What tasks have been completed, and what tasks remain?

Completed Tasks:

• CAD design of the casing.
• Manufacture of casing with laser cut cardboard.
• Manufacture of resin composites with fabric
• Manufacture of PCB with the microcontroller and step response
• Manufacture of PCB of the driver for the stepper motor
• Printing in FDM and LFS of the parts

Remaining Tasks:

• Design a web app that interfaces with the device.

What has worked? what hasn't?

• A notable difference is observed in the step response signal reading when adding or removing cookies.
• You can read the percentage of container filling with the Time of Flight light sensor.
• The food is moved with the actuator to deposit it on the food plate.
• The scrolling speed of the cookies is slow so that can be improved.
• The data read can only be observed through the serial port, an interface must be added.

What questions need to be resolved?

• Why the step response is decalibrated if the food plate is changed position.
• How would I make the casing have a better finish

What will happen when?

The project will be exhibited on June 12, after this presentation the remaining documentation will be worked on until the closing of the diploma course.

What have you learned?

There are many skills that I have been able to learn developing this final project, the one that surprised me the most was composites since I was able to convert cardboard that can be brittle into a completely solid structure, I have also been able to improve my knowledge in 3D printing, especially in the use of resin that allows us to create objects of better resolution. Regarding electronics, the use of step response seemed quite versatile for different applications in the case of this project to evaluate the weight of the object on the electrodes.
