Problems solved by technology

The traditional control method is to use the positive and negative rotation of the motor to realize the swinging action of the fish tail, so the utilization efficiency of the motor is low, which is not conducive to the high-speed swimming of the robotic fish

Abstract

The invention discloses a two-joint robotic fish driven by a single motor. The two-joint robotic fish comprises a C-shaped aluminum head, a control room and a push mechanism. The control room comprises a main control board, a lithium battery pack, a motor drive module, a direct current motor and a wireless communication module. The push mechanism comprises a first joint, a second joint, a Z-shaped connecting rod, an eccentric wheel, a sliding groove and a tail fin. The drive motor drives the eccentric wheel to rotate in a single direction, and through the position cooperative relationship between the first joint and the second joint, the high-speed swimming characteristic of the robotic fish is achieved. In addition, steering control over the biotic robotic fish is achieved through asymmetric rapid forward and reverse rotation of the motor. The biotic robotic fish is low in weight, small in size and simple in structural design, and the high swimming speed and the high maneuverability of the robotic fish can be achieved.

Description

technical field [0001] The invention relates to the technical field of bionic robotic fish, and more particularly to a two-joint robotic fish driven by a single motor. Background technique [0002] With the rapid development of bionic technology, as a machine system that imitates the swimming of fish, the bionic robotic fish is the product of the combination of bionics and electromechanics, showing very strong swimming performance, with high maneuverability, low disturbance, No pollution and so on. With the gradual deepening of research, the high-speed swimming of robotic fish has gradually attracted extensive attention of researchers. Faster swimming speed is of great significance for the robotic fish to complete underwater operations quickly and efficiently. [0003] In order to deeply understand the swimming mechanism of robotic fish and improve the swimming speed of robotic fish, scholars from various countries have done a lot of research work. In 2010, Jun Shintak et...
