  1. Active Ankle Foot Orthotic(AFO) Design Project Management

  2. Introduction to the Team Mentor Team Members Shane Reardon - (ME) Travis Blais- (ME) Diane Kang - (IE) Austin Frazer – (ME) Gerald Garavuso Sponsors Dr. Lamkin Kennard Dr. Debartolo Christopher Sullivan

  3. Table of Contents • Problem Definition • Background • Benchmarking • Limitations of Current AFOs • Stakeholders • Affinity Diagram • Summary/Conclusions • Questions

  4. Problem Definition • Lay out roadmap for air muscle-driven active Ankle-Foot Orthotic • Eliminate the condition known as “foot drop” Midstance Foot Drop (Between Propulsive and Contact Phase)

  5. Problem Definition Cont. • Benefactors include stroke survivors, those affected by Multiple Sclerosis (MS) and etc. • Promote natural gait • Does NOT include the propulsion stage of gait. • Ultimately identify a group of MSD projects to develop active AFO subsystems.

  6. Background • Air muscles are capable of lifting weight of human foot • Robo-Ant, hand, Underwater Crab MSD projects have already utilized air muscles in their design • Bountiful data exists characterizing air muscle behavior • A terrain sensing system is already in development (Christopher Sullivan)

  7. Benchmarking Passive Active

  8. Limitations of Current AFOs • Doesn’t allow the range of motion for plantar flexion • Only suitable for walking on level surfaces • Bulky/Heavy • Difficult to put on/take off • Must be custom fit

  9. Stakeholders • Dr. Debartolo • Dr. Lamkin Kennard • Christopher (Chappy) Sullivan • Patients • Medical Professionals (Doctors & Physical Therapists) • Manufacturers

  10. Affinity Diagram R12000 Affinity Diagram

  11. Summary/Conclusions • Current AFOs have proven insufficient to patients suffering from foot drop • An active AFO could enable patients to safely travel at variable speeds and terrain • Our job is to identify a group of MSD projects to develop active AFO subsystems utilizing air muscle technology.
