#Bio-Inspired Robotic Fish

Project Overview

This project involves the design and development of a bio-inspired robotic fish, capable of mimicking natural fish movements for propulsion and buoyancy control. The fish tail uses a tendon-based mechanism to create a realistic left-right swimming motion, while a motor-controlled syringe adjusts buoyancy, allowing the fish to sink and rise in water.

Key Features

• Nested Conical Structure: A series of tapered cones connected at a single pivot point allows for smooth, flexible tail movement.
• Tendon-Based Mechanism: Servo motors control tendons that generate fish-like swimming dynamics by rotating the conical sections.
• Buoyancy Control: A motorized syringe changes internal fluid levels to regulate buoyancy, enabling the fish to precisely control its depth.

Components

• 3D Printed Tail Segments: Designed to taper and fit within each other, ensuring efficient motion.
• Servo Motor System: Provides actuation for the tendon mechanism, enabling left and right tail flexing.
• Motor-Controlled Syringe: Adjusts buoyancy by injecting or removing water from an internal reservoir.
