As mankind steps into the 21st century, the exploration of the ocean also enters a new phase. In the recent decades, the research on biomimetic robot fish has attracted scientific communities’ attention increasingly. With its character of high flexibility and intelligence, biomimetic robot fish have become one of the research focuses in the field of underwater robots in recent years. This paper...

In this paper we explain the mechanical design of the robot herring that we have developed. The use of mechanical accumulators is a fundamental issue in the design of this robot. Two different types of mechanical accumulators are implemented and tested as a spine on the robot. We argue that using an Euler buckled spine, on a robot fish, will give more efficient robots and a naturally occurring ...

The integration of biomimetic robots in a fish school may enable a better understanding of collective behaviour, offering a new experimental method to test group feedback in response to behavioural modulations of its 'engineered' member. Here, we analyse a robotic fish and individual golden shiners (Notemigonus crysoleucas) swimming together in a water tunnel at different flow velocities. We de...

In this paper, a novel design of a biomimetic robot fish is presented. Based on the propulsion and maneuvering mechanisms of real fishes, a tail mechanical structure with cams and connecting rods for fitting carangiform fish body wave is designed, which provides the main propulsion. Two pectoral fins are mounted, and each pectoral fin can flap separately and rotate freely. Coordinating the move...

Biomimetic robotic fish is a new type of underwater robot with many superior characteristics such as high movement speed, high motion efficiency, high energy efficiency, and so on. However, the traditional kinematic model for biomimetic robotic fish has many shortcomings which limit their movement speed, such as the rigid shakes of the fish’s head when it swims, which is caused by neglecting th...

Based on analyses of motion control on biomimetic robot fish, this paper promotes an innovative theory of curve fitting which is an idea employed from Physics, and applies it on calculation of link-based robot fish’s motion parameters by simulation. Its efficiency and availability is proved via analyzing of the results.
