13. Applications and implications

Assignment

Propose a final project masterpiece that integrates the range of units covered, answering: What will it do? Who’s done what beforehand? What will you design? What materials and components will be used? Where will come from? How much will they cost? What parts and systems will be made? What processes will be used? What questions need to be answered? How will it be evaluated? Your project should incorporate 2D and 3D design, additive and subtractive fabrication processes, electronics design and production, microcontroller interfacing and programming, system integration and packaging Where possible, you should make rather than buy the parts of your project Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable

Summary

This is my master piece is a where I will assembly not only parts but also use the knowledge learned during the course, cognitive strategies developed, cooperative and colaborative work done and feedback, as well as digital fabrication procedures and tech.

The project strategy turns out to be the accomplishement of several small self-closed tasks/projects, see the guidelines resume picture (just bellow).

The main purpose of this opensource unmanned robot solar catamaran boat is to be used as an affordable maritime platform for education and scientific research.

This page is organized by answering all the questions proposed in the Neil week 13 lecture.

Project Strategy

The first task to be accomplished is the safety electronic board that will control an inflatable bag it the catamaran hulls are flooded. This board will also control the lights as a function of the light level using the UV sensor that will also be used for the UV index. The temperature will be also measured inside each hull.

The next step will be hulls fabrication: in this part I will be using 3D printing interrelated with the sliced parts to make the support for the resin.

With all this assembled, I will mount the DC motors, the radio antenna and the PIXWACK board. NEXT: test it!

If I succeed in this part I will manage to use the GPS testing and the video streaming feature…

What will it do?

For now it will move controlled by radio with a safety system that will open and inflatable bag if the boat sink.

features

For the future it can carry a small underwater rover, chemical sea parameters sensors, sonar or any other devise.

Who’s done what beforehand?

This are the main readings of same professional and academic projects as well as commercial ptodcuts in the market.

What will you design?

The catamaran platform structure and the safety electronics, as well as the lights control, UV measure and motor control for the cage.

What materials and components will be used?

The boat should be 80% ecofriendly. I’m trying to accomplished that goal by using natural products and same ecofriendly resins that I’m searching for:

How much will they cost?

What parts and systems will be made?

Using this guideline Where possible, you should make rather than buy the parts of your project I decided to make the:

  • hulls;
  • boat safety electronics;
  • Control de motor

What processes will be used?

  • Molding and casting
  • 3D printing
  • 3D Slicer
  • 2D vector software design
  • Laser cutting
  • Electronics PCB design and fabrication -

What questions need to be answered?

  • Ecofriendly resins?
  • Will the resin adjust well to the PLA?
  • Will it float?
  • Could it be possible to use natural fibers and pine trees natural resins?
  • The CO_2 bottle is enought to inflate the bag?
  • The two motors are abble to gear the boat?

How will it be evaluated?

During the tests, the boat should:

  • Float;
  • be controlled at least by radio;
  • If it sinks the safety device should inflate;
  • Should be 80% ecofriendly;
  • It will measures UV light index and temperature;

All together now

This project does use 2D and 3D design, additive and subtractive fabrication processes, electronics design and production, microcontroller interfacing and programming, system integration and packaging

Cooperation

I have allready made a preliminary talk by skype with Remy since we have the same project goals. We are evaluating the type of collaboration we can make. For now we exchange knowledge base links.
