    Abstract: A frame for constructing nerve tract is provided, including microcatheters, a support, and a shell. The shell is configured to contain a culture medium inside. The microcatheters are configured to culture nerve cells. The multiple microcatheters are suspended and fixed into the shell by the support, the microcatheters are arranged along a direction from one end to the other end of the shell, catheter walls of the microcatheters are provided with through holes, the nerve cells in the microcatheter cannot flow out through the through holes, and the culture medium enters the microcatheter through the through holes. A method for constructing nerve tract based on the frame described is provided, including: filling the nerve cells wrapped with a collagen hydrogel stock solution into the microcatheters, and after the collagen hydrogel stock solution is completely cross-linked, placing the frame loaded with the nerve cells in a culture device for perfusion culture.

    Abstract: A waist imitating device of robotic rat based on multiple-connecting-rod transmission comprises a pitch parallel connecting rod group (8) and a yaw parallel connecting rod group (2). The pitch parallel connecting rod group (8) and the yaw parallel connecting rod group (2) are respectively connected with a front joint and a back joint of a waist of a robotic rat. Under the drive of a first motor (4), crank connecting rods drive the yaw parallel connecting rod group (2) such that left-right yaw motion of the waist of the robotic rat relative to wheels and forelimbs can be achieved. Under the drive of a second motor (14), crank connecting rods drive the pitch parallel connecting rod group (8) such that upper-down pitch motion of the waist of the robotic rat relative to the wheels and the forelimbs can be achieved.
