11. Applications and implications¶

This week I worked on defining my final project idea and started to getting used to the documentation process.

Propose a final project masterpiece that integrates the range of units covered
- Answering this questions :
  - 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?
The project Should containe some skills that i’ve learned during the fab academy journey:
- 2D and 3D design.
- Additive and subtractive fabrication processes.
- Electronics design and production.
- Embedded microcontroller interfacing and programming.

My emergency robot mission is to enter in the places in where the rescue team can not , to collect data and to discover if there is anybody in the accident place , through the ultrasonic and PIR sensors and as an additional equipement an fpv camera to add more
precision for the team to hear and see what is going in that place.

In fab academy I didn’t find someone who had done this before as well as in my country Tunisia but, in other place there isbut not with the same mission.
My Project design was inspired from some existing works here I add the links to it:

I will design almost every thing from the robot board until the whole shape.
I will design all the weels for my robots, including gears and the main shape, as well as the chain to hold the weels from moving and to insure the good move of the robot also the brushless motors holders in the main body. I am thinking to add an FPV camera Ultrasonic sensor and a buzzer so designing a Holder to carry them is what im going to do.
At the end, for the plexi cover to protect the interior componants I will design two holders to fix it from moving,

### Q3, Q4 AND Q5: What materials and components will be used?, Where will come from? and How much will they cost?

I will design the whole shape and the board.
I will design the main body to hold the other componants in it, as well as all weels, brushless holders, gears, cover and its holders and the chain to hold on the weels from moving.
I will use the 3D Printer to print those parts with the laser cutter to cut the cover also for the Ultrasonic sensor, buzzer and FPV camera holder.
To control the robot, I will use My friend self made controller in stand of buying an expensive one, and I will apply some modification on it so I can controle my robot. The modification will be adding an HC-12 device in stand of NRF 24.after that I will write a code to communicate the two controller potentiometers with the robot weels(brushless motors) also the code for the Ultrasonic and buzzer devices.

The design is looks good for the viewer.
The whole system is working well ( the output ,the input sensors and the networking and communication between the remote controller and the robot ( the two nrf’s 24 ) ).
