We purchased all new hardware to limit the occurrence of the problem, but we were still limited in the range of the antenna, so any long distance testing could trigger problems. \u00a0We adjusted our flight plans accordingly.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Weather (20) was a significant risk that we could not do much about. We limited the impact of this by planning ahead and testing as much as possible while we could, though we still got behind in our test plan over the course of the semester when work schedule did not match well with the weather schedule.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(9) was related to availability of a testing ground. We did a significant amount of testing in Schenley Park, but people in the past had been hassled by park staff for flying. \u00a0This did not occur to us until the day of SVE, but we had a backup flight area of NREC (through Dimi) that we could access if Schenley Park became unavailable to us.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">(10) related to the processing of FPV frames to keep the system real-time. \u00a0This was mostly dependant on the WiFi connection (addressed earlier) and the amount of data passed through. \u00a0We limited the amount of data as much as possible and had plans to downsample the number of buffered frames if the frame rate became a significant problem.<\/span><\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-777 img-responsive\" src=\"http:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-content\/uploads\/sites\/24\/2018\/05\/risk.png\" alt=\"\" width=\"1147\" height=\"616\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Figure below\u00a0shows the risks that we were tracking throughout the Spring Semester. \u00a0Some notes on some major risks and their mitigation strategies: (14) related to the weight of the drone being too heavy for flight. \u00a0This was a significant problem at the beginning of the Spring semester, with us projected to be 300 grams overweight, &#8230; <a href=\"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/risks-and-mitigation\/\" class=\"more-link text-uppercase small\"><strong>Continue Reading<\/strong> <i class=\"fa fa-angle-double-right\" aria-hidden=\"true\"><\/i><\/a><\/p>\n","protected":false},"author":107,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-656","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/pages\/656","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/users\/107"}],"replies":[{"embeddable":true,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/comments?post=656"}],"version-history":[{"count":3,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/pages\/656\/revisions"}],"predecessor-version":[{"id":779,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/pages\/656\/revisions\/779"}],"wp:attachment":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2017teamc\/wp-json\/wp\/v2\/media?parent=656"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
