1. It was tested and analyzed the angle of the resting seat for comfort by blood flow from the state of the body, muscle activity, physical stability (center of pressure displacement) and so on.

2. The center of pressure is about 1 - 11 / 2 diameter in front of the center of gravity.

3. As the machine is tilted off-balance, the center of pressure acts as a fulcrum for the system to rotate around.

4. Must carry on the blanking force and the center of pressure computation once more.

5. Must carry on the blanking force and the center of pressure computation once more. is the blanking technological design finally.

6. We take the geometry method to derive the inverse kinematics and the center of pressure (COP) of the biped robot.

7. Effects of the separating ring on the normal force and the center of pressure also analysed in the light of the experimental data.

8. Result:Using this system, the ground reaction forces in three directions during walking and the trace of center of pressure(COP) oscillation during standing on the platform can be detected.

9. For this to be effective, it is necessary to keep the center of mass in normal flight directly below the center of pressure.
