The proyect we create uses an electromagnet to develop a boat / module coupler. In the passive position, six electromagnets can be found, which will function as a ladder to carry the active to its coupler. These electromagnets will generate an electromagnetic field that will pull the ship to dock. At the same time, it will have electromagnets of opposite polarity. In this way, the modules will attract each other. This will direct the module towards its final coupler. To make sure we don't have friction, the asset will have some bearings that will work as a slider. It will be useful because it will also avoid collisions. Once the module has arrived, the hooks on the coupler will release. These will aim to secure the capsule. The hooks will be actuated by a hydraulic system. Once the hooks are secure, you will proceed with connections such as hydraulics, electronic connections and pressurization of the coupler. These hooks are made of AISI 304 stainless steel chromed with Alodine 400, this will prevent corrosion. In the moving part of the shaft (bearing) there will be a thermal control to avoid damage (this thermal control will be used in all axes).

Decoupling system: This system works in reverse of the system coupler. The hooks will come loose, the magnetic poles will reverse. Therefore, the module will repel.

Safety system: If the automatic hook system fails, the safety system will remove the axle for them to release. This will have an external level that when activated will move the axes to one side and the hooks will be free.

 Advantage of this project: These modules will have the advantage of a better resistance in deformation such as bending and torsion, in addition they will have ease of coupling both in an automated and autonomous way, all this thanks to their conical shape and bearings.
