quadruped

thingiverse

This design features a quadruped with two-part legs, aiming to achieve 2 degrees of freedom from one joint. Key decisions include using a cable drive and housing servos within the body instead of attaching them to the legs. The modularity allows for customizable servo sizes. The central square is not included in the downloadable files due to its size and mounting options depending on servo and electronic/sensor choices. The two-part leg prints with a 0.2mm gap, suitable for standard 3D printers. KISSlicer64 is recommended for slicing with "Avoid Crossing Perimeters" enabled, as Slic3r may cause issues. The leg parts measure about 120mm and 60mm, fitting on a 200mm x 200mm heatbed with some space or rotated 45 degrees. Feedback is encouraged for bug reports or design suggestions. Cable articulation involves threading fishing line through notches on the legs, guided by in-line and hip notches, with one servo driving opposite leg sides. Gineer R&D shares this innovative concept.
