Applications and Implications

This week assignment was supposed to do 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?

What will it do?

A solar tracker with unique design and compact in shape having panels mounted in sunflower petal shape which open up with dual axis motion in order to track the sun in both east to west and north to south direction.

Final Project Animation

Who's done what beforehand?

There are lot of people that's done this type of projects before.. My one of the Inspiration for this was by seeing the by this leading company
SUNFLOWER SOLAR TRACKER

What will you design?

The physical sunlower tracker design.
The electronics to connect sensors to the tracker.

What materials and components will be used?

3D printing in PLA for the shape of the petals.
Lasercutting acrylic for the enclosure that holds the petals.
FR1 Copper material to create the PCB for Input and Output Device.
Sensors:

4 LDR.

LED
6*5.5V Solar Panel Polycrystalline Silicon
2 Servo Motors
1 Stepper Motor
Wire cables.
Main board:

Microcontroller: ATMega328P.

Where will they come from?

Most of the components we have at the Fab Lab, but others are going to be ordered online .

How much will they cost?

This is the Bill of Material for the project

1. 4 LDR = Rs 60
2. 6 Solar Panel = Rs 800
3. 3 Motors = Rs 1200
4. 1 Battery = Rs 100
5. 1 LED strip = Rs 100

What parts and systems will be made?

Main microcontroller board where all the sensors will connect. Mill and solder all the components.

Lasercut the acrylic panel where the sensors will conect.

3D print the shape of the sunflower.

What processes will be used?

3d printing, Computer Aided Design, lasercutting, electronics design and production, interface programming.

What questions need to be answered?

The design and mechanism for the petals to open up easily in 360 span.
The placement of the LDR sensor to make it attractive product.
Also the placement of the cicuit boards with the help of a 3d Printed component.

How will it be evaluated?

Testing all the connections, networking and communication.Design and mechanism of the dual axis solar panel for motion up and down, left and right.

Gant Chart

I have prepared a GANTT Chart according to the deadline for assignments that is given to us to complete the documentation.Due to covid pandemic we have presented final project presentation first and after that completed the remaining assignments.The data is according to covid situation.
