GermanyA research team from the School of Mechanical System Engineering at Seoul National University of Science and Technology has developed porous foot pads for quadruped robots using Triply Periodic Minimal Surfaces (TPMS). These foot pads store impact energy during movement and release it during propulsion, significantly reducing the energy consumption of legged robots. Legged robots typically require more energy for locomotion compared to wheeled counterparts, limiting their operational duration. The researchers used 3D printing to create three different TPMS-based foot pad designs, 'Primitive,' 'Gyroid,' and 'Diamond', each with varying structures and densities. They tested these designs during walking, which is the least efficient gait for energy recovery in legged robots. To optimize energy usage, the team employed deep reinforcement learning to adjust motor control, minimizing energy expenditure during force application. Tests showed up to a 6.2% reduction in power consumption during slow walking speeds between 0.4 and 1.0 meters per second, with minimal impact on the robot's stability and gait characteristics.
