==Motivation==
 +
Our project inspired by the "Lego-powered Submarine" project from the Brick Experiment Channel. The core motivation of our project is to advance the capabilities of underwater exploration. We acknowledge the immense potential of underwater drones in scientific research, environmental monitoring, industrial applications, and education. Our project is driven by the need for cost-effective and versatile alternatives to traditional underwater exploration methods. We believe there is vast, untapped potential in underwater ecosystems, resources, and geological formations that current limitations and risks associated with human intervention prevent us from fully exploring.

A miniature underwater drone is a small remote-controlled device designed to operate underwater. These drones typically measure a few inches to a few feet in length, and they are equipped with sensors, and other tools to perform various tasks underwater. It may also have buoyancy control mechanisms to adjust its depth and maneuverability in the water. Miniature underwater drones can be used for a variety of purposes, including scientific research, underwater inspections, search and rescue operations, and recreational activities. Some miniature underwater drones are also designed to be compact and portable, making them ideal for travel and use in remote locations. They can be controlled by a remote controller, a smartphone app, or a computer, and some models can even be programmed to follow pre-defined routes or perform specific tasks autonomously.

You have an advantage that as engineers you know more about information theory and statistics than the average policeman or code breaking expert. You will take a structured approach to writing software code to use a process of elimination to say whether particular coding schemes were used or not.

:'''Note''' from Matthew: If you include the extra line, I'm not so sure you can prove it's not the Vigenère cipher. Also, given the date of the murder, and the dates of invention of some ciphers, there are some you could reasonably rule out (e.g. I doubt it's RSA for historical and technical reasons), however you can still implement them and try them out :). If you dig into some of the historical documents on the case you may find [http://xkcd.com/538/ clues to possible decryption keys].
