Objectives:

  • To develop a prototype of an electric wheelchair with power seat functions that is, reclining, footrest elevation, seat tilting and seat height adjustment.
  • To implement forward and backward motions, stopping, and turning with reduced jerk, including zero-radius turning.
  • To control the wheelchair remotely using wireless technology

Development of a Multifunctional Wheelchair for Individuals with Muscular Dystrophy

Assembly

Assembly

Understanding Muscular Dystrophy Muscular Dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration. Individuals with MD often face challenges in mobility, particularly as the disease progresses. Our wheelchair prototype aims to provide essential support and independence for these individuals, allowing them to engage more fully in daily activities. Development Process The development of this prototype involved extensive research and testing. Our team, consisting of students Chris Edberg and Devendra Singh Parihar, worked under the mentorship of Dr. K V Gangadharan at the Centre for System Design (CSD). The team focused on identifying the specific requirements of individuals with MD, and the prototype underwent rigorous testing to evaluate its functionalities and identify areas for improvement. This innovative wheelchair prototype addresses the unique needs of individuals with Muscular Dystrophy. Muscular dystrophy is a progressive neuromuscular disorder that severely impacts mobility and quality of life. The project involves creating a powered wheelchair capable of essential functions such as seat tilt, recline, footrest elevation, and height adjustment. Designed for affordability and ease of use, the wheelchair integrates advanced control systems, including wireless operation and user-centric features, to promote independence. It also considers safety, stability, and therapeutic benefits, such as improved posture, pressure relief, and circulation. wheelchair prototype represents a significant advancement in assistive technology for individuals with Muscular Dystrophy. By integrating advanced features and prioritizing user safety, we aim to empower individuals with MD, providing them with greater independence and improved quality of life. Challenges and Future Work Challenges Identified: Wireless communication disconnection issues. Jerky start and stop during movement. Different rotation speeds of drive wheels affecting straight motion. Proposed Improvements: Resolve communication errors for stable wireless operations. Implement safety measures such as speed control at maximum seat height and prevention of unsafe seat angles. Upgrade mechanical design to reduce weight while maintaining structural integrity.
