Today, tilapia farming is a standardized and well-defined process, however, fish farmers do not have the necessary tools to ensure that the process is being carried out properly in terms of portions, especially when it comes to large ponds, feeding the school of fish in them becomes a task that requires time and effort. In this work, a project proposal was developed to help fish farmers with the design and construction of a prototype aquatic mobile automatic feeder that, as its name says, allows feeding the fish by moving around the pond and with the correct ratio. In addition, the design of a human-machine interface was developed so that the operator could control the prototype, including the ability to decide when to release the feed. This project is intended to help facilitate the fish farmer's task of feeding the school of fish using the mechatronic design methodology.
