Miniature and microrobots: a review of recent developments

Abstract

Purpose – This paper aims to provide an insight into recent miniaturised robot developments and applications. Design/methodology/approach – Following an introduction, this article discusses the technology and applications of miniature robots and considers swarm robotics, assembly robots, flying robots and their uses in healthcare. It concludes with a brief consideration of the emerging field of nanorobotics. Findings – This shows that all manners of miniaturised terrestrial, airborne and aquatic robots are being developed, but size and weight restraints pose considerable technological challenges, such as power sources, navigation, actuation and control. Prototypes have been developed for military, assembly, medical, environmental and other applications, as well as for furthering the understanding of swarm behaviour. In the longer term, microrobots and nanorobots offer prospects to revolutionise many aspects of healthcare, such as cancer treatment. Originality/value – This study provides details of a wide-ranging selection of miniaturised robot developments.
