An eight year old has Arthrogryposis, a condition which prevents him from using his arms and walking. He has access to several mobility devices; however, they are all unfit for use in a classroom setting. The student writes using his feet and works at a specialized desk. The goal of the project was to design a custom mobility device for the student’s specific needs. A device was created that could easily navigate in a classroom, while still providing a comfortable, ergonomic seat and a safe, stable platform that would allow him to work at his desk. The main features of the device include: a zero turning radius, lateral support, lockable wheels and adjustability for his growth. The device was successfully tested and met with enthusiastic acceptance from both the client and school personnel.
