This paper presents a vortex field analysis of a four-joint robotic fish using the Viscous Vortex Domain (VVD) method. Firstly, the structural composition of the robotic fish is briefly introduced. Secondly, by establishing discrete Lagrangian mesh points and analyzing the fish's oscillation posture based on discrete vortex field points, the swimming performance of the robotic fish in a flowing vortex field and its oscillation posture in a stationary vortex field are analyzed.
The conventional Delta robot has a simple structure, high speed, and high motion accuracy, but it cannot meet the problem of robots with angular requirements because it has only three translational degrees of freedom. The tensegrity structure is composed of a series of discontinuous compression units and continuous tension units, which can form a lightweight and high stiffness structure by connecting independent rigid elements with elastic cables due to its light weight and flexible motion. Combining the Delta robot and the characteristics of the tensegrity structure, we design a 5- DOF robot and analyze its inverse kinematics.
