The Viscocise

Making Exercise Accessible to EVERYONE !

Section Yellow-B

Overview

n The Need n The Device n Lessons Learned

q Kinematics q Calculations q Next Iteration

n Market Analysis

The Need

n 30% of U.S. deaths in 2000 due to lack of

physical activity, smoking, and poor diet.

n 43.4% of elderly deaths caused by heart

disease, stroke, and diabetes.

n 32.9% of elderly without physical exercise for

the past month.

n 19.5% of elderly are obese.

The Solution

The Viscocise

The benefits of water aerobics on land

Advantages

n No stored energy

q Safer than weights or springs.

n Does not constrain motion

q Same degrees of freedom as the body

n Matches the force of the user

q Viscous damping acts as a passive feedback system

n Dual-direction resistance

q Exercises complementary muscle groups.

Calculations

n Maximum Torque: ~40 Nm n Average Joint Rotational Speed: ~1 rad/s n Linear Damper (10cm moment arm):

q Maximum Force: 400 N q Damping Coefficient: 40 N•s/m

n Rotary Damper (1:1 gear ratio):

q Maximum Torque: 40 N•m q Damping Coefficient: 40 N•m•s/rad

Preliminary Testing Sketch Model

The Next Iteration

n Damper Selection

q Rotary damping for elbow joints q Oil-based dampers

n Proper Ergonomics

q Mirror human joints q Dual support handle to eliminate torque on wrist

Market

n 35+ million elderly in U.S. n Increased physical activity could save $77+

billion in medical expenses.

n 95% of elderly health care spending on

chronic diseases (i.e. diabetes, heart disease and stroke, cancer and arthritis).

Benefits of Exercise

n Contributes to overall fitness including bone and

muscle strength, flexibility, and weight control.

n Helps prevent

q Coronary Heart Disease q Obesity q Arthritis q High Blood Pressure q Diabetes q Osteoporosis q Stroke q Depression

n Decreases injury and surgery recovery time.
