Exploring the Enhanced Performance of RobDact: A Bionic Underwater Vehicle Inspired by Pectoral Fins of the Fish Dactylopteridae

The bionic underwater vehicle is inspired by the fish with large pectoral fins

Underwater robots have become a popular tool for a wide range of marine tasks. RobDact, a bionic underwater vehicle inspired by the Dactylopteridae fish with its large pectoral fins, is an example of such a bionic underwater device. The RobDact was studied by a research team that combined computational fluid dynamics with a force measurement test. This resulted in an accurate hydrodynamic RobDact model, which allows for better vehicle control.

The team will publish their findings in Cyborg & Bionic Systems by May 31, 2022.

Underwater robots can be used to perform a wide range of marine tasks. They are also useful for mapping, exploring the ocean floor, and in the fishing industry. The propeller is used to drive most of the traditional underwater robotics, which are good for cruising at a steady speed in open water. Underwater robots are often required to hover or move at low speeds while performing specific tasks in turbulent water. In these conditions, the propeller has a difficult time moving the robot. The propeller \”twitching movement\” is another factor that can affect the underwater robot’s performance when it is moving slowly in turbulent waters. This twitching creates fluid pulses which reduce the robot’s effectiveness.
