3. Agenda • Problem Statement • Current Product • Expected Project benefits • Deliverables • Customer Requirements • Benchmarking Specs • Engineering Requirements

4. Problem Statement • Current State • Current anti-roll back devices exist that can be added onto wheel chairs, as well as motorized wheel chairs to provide movement assistance • Majority of manual chairs do not come standard with these devices • Many of these assistance devices are expensive and inhibit some of the benefits of manual chairs • Desired State • The device should maintain all of the benefits of a manual wheel chair(light weight, small turning radius, compact, etc.) • The device should also be able to aid the user when traversing inclines and declines, as well as prevent roll back when moving up an incline • Project Goals • Design a system that encompasses the desired properties while maintaining the key benefits of a manual chair • Key Desired Properties • Ability to provide movement assist up inclines • Ability to decelerate the user when moving down declines • Ability to prevent the wheel chair from rolling back down a hill and slipping out from under user • Constraints • The wheel chair should still meet ADA standards regarding size constraints(doorways, buildings, etc.) • System Cost
