functionality to premium commercial models at a fraction of the price. Unlike existing solutions, which often require specialized maintenance and are inaccessible in resource-limited environments, the Kinesis Pro emphasizes affordability, ease of repair, and adaptability to different user needs. This work demonstrates the potential for innovative engineering to deliver essential mobility solutions to underserved populations and provides a foundation for future enhancements, including smart sensor integration and expanded customization.
