Design and manufacture of Bio-mimic robotic fish

Abstract

Design and manufacture an underwater robot by using bio-mimic design approach for the application of surveillance. The design, development, graphical modelling and control of a bio-mimic underwater robot named the Robotic Fish has been presented in this report. The simple and efficient design is inspired from Mother Nature. This robot not only navigates in an underwater environment on its own but also operates efficiently with simple mechanism consisting of two servo motors and a pump assembly. Servo motors enable to obtain swift forward and rotational motion and pump assembly assists deep diving in water. Various sensors help the robot to make intelligent decisions such as obstacle detection, change in direction and also provide valuable information as live streaming, pressure and temperature. The innovative design of robot helps to reduce the complex structure without compromising the agility and performance of the robot which helps to achieve the real motion of the fish, making robot competent for aquatic-based applications such as underwater exploration, oceanic supervision, detection of pollution level and military detection.
