Due to the large number of emergencies and disasters happening around the globe, the technology development to face these difficulties has risen in different areas, one of them being the robotics field: rescue robots. A great amount of incentives have been presented over the years to increase the numbers of studies in the creation of rescue robots, like competitions and funding opportunities. The objective of writing this paper is to document and review different rescue robot works to provide, to interested individuals in the research area, a basis to start in this field. Twenty-six articles on rescue robotics development, ranging from 2017 to 2021, were found and selected using academic search engines.
