Abstract: A biomimetic turtle includes a trunk, a head movably connected with a front end of the trunk in the front-rear direction, two front limbs disposed on a front section of the trunk and each rotatable relative to the trunk to sway in an up-down direction, and a driving module to drive the head and the front limbs. Each front limb has a curve-shaped rigid portion with a recess, and a deformable flipper portion engaged in the recess and extending rearwardly.
