动力源和车载驱动的小型化是制约微型移动机器人发展的主要瓶颈。作为一种可能的解决方案，这封信建议在粘质沙雷氏菌的完整细胞内使用鞭毛马达，以控制游泳机器人身体的推进。通过随机附着在表面的几种细菌，以15+/-6微米/S的平均速度推进10微米聚苯乙烯微珠，验证了所提想法的可行性。通过引入铜离子来阻止细菌鞭毛马达和乙二胺四乙酸恢复它们的运动，实现了对微珠的开关运动控制。(C)2007年美国物理研究所。
Miniaturization of the power source and on-board actuation is the main bottleneck for the development of microscale mobile robots. As a possible solution, this letter proposes the use of flagellar motors inside the intact cell of Serratia marcescens bacteria for controlled propulsion of swimming robotic bodies. The feasibility of the proposed idea is demonstrated by propelling 10 mu m polystyrene beads at an average speed of 15 +/- 6 mu m/s by several bacteria randomly attached on their surface. On/off motion control of the bead is achieved by introducing copper ions to stop the bacteria flagellar motors and ethylenediaminetetraacetic acid to resume their motion.
