Robot-assisted indoor air quality monitoring and assessment: a systematic review

The degraded air quality has become an international issue with rising cases of respiratory health issues across the globe while contributing to the symptoms of chronic health problems such as cardiovascular disease, lung cancer, and nervous system disorders. Therefore, it is important to leverage the potential of the latest technologies to address the concerns related to degrading air quality. This systematic review is focused on robot-assisted indoor air quality (IAQ) monitoring and assessment. This review is conducted based on the 14 most relevant papers included from 5 different databases, and the available information is synthesized with PRISMA guidelines to find answers to 6 potential research questions. The main contribution is to provide highlights to different types of ground robotic systems used by existing researchers for IAQ assessment. The synthesis shows that commercial robotic units are widely preferred for IAQ monitoring applications in comparison to the self-designed robot systems. The authors in this paper also put emphasis on energy consumption, power requirements, functionality details, and communication technologies used by existing researchers. This paper highlights potential challenges, gaps, and findings of the existing studies while creating a roadmap for future researchers, public health experts, and government agencies working in this domain application.
