Researchers at Seoul National University of Science and Technology (SEOULTECH) have developed porous 3D-printed robot feet that help quadruped robots use less battery power while walking. Their study combines advanced 3D-printed porous structures with artificial intelligence to reduce battery power consumption by up to 6.2 percent while maintaining stable walking. Porous feet deliver The researchers designed and 3D-printed three hemispherical TPMS variants—primitive, gyroid and diamond—and evaluated their mechanical properties through compression testing. Compared with conventional solid feet, the porous TPMS design reduced battery power consumption by 1.4 percent to 6.2 percent, depending on walking speed. Because TPMS structures can be manufactured using standard 3D printing techniques, the technology could also be easier and less expensive to implement in future robotic platforms.
