The home stretch is approaching. This week is dedicated to the organisation and description of the final project where I will describe step by step. Maybe later on I will make some changes if I have some problems or if I decide to change something.

My final project is an educational project for teaching and research. A control platform D.O.F Degrees of freedom "horizontal x". The degree of freedom can be thought of as the number of independent ways an object can move horizontally, from left to right or from front to back. It is ideal for introducing students to the fundamental and intermediate principles of controls. The university asked me to, so I can teach everything I learned to the students.

WHO HAS DONE WHAT BEFOREHAND?

I have been researching on the internet to see if there is anything similar to what I am going to do and I have not found anything.

The only thing I have found is a student project that does it vertically. Click here

So it will be good to have a first example of a machine with these characteristics and to be able to teach what I have learnt to the students.

CONSIST OF:

A support base to the structure, some fixing walls that have a hole where the fans will go.

Control the speed of the fans, they will move the ball on the "X axis" according to the power indicated on them.

The power of the fans will be controlled by a monitor that will be connected to the Arduino, one at each end for each fan.

A methacrylate cylinder where the fans will be connected at the ends. Inside the cylinder there is a ball that will move on the "X axis" according to the desired power of the fans.

The structure will be made of methacrylate about 10mm thick and I will make "pressfit" to be able to assemble the pieces so that they fit well. For this I will use the CNC milling machine. I will also place some hinges designed in 3D printer if necessary to better hold the base with the walls.

I will use the laser cutter to cut the cylinder to the length I need.

I will place vinyls to decorate the machine.

DESINGN TO BE REALISED

I am going to design the structure in methacrylate with the milling machine. I will use Solidworks to design it and then I will use the VCarve software to send it to the milling machine.

I will also make my own PCB with the Roland milling machine, where I will place a sensor and a screen among other components and then I will program it. I will use Eagle software to make the electronic schematic and then Dr. Engrave to send it to the Roland milling machine.

I will decorate my project with adhesive vinyl on the vinyl machine. I'll figure out how to make a design so it looks nice.

I will use the 3D printers. I will design parts like hinges to better hold the structure of the machine. I also plan to make a piece to hold the methacrylate tube with the walls of the structure, making the hole where the fans will be placed. Although I have another solution, but I'm still trying to decide.

The first problem I encountered was that: I have to attach the methacrylate tube to the structure of the machine with a piece to be able to hold it better. So I will design a suitable piece for it.

TECHNOLOGY TO BE USED:

CNC milling machine

3D printer

Vinyl cutting machine

Roland milling machine

HOW WILL IT BE EVALUATED?

A suitable code must be entered into the microcontroller for the fans to move and move the ball on the X axis with a sensor that identifies where the ball is located and a screen where we will see the values of the distance of the ball. The information is evaluated by sending information to the microcontroller and should move the fans. Knowing at all times where the ball is located.
