These parameters are the ramp angle, ramp surface friction, hip mass and size of the flatfeet.
In summary, we observed steady walking in our straightlegged mechanism with flatfeet.
Our model has lightweight, flatfeet mounted on periodically actuated ankle joints.
The same difficulty appears also in a flatfeet model.
The above observations confirmed that a two-legged mechanism with flatfeet can exhibit passive dynamic walking like those with semicircular or curved feet.
We also investigated the effects of the lengths of the flatfeet on walking.
More than a thousand responses covered a range of concerns, from the costs of disease prevention to the treatment of flatfeet and the use of magnetic resonance imaging.
It is interesting to compare the gait pattern of our walker with flatfeet to the previous work where round feet or point feet were used.
It is shown that the mechanism having flatfeet can exhibit passive dynamic walking as those with curved feet, but the walking efficiency is significantly lower.
I take the simple example of flatfeet.
