Free Hardware projects that submerge or play with the liquid element are becoming more and more common, something interesting for many scenarios. But this project does not stop attracting attention and not only because it submerges but because It is shaped like a robot fish It is fully functional and for those with vision problems it can look like a normal fish, although you have to have vision problems to do so.
This robot fish is built by Eric Dirgahayu, the creator has built from plastic tubes a frame in the shape of a fish, a fish that has movable and retractable fins and tail that from a motor could operate e even move underwater. Inside the robot fish has a black box in which it is not only the Arduino Pro Mini board but also the connections with the servo motors and the servomotors that will move the robot fish created.
This robot fish is built with Arduino Pro Mini like many other projects
This project It is interesting although the truth is that the internal sealing of the robot fish does not allow the fish to dive into great depths but as a curiosity it is still interesting, as well as can serve as a foundation for new projects They may not have the shape of a robot fish but they do have the same essence and with Arduino Pro Mini as the brain of everything, a small and powerful board that is making many new projects work correctly.
This robot fish is a good example of the use that Arduino Pro Mini can have but there are other projects such as the noise meter or the home roomba. Now, are there more functions for this board or does it only work with small projects? What do you think?
