<p>➀ Researchers at Northeastern University in China have developed an H-shaped bionic robot that mimics a cheetah’s running motion using piezoelectric materials.</p><p>➁ The H-shaped bionic piezoelectric robot (H-BPR) features four legs connected by three piezoelectric beams, allowing it to mimic a cheetah’s gait through periodic leg movements.</p><p>➂ Experiments showed the robot could achieve a maximum velocity of 66.79 mm/s and a load capacity of 55 g, demonstrating potential for industrial applications and search-and-rescue missions.</p>
