This design helps reduce oil leakage and ignition risks in environments where conventional systems may be difficult to use.<\/div>\n<\/details>\n<details class=\"faq-item\">\n<summary>In what types of environments can the robot operate?<\/summary>\n<div class=\"faq-answer\">The system is intended for demanding environments such as underwater and marine locations, areas containing flammable gases, radiation environments, industrial plants, and infrastructure or disaster-response sites.<\/div>\n<\/details>\n<details class=\"faq-item\">\n<summary>How much weight can the water-hydraulic system handle?<\/summary>\n<div class=\"faq-answer\">The exhibited system uses a pump that generates 4 MPa of pressure. According to the demonstration, a single cylinder can lift and lower a load of up to 200 kg.<\/div>\n<\/details>\n<\/div>\n<details class=\"video-transcript\">\n<summary>View video transcript<\/summary>\n<div class=\"transcript-content\">We are NACOL CO., LTD.. This time, we are exhibiting an extreme work robot powered by water pressure.<br \/>As a manufacturer of water pressure equipment,we make water pumps, valves, cylinders, and so on.<br \/>We combined our equipment to create this robotic arm.<br \/>Its key feature is that it uses only water, so there is no electricity or oil whatsoever.<br \/>This allows us to create robots that can operate in various environments, such as underwater, in the sea, around flammable gases, or in radioactive environments.<br \/>Normally, with conventional water pressure, it&#8217;s either water flowing or no water flowing- an all-or-nothing situation.<br \/>However, the proportional valve we have developed allows us to seamlessly change not only the direction of the water but also the flow rate.<br \/>This proportional valve allows the robot to move freely and seamlessly, resulting in smooth movements.<br \/>Furthermore, the pump has 4M of pressure, so, for example, this single cylinder can lift and lower an object weighing 200kg.<br \/>We primarily manufacture hydraulic equipment,but we also develop simple robots like this one, as well as software for operating valves like these, in-house, so please feel free to contact us.<\/div>\n<\/details>\n<h2>Contact the Company<\/h2>\n<div class=\"company-profile-section\">\n<div class=\"company-shot\">\n<div class=\"browser-shot alignnone\"><a href=\"https:\/\/www.nacol.co.jp\/\" target=\"_blank\"><img fetchpriority=\"high\" decoding=\"async\"src=\"https:\/\/s0.wp.com\/mshots\/v1\/https%3A%2F%2Fwww.nacol.co.jp%2F?w=600&#038;h=450\"alt=\"Screenshot of the company website\"width=\"600\"height=\"450\"class=\"alignnone\"><\/a><\/div>\n<\/div>\n<div class=\"company-info\">\n<h3 class=\"company-name\">NACOL CO., LTD.<\/h3>\n<ul class=\"company-meta\">\n<li><span class=\"label\">Headquarters<\/span> <span class=\"value\">415 Nishikubo, Shimizu-ku, Shizuoka-shi, Shizuoka 424-0038, Japan<\/span><\/li>\n<li><span class=\"label\">Established<\/span> <span class=\"value\">August 16, 1955<\/span><\/li>\n<li><span class=\"label\">Employees<\/span> <span class=\"value\">77 (local)<\/span><\/li>\n<li><span class=\"label\">Official Website<\/span> <span class=\"value\"><a href=\"https:\/\/www.nacol.co.jp\/\" target=\"_blank\" rel=\"noopener\">https:\/\/www.nacol.co.jp\/<\/a><\/span><\/li>\n<li><span class=\"label\">Business Area<\/span> <span class=\"value\">Fluid power equipment, hydraulic equipment, and water-hydraulic equipment<\/span><\/li>\n<li><span class=\"label\">Main Products and Services<\/span> <span class=\"value\">Hydraulic accumulators, backup bottles, hydraulic tank air regulators, hydraulic valves, water-driven pumps and motors, proportional valves, NADS water-drive systems, and valve-control software<\/span><\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div id=\"world-1227714066\" class=\"world- world-entity-placement\"><p style=\"text-align: center;\">\u25c7<\/p>\n<p>Thinking of Exhibiting?<br \/>\nFrom exhibition video streaming to booth design &amp;
