A single robot can load and transport polystyrene beads up to 3 microns in diameter,while swarms of robots can transport goods up to 30 microns in diameter.In addition,the comparison of transportation distance and transportation volume shows that the swarm is up to 5 times more efficient in transportation compared to a single robot.

By demonstrating that molecular machines can be engineered to swarm and cooperatively deliver goods efficiently,this research lays the foundation for the application of microrobots in various fields.”In the near future,expect to see swarms of microrobots being used for drug delivery,pollutant collection,molecular power generation devices,and tiny detection devices,”said the researchers.

单台机器人可装载和运输直径达3微米的聚苯乙烯珠子，而成群结队的机器人可以运输直径达30微米的货物。此外，运输距离和运输量的比较表明，与单一机器人相比，集群的运输效率最高可达5倍。

通过证明分子机器可被设计成集群并协作高效地运送货物，这项研究为微型机器人在各个领域的应用奠定了基础。研究人员表示：“在不久的将来，预计将看到微型机器人群被用于药物输送、污染物收集、分子发电设备和微型检测设备。”
