Between <strong>ROV<\/strong>, <strong>AUV<\/strong> and <strong>USV<\/strong>, In this context, it's difficult to know which solution to choose for an inspection, mapping or environmental mission.<\/p>\n\n\n\n<p>At <strong>ROV Expert<\/strong>, We support manufacturers, ports, dams and offshore players in the selection and integration of these systems. Here's a clear guide to the differences.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is an ROV?<\/h2>\n\n\n\n<p>A <strong>ROV (Remotely Operated Vehicle)<\/strong> is an underwater robot controlled from the surface via a cable (umbilical).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A well-known example:<\/h3>\n\n\n\n<p>BlueROV2<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u2705 Advantages :<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Real-time control<\/li>\n\n\n\n<li>Ideal for precise visual inspection<\/li>\n\n\n\n<li>Possibility of adding manipulator arm, sonar, DVL...<\/li>\n\n\n\n<li>Immediate response to problems<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">\u274c Limits:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dependent on an umbilical<\/li>\n\n\n\n<li>Mobility limited by cable length<\/li>\n\n\n\n<li>Requires an operator<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">\ud83d\udccc Typical use cases :<\/h3>\n\n\n\n<ul

<strong>the most versatile solution for industrial inspection<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is an AUV?<\/h2>\n\n\n\n<p>A <strong>AUV (Autonomous Underwater Vehicle)<\/strong> is an autonomous underwater robot that executes a programmed mission without a real-time pilot.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Main features :<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>INS \/ DVL \/ sonar navigation<\/li>\n\n\n\n<li>Pre-programmed missions<\/li>\n\n\n\n<li>Battery-operated<\/li>\n\n\n\n<li>Often

is an SVU?<\/h2>\n\n\n\n<p>A <strong>USV (Unmanned Surface Vehicle)<\/strong> is a marine surface drone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example:<\/h3>\n\n\n\n<p>BlueBoat<\/p>\n\n\n\n<h3
