  1. Stationary Balance Training Bicycle - P08001 • Team Members: • Jennifer Zelasko - IE • Carl Mangelsdorf - ME • Jeff Tempest - ME • James Nardo – ME • Jonathan Bawas – EE Sponsored by The National Science Foundation under Award No. BES-0527358

  2. Project Description • Customer: Nazareth College Physical Therapy Clinic • Safe intermediate step between a stationary and traditional bicycle • Balance training for recovering physical therapy patients • Stroke • Neurological disorders

  3. Customer Key Needs / Specs

  4. Concept Overview Pulley Mechanism Pivoting Arm w/ Locked Positions Spring compression adjusted with Winch Telescoping Seat Height w/ Pin-lock Pillow Block Ball Bearing To Allow Lateral Tilt (X2) Wheels For Portability Pin-lock control for upright “Locked Position” Friction Resistance Pedals

  5. Concept Overview - Feedback • Audio / Visual Display Concept • Visual Feedback • LED Bank – indicating direction and level of tilt • Color Code • Green – normal tilt range • Yellow – region to correct balance • Red – Tip-over condition imminent • Audio Feedback • 2 Buzzers provides audio feedback • Auditory indication occur at yellow and red warning levels • Two tones • Slow Pulsed tone for “yellow” level • Fast pulse tone for “Red” Level

  6. System Architecture

  7. Final Design Summary • Leg brace supports: keep self aligning bearings perpendicular to axle • Handlebar adjustments: rotation at T-connection not necessary to achieve design specs • Feedback system: buffer used in place of comparator to simplify adjustments

  8. Testing Results • Design meets all customer needs • Analysis of design meets engineering specifications for full system and subsystems • However, execution of our current test plan may reveal unforeseeable complications • Tilt range specification is overestimated, final calibration will refine final tilt range • Budget Considerations: • On target to meet project budget of $2000 • Current Total Cost of Parts = $1,717.14 • $282.86 left forshipping and small miscellaneous items • Schedule: on target • All key components are in stock with our selected suppliers with short lead times. • Items that require additional testing will be ordered week 11. (Inclinometer)

  9. Objective Project Evaluation • Successes: • Failures:
