While animals are notably reactive to changes in their environment, machines often follow finely tuned yet inflexible plans. Thus, instead of the traditional approach of training such machines over many different unpredictable scenarios in detailed simulations (which is the most intuitive approach to inducing robustness), this work proposes to train machines to be reactive to their environment. The idea is that robustness may result not from detailed internal models or finely tuned control policies but from cautious exploratory behavior. Supporting this hypothesis, robots trained to navigate mazes with a reactive disposition prove more robust than those trained over many trials yet not rewarded for reactive behavior in both simulated tests and when embodied in real robots. The conclusion is that robustness may neither require an accurate model nor finely calibrated behavior.<\/jats:p>","DOI":"10.1177\/1059712313487390","type":"journal-article","created":{"date-parts":[[2013,8,20]],"date-time":"2013-08-20T23:36:46Z","timestamp":1377041806000},"page":"484-500","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Encouraging reactivity to create robust machines"],"prefix":"10.1177","volume":"21","author":[{"given":"Joel","family":"Lehman","sequence":"first","affiliation":[{"name":"The University of Texas at Austin, Austin, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian","family":"Risi","sequence":"additional","affiliation":[{"name":"Cornell University, Ithaca, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"D\u2019Ambrosio","sequence":"additional","affiliation":[{"name":"Space and Naval Warfare Systems Center Pacic, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth","family":"O Stanley","sequence":"additional","affiliation":[{"name":"University of Central Florida, Orlando, FL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,8,20]]},"reference":[{"key":"bibr1-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1140\/epjb\/e2008-00175-0"},{"key":"bibr2-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-0492-8_6"},{"key":"bibr3-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1086\/276428"},{"key":"bibr4-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1126\/science.153.3731.25"},{"key":"bibr5-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1016\/S0045-7825(99)00386-2"},{"key":"bibr6-1059712313487390","first-page":"57","volume-title":"Proceedings of the international conference on artifical life (alife9)","author":"Bongard J.","year":"2004"},{"key":"bibr7-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1126\/science.1133687"},{"key":"bibr8-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1007\/978-4-431-67869-4_12"},{"key":"bibr9-1059712313487390","first-page":"3","volume-title":"Proceedings of the european conference on artificial life","author":"Brooks R.","year":"1994"},{"key":"bibr10-1059712313487390","doi-asserted-by":"publisher","DOI":"10.1109\/TEVC.2010.2104157"},{"issue":"3","key":"bibr11-1059712313487390","first-page":"129","volume":"1","author":"Coello C.
