It sounds complicated, but it&#8217;s really just a computerized version of what we humans think of as &#8220;common sense.&#8221; For example, if someone asks you to bring them a cup without telling you exactly where the cup is, you&#8217;re probably clever enough to infer that cups can be found in drawers or cabinets or dishwashers, and that drawers and cabinets and dishwashers are all usually located in a kitchen, so you can go to the kitchen, poke around for a little bit, and find a cup. Semantic search allows robots to do the same sort of thing.<\/p><\/blockquote>\n<p>So PR2 didn&#8217;t exactly &#8220;know&#8221; where to find the sandwich, but was able to figure it out by consulting info in its database, and then searching the areas where a sandwich was likely to be.<\/p>\n<p>PR2\u00a0can also\u00a0<a href=\"http:\/\/spectrum.ieee.org\/automaton\/robotics\/artificial-intelligence\/pr2-successfully-bakes-giant-cookie-from-scratch\" target=\"_blank\" rel=\"noopener\">bake cookies<\/a> and <a href=\"http:\/\/spectrum.ieee.org\/automaton\/robotics\/diy\/pr2-and-turtlebot-team-up-to-bring-you-drinks\" target=\"_blank\" rel=\"noopener\">serve drinks<\/a>&#8230; cool, eh?<\/p>\n<p>(h\/t <a href=\"http:\/\/www.eater.com\/2011\/10\/4\/6646543\/watch-a-robot-go-on-a-sandwich-run\" target=\"_blank\" rel=\"noopener\">Eater.com<\/a>)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I thought this vid was pretty amusing: According to IEEE Spectrum, what seems to be an overly high-tech, time-consuming\u00a0way to snag some lunch, is an example of &#8220;semantic [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[15,22],"tags":[],"_links":{"self":[{"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/posts\/5407"}],"collection":[{"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/comments?post=5407"}],"version-history":[{"count":3,"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/posts\/5407\/revisions"}],"predecessor-version":[{"id":9378,"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/posts\/5407\/revisions\/9378"}],"wp:attachment":[{"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/media?parent=5407"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/categories?post=5407"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ultimatefatburner.com\/ufb-blog\/wp-json\/wp\/v2\/tags?post=5407"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
