我们发展了一种新的方法来制造一个像螃蟹一样的微型机器人，它可以在生理条件下长时间驱动。微型机器人的骨架是用一种生物相容性和弹性材料-聚二甲基硅氧烷（PDMS）-通过使用一个专门设计的3D成型对准器建造的，由三条PDMS“腿”连接在一个“身体”上组成。然后将心肌细胞铺在骨架的凹槽顶面上，导致高浓度的脉动细胞。这些关键技术使微型机器人能够连续行走十多天。我们的螃蟹状微型机器人的性能是在100 mm s（-1）的平均速度下测量的，估计它在一周内行驶的总距离为50 m。因此，我们首次展示了具有可靠和长期驱动性能的步行机器人。
We developed a novel method to fabricate a crab- like microrobot that can actuate for a long period in a physiological condition. The microrobot backbone was built with a biocompatible and elastic material - polydimethylsiloxane ( PDMS) - by using a specially designed 3D molding aligner, and consisted of three strips of PDMS "legs'' connected across a "body.'' Cardiomyocytes were then plated on the grooved top surface of the backbone, resulting in a high concentration of pulsating cells. These key techniques enabled the microrobot to walk continuously for over ten days. The performance of our crab- like microrobot was measured at an average velocity of 100 mm s(-1), and the estimated total distance it travelled was 50 m over a one-week period. Thus, we have demonstrated for the first time a walking robot that exhibited reliable and long-term actuation performances.
