The RobDact is one such bionic underwater vehicle, inspired by a fish called Dactylopteridae known for its enlarged pectoral fins. A research team has combined computational fluid dynamics and a force measurement experiment to study the RobDact, creating an accurate hydrodynamic model of the RobDact that allows them to better control the vehicle.<\/p>\n<p>The team published their findings in <i>Cyborg and Bionic Systems<\/i> on May 31, 2022.<\/p>\n<p>Underwater robots are now used for many marine tasks, including in the fishery industry, underwater exploration, and mapping. Most of the traditional underwater robots are driven by a propeller, which is effective for cruising in <a href=\"https:\/\/techxplore.com\/tags\/open+waters\/\" rel=\"tag\" class=\"\">open waters<\/a> at a stable speed. However, underwater robots often need to be able to move or hover at low speeds in turbulent waters, while performing a specific task. It is difficult for the propeller to move the robot in these conditions. Another factor when an <a href=\"https:\/\/techxplore.com\/tags\/underwater+robot\/\" rel=\"tag\" class=\"\">underwater robot<\/a> is moving at low speeds in unstable flowing waters is the propeller\u2019s \u201ctwitching\u201d movement. This twitching generates unpredictable fluid pulses that reduce the robot\u2019s efficiency.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Underwater robots are being widely used as tools in a variety of marine tasks.
