利用昆虫肌肉组织的生物致动器由于其体积小、自驱动特性、自修复能力、鲁棒性以及比哺乳动物细胞需要更少的环境管理而引起了全世界研究人员的关注。为了证明昆虫肌肉组织作为生物致动器的潜力，三种类型的这些机器人，一个支柱致动器，一个步行者，和一个twizzer，已经设计和制造。然而，昆虫肌肉组织驱动的游泳机器人模型，能够漂浮和游泳的解决方案尚未报告。因此，在本文中，我们提出了一个昆虫肌肉组织驱动的自主微型游泳机器人，在室温下工作，不需要温度和pH值的维护原型。为了设计一个能够利用昆虫背侧血管（DV）的力游泳的实用机器人身体，我们首先测量了DV的收缩力。然后，设计了游泳机器人的身体，并通过使用测量收缩力的条件下的仿真来确认设计。在此之后，我们制作的机器人身体使用聚二甲基硅氧烷（PDMS）。PDMS主体从通过立体光刻方法制造的模具获得。最后，我们将DV小心地附着到PDMS本体上，完成了游泳机器人的装配。结果表明，利用昆虫DV组织的自发收缩，微型游泳机器人能够以11.7 μm/s的平均速度自主游动。这些结果表明，昆虫DV具有用作在溶液中漂浮和游泳的生物致动器的潜力。
Bio-actuators that use insect muscular tissue have attracted attention from researchers worldwide because of their small size, self-motive property, self-repairer ability, robustness, and the need for less environment management than mammalian cells. To demonstrate the potential of insect muscular tissue for use as bio-actuators, three types of these robots, a pillar actuator, a walker, and a twizzer, have been designed and fabricated. However, a model of an insect muscular tissue-powered swimming robot that is able to float and swim in a solution has not yet been reported. Therefore, in this paper, we present a prototype of an insect muscular tissue-powered autonomous micro swimming robot that operates at room temperature and requires no temperature and pH maintenance. To design a practical robot body that is capable of swimming by using the force of the insect dorsal vessel (DV), we first measured the contraction force of the DV. Then, the body of the swimming robot was designed, and the design was confirmed by a simulation that used the condition of measured contraction force. After that, we fabricated the robot body using polydimethylpolysiloxane (PDMS). The PDMS body was obtained from a mold that was fabricated by a stereo lithography method. Finally, we carefully attached the DV to the PDMS body to complete the assembly of the swimming robot. As a result, we confirmed the micro swimming robot swam autonomously at an average velocity of 11.7 μm/s using spontaneous contractions of the complete insect DV tissue. These results demonstrated that the insect DV has potential for use as a bio-actuator for floating and swimming in solution.
