(A) Snapshots of predictive dynamics results of cyclic walking motion without a backpack;
(B) results of predictive dynamics of walking motion with a 60-lb backpack.
external load compared with a load of 60 lbs is shown in
Figures 7.21A and
7.21B
, respectively. A reasonable spine bending is observed with increasing back-
pack weight. The joint angle profiles, the GRFs, and joint torque profiles are
illustrated in
Figures 7.22, 7.23, and 7.24
, respectively.
