Why asymmetric
Posted: Sun Dec 15, 2013 1:47 pm
hi, all
I used the gait2392 model in which muscles and joints were
distributed symmetrically. I make it fall down from a certain
height, and I think the initial acceleration for joints of left
and right legs should be the same, but the following result shows
that they were not same.
Acceleration diff. : t= 0 hip_adduction_r: -19.2421 vs hip_adduction_l: -19.2421 Difference = -3.55271e-015
Acceleration diff. : t= 0 hip_flexion_r: 2.815e-316 vs hip_flexion_l: 2.83736e-316 Difference = -2.23567e-318
Acceleration diff. : t= 0 knee_angle_r: 2.81501e-316 vs knee_angle_l: 2.815e-316 Difference = 5.92879e-322
Acceleration diff. : t= 0 ankle_angle_r: 1.4854e-313 vs ankle_angle_l: 1.2732e-313 Difference = 2.122e-314
Any ideas for this problem?
