# Problem

Describe the problem you want to solve and motivate the need:
If an owner is away from home for vacation or away daily because of work, it can be hard to give the proper care for your pet. Solutions today are too one-dimensional when each pet requires different types of care even amongst the same species. Pets have unique and distinct preferences and the owner shouldn’t have to compromise because of the limitations of the feeder system.

# Solution

The solution to this problem is to design an automatic dispenser setup that delivers food and water to the user’s pet. Our solution will involve a couple of subsystems in order to provide users’ pets with the most comfort and care. The first and main subsystem will revolve around a pressure pad/sensor that will act as the main trigger for the dispensing system. The next subsystem is the dispensing of food and water, and all the features related to that.


# Solution Components

## Pressure Pad

Our main trigger system will be based on the pet’s weight. Our aim is to have the pet sit or walk onto a pressure sensor that will lead to food or water being dispensed.

Some features we are hoping to implement with this subsystem are:
Pressure pad being configurable to the pet’s weight (i.e., trigger weight for German Shepherd will be much higher than trigger weight for Chihuahua)
A camera that is activated after a set time of pressure on the pad that will take a photo of the pet and send it to the owner
Directly triggering the second subsystem to dispense food and water

## Dispenser Subsystem

This subsystem will center around our dispensing of food and water into our pet’s bowls. While this may seem simple in concept, we hope to incorporate features that raise the complexity of this subsystem.

Some features we are hoping to implement with this subsystem are:
Dispensing triggered by first subsystem
Amount of food and water dispensed will be calculated and can be combined with pressure sensors on the bowls to know how much food or water the pet has consumed
Dispensers will know when to stop filling bowl based on light sensors- this will also serve a dual purpose of not filling the bowl while the pet is consuming the food or water

## Bowl

This subsystem is mainly to send information to the dispenser system and communicate when dispensing should continue or stop.

Alerts the dispenser when to stop filling the bowl using load sensors
Vibration creator to create movement in the bowl for pet preference

## Mobile Application

This subsystem allows the owner to customize and set the dispenser settings to a highly customized level for their pet. The dispenser will be able to send data through the Raspberry Pi to the application, so the owner will be able to keep track of their pet and its well-being.

# Criterion For Success

1) We can categorize our goals by priority- focusing on fulfilling the most important features first]
2) Food and Water is dispensed when a pressure pad is triggered
3) The amount of food and water dispensed can be customized
4) The pressure pad sensor trigger weight can be configured
5) The amount of food and water dispensed can be calculated
6) The dispenser will stop dispensing regardless of the pressure pad trigger if the light sensor is triggered
7) Photo can be taken of pet after a set amount of time being triggered
8) Dispenser data is being sent to an external device.
9) The external device is able to set limitations to the dispenser.

Cypress Robot Kit

Featured Project

Cypress is looking to develop a robotic kit with the purpose of interesting the maker community in the PSOC and its potential. We will be developing a shield that will attach to a PSoC board that will interface to our motors and sensors. To make the shield, we will design our own PCB that will mount on the PSoC directly. The end product will be a remote controlled rover-like robot (through bluetooth) with sensors to achieve line following and obstacle avoidance.

The modules that we will implement:

- Motor Control: H-bridge and PWM control

- Bluetooth Control: Serial communication with PSoC BLE Module, and phone application

- Line Following System: IR sensors

- Obstacle Avoidance System: Ultrasonic sensor

Cypress wishes to use as many off-the-shelf products as possible in order to achieve a “kit-able” design for hobbyists. Building the robot will be a plug-and-play experience so that users can focus on exploring the capabilities of the PSoC.

Our robot will offer three modes which can be toggled through the app: a line following mode, an obstacle-avoiding mode, and a manual-control mode. In the manual-control mode, one will be able to control the motors with the app. In autonomous modes, the robot will be controlled based off of the input from the sensors.
