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

6. Advantages No stored energy Does not constrain motion
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
