DIY Robotic Fish | Design and Assembly

This is a simple robotic fish made of a 4 - mini servo motor mechanism, Arduino Nano (ATMEGA328P), linear servo motor (for balance), Infrared Sensor eyes, small LiPo batteries, and a skin made of stretchy balloon material. The motion of the body (forward, left turn, right turn) is realistic and effective in water. The “eyes“ can detect obstacles in and out of water within a 10 cm range, and adjust to the natural sunlight in the environment. The skin/decoration turned out to be less successful, hence making the final robot somewhat weird. This video is just a simple guide to the process of designing and assembling this robot fish, and not a clear tutorial. For more content; Instagram: mcp - MicroController based Projects
