Final Project¶
The problem¶
The raising of guinea pigs in the area of the mountains is very common, people also have their animals where they take them to graze in the field and return only in the afternoon where feeding these smaller animals is a bit complicated or they have to leave enough food or a person in charge but the food if it is left there is the probability that it will be contaminated with their feces. The inhabitants of the area also have other tasks and arrive at night to their homes. It is necessary to have a system that is automated to support the feeding of animals.
The idea¶
Regarding the project, the proposed solution to solve the problem is a mechanism that facilitates the process of feeding smaller animals such as guinea pigs automatically. It allows owners not to be physically present at their feeding but will inform them when the food and water run out. I will use this model as a reference of my project
Potential Final Project¶
The project consists of developing a portable house for guinea pigs with wheels where water and food will be installed and according to the animal it sees consuming, it will be registered with sensors so that it can be increased according to need. The data will be sent to a receiving device to keep track of everything in real time.
Componets¶
Next I will proceed to detail the necessary components for the elaboration of the cart.
Hardware / Mechanical pieces: * Electronics housing made out of acrylic. (Computer-Controlled Cutting) * Custom actuators and sensors housings. (3D Scanning and Printing) * Cart made out of plywood. (Computer-Controlled Machining)
Sensors (Input Devices):
Load cell: Integrated in the cart to register the weight of the collected products. Actuators (Output Devices): * LCD screen: Necessary to show all the information collected * Buzzer: Alarm for maximum weight reached or waypoint completed
Control board (Electronics Production):
Design of a board with all the inputs and outputs necessary to control the functions of the cart Extras: * Comunicación inalámbrica. (Redes y Comunicaciones) * Visualización de datos. (Interfaz y Programación de Aplicaciones)
To send the information collected by the sensors to a receiving device and display a graph and maintain constant monitoring to avoid the end of your food.
Final Project¶
About Cuy Wasi Peruvian guinea pig¶
What will it do?¶
In the guinea pig’s house there is an automated system that dispenses food as programmed, in this case 4 times a day to feed the animal.
Who’s done what beforehand?¶
In the academy, if there are dispensers, unlike mine, it is that it has 2 floors to house several animals, for example:
What will you design?¶
We will design the structure of the guinea pig’s house, design the animal’s feeder, and design the electronic board that, with the RP2040, performs the function of opening and dispensing the food.
What materials and components will be used?¶
Structure: - Guinea pig house: 3D design with onshape Guinea pig house with MDF. - Feeder: Design with Onshape and 3D Printing. - Card module: Onshape design and cutting with laser cutter. Electronics: - PCB: Copper clad Bakelite PCB. - 01 XIAO RP2040 - 01 USB-C - 01 servomotor - 01 pin header x4 - 01 pin header x3
Where will come from?¶
-
MDF materials for the structure were recycled and made from leftovers.
-
PLA filament.
-
The electronic components were purchased at a store in Pasco.
-
Xiao RP2040 microcontroller was imported from USA.
How much will they cost?¶
What parts and systems will be made?¶
The guinea pig house, the feeder were manufactured with 3D printing, and the PCB board
What processes will be used?¶
-
Computer controlled cutting
-
Desing assisted by computer
-
3d print
-
Electronic design
-
Electronic production
-
Embedded programming
-
Computer controlled machining
-
Output devices
-
Input devices
-
Communication & Networking
-
Programming of interfaces and applications
What questions need to be answered?¶
How long will the house made with MDF material last? How long will the cut of the acrylics that was used as a fence last?
How will it be evaluated?¶
It will be evaluated how much food it can handle per day to feed the animal and if it dispenses normally with the servomotor.
