  1. Team Yellow: Section B Sketch Model Presentation Aaron Doody Harmeet Gill Moneer Helu Adam Leeb David Lopez Zack Reynolds Taylor Roan

  2. The Viscocise Making Exercise Accessible to EVERYONE ! Section Yellow-B

  3. Overview • The Need • The Device • Lessons Learned • Kinematics • Calculations • Next Iteration • Market Analysis

  4. The Need • 30% of U.S. deaths in 2000 due to lack of physical activity, smoking, and poor diet. • 43.4% of elderly deaths caused by heart disease, stroke, and diabetes. • 32.9% of elderly without physical exercise for the past month. • 19.5% of elderly are obese.

  5. The Solution The Viscocise The benefits of water aerobics on land

  6. Advantages • No stored energy • Safer than weights or springs. • Does not constrain motion • Same degrees of freedom as the body • Matches the force of the user • Viscous damping acts as a passive feedback system • Dual-direction resistance • Exercises complementary muscle groups.

  7. Calculations • Maximum Torque: ~40 Nm • Average Joint Rotational Speed: ~1 rad/s • Linear Damper (10cm moment arm): • Maximum Force: 400 N • Damping Coefficient: 40 N•s/m • Rotary Damper (1:1 gear ratio): • Maximum Torque: 40 N•m • Damping Coefficient: 40 N•m•s/rad

  8. Preliminary Testing Sketch Model

  9. The Next Iteration • Damper Selection • Rotary damping for elbow joints • Oil-based dampers • Proper Ergonomics • Mirror human joints • Dual support handle to eliminate torque on wrist • Contact: Kristina Martin Director of Aquatic & Fitness Programs Zesiger Sports and Fitness Center

  10. Market • 35+ million elderly in U.S. • Increased physical activity could save $77+ billion in medical expenses. • 95% of elderly health care spending on chronic diseases (i.e. diabetes, heart disease and stroke, cancer and arthritis).

  11. Questions? • (Insert Question Here…) • Thank you for your time and consideration.

  12. Cost (~$50) • Joints: $2 • Structural Members: $10 • Dampers: $10 • Seat: $5 • Manufacturing Cost: ~$20

  13. Benefits of Exercise • Contributes to overall fitness including bone and muscle strength, flexibility, and weight control. • Helps prevent • Coronary Heart Disease • Obesity • Arthritis • High Blood Pressure • Diabetes • Osteoporosis • Stroke • Depression • Decreases injury and surgery recovery time.
