Design and development of an Autonomous Underwater Vehicle (AUV) with fuzzy logic based controller
Autonomous underwater vehicles (AUVs) have become an integral part in helping humans do underwater explorations more efficiently and safely since these vehicles can stay underwater so much longer than any human can possibly do and they require little or almost no human interaction. These vehicles ar...

Autonomous underwater vehicles (AUVs) have become an integral part in helping humans do underwater explorations more efficiently and safely since these vehicles can stay underwater so much longer than any human can possibly do and they require little or almost no human interaction.
