FINAL_PROJECT

PROJECT DEVELOPMENT

WEEK 00

Task:

complete your final project, tracking your progress:

what tasks have been completed, and what tasks remain?

what has worked? what hasn't?

what questions need to be resolved?

what will happen when?

what have you learned?

documentation during development

demand- vs supply-side time management

spiral development

Fabrication

The first idea consists in using gears to drive the servo motors and allow movement of the parts.

But when operating the gear generates pressure on the other parties. So I need to change the design or make safety each parts with structure.

The second idea design based in train mechanist, now change the design concept allows pieces are secure , with the respective support and a structure for easy placement of the booster, this module is repeated 16 times.

Each parts of the modules places ready for be cut by laser in format of the work place

Componets

Manufacturing

Acrylic laser cut parts
16 Servo motors

Componets

Electronics

16 servomotors
16 photoresistor solded with resistor of 10k
16 LEDs solded with resistor of 220 ohm

3 fabduinos for send signal to the output and input

For the final project I made my own protoboard for connect all the servos, with GND and VCC. All the pins are connected to a power supply of 5V.

GND

VCC

SIGNAL

This is the case for save the the boards and hide all the wire

Assembly

The assembly is per module and then all the structure that union each part
The assembly took me several hours since I returned to redesign the modules to let the servomotor adjusted without any screw strain

Programming

The programming based on passing the hand over a input(LDR ), action servomotors rotate 45 degrees, and each time the LDR receives less light drives the servo to reach 180 degrees this translate into increasingly that rotates , the piston rises 3 centimeters. At the same time it causes an ignition sequence of the LEDs are activated.

The programming test is not working perfect because when I touch the LDR , the servomotor move, but I don't want it return up to 180 degrees.

Design

Task:

what tasks have been completed, and what tasks remain?

Assembly and programming
Make a case for the wires

what has worked? what hasn't?

The fabduino board and protoboard work perfect
Some servomotor get freeze

what questions need to be resolved?

How to make wireless? Its necessary 8 wires per module?
How can I improve the design?
How can I improve the programming ?

what will happen when?

I need to improve my skill design

what have you learned?

Make press fit design without glue
Optimization design
Read code
Write code and programming
