The robots switch searching and resting behavior in a distributed manner to perform foraging quickly and energy efficiently. It is known that robots that are resting can act as a potential labor pool in addition to saving energy. Because they function as a potential labor pool, resting robots can help with foraging if needed. In this study, we consider the group foraging task, which requires two or more robots to transport a food item. In a group foraging task, resting robots can help with the transportation of a heavy food item in response to the recruitment of other robots. Until now, the efficacy of the resting behavior as a potential labor pool has been suggested, but the environments in which this function is dominant is still unknown. In this study, we propose a state-transition model for robots that includes the resting behavior and investigate the performance through multi-agent simulation. By comparing models with and without the resting behavior, we found that the function of the resting behavior as a potential labor pool is dominant in cases when the food items are heavy or the population is small.<\/jats:p>","DOI":"10.1177\/10597123241309184","type":"journal-article","created":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T18:35:26Z","timestamp":1741113326000},"page":"197-220","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Investigating dominant situation of resting behavior as a potential labor pool in robotic swarm for group foraging"],"prefix":"10.1177","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2402-5179","authenticated-orcid":false,"given":"Tomohiro","family":"Hayakawa","sequence":"first","affiliation":[{"name":"Faculty of Engineering, Department of Mechanical Engineering, Shizuoka University, Hamamatsu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiyuki","family":"Yasuda","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Toyama, Toyama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumitoshi","family":"Matsuno","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Department of Electronics and Information Systems Engineering, Osaka Institute of Technology, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,3,4]]},"reference":[{"key":"e_1_3_4_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/rob.20403"},{"key":"e_1_3_4_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2015.05.116"},{"key":"e_1_3_4_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2011.2111450"},{"key":"e_1_3_4_5_1","doi-asserted-by":"publisher","DOI":"10.1006\/bulm.1998.0041"},{"key":"e_1_3_4_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11721-012-0075-2"},{"key":"e_1_3_4_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10458-012-9212-y"},{"key":"e_1_3_4_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11721-015-0117-7"},{"key":"e_1_3_4_9_1","first-page":"259","article-title":"Task allocation for a robotic swarm based on an adaptive response threshold model","author":"Castello E.","year":"2013","unstructured":"Castello E., Yamamoto T., Nakamura Y., Ishiguro H.
