# Automatic Water Bottle Filler

# Problem

In normal liquid dispensing and water bottle filling systems, the process requires the user’s attention and constant manual activation of the device. This may require the holding of a button, the action of pushing the bottle against a sensor for a specific amount of time, or holding the bottle in front of a sensor until it is full. If the user gets distracted or is unable to provide that attention (blindness or lack of motor function), liquid may spill or the bottle may not be filled enough.

# Solution

Our goal with this project is to make an automatic water bottle filling station. Our device senses when a water bottle is placed underneath it, begins filling the bottle with water once a start button is pressed, determines when the bottle is full and shuts off automatically. After placing the bottle on a platform and pressing a button, the user can walk away knowing their bottle will be filled accurately.

# Solution Components
## Sensing Component

This subsystem utilizes multiple sensors including an ultrasonic sensor to measure the water level and a light-based sensor to determine the height of the bottle.

## Control

This subsystem connects the sensors to the water system. It receives data from the sensors, compares the water level height to the height of the water bottle, then decides to either begin, continue, or stop dispensing water.

## Display/Interface System

An LCD display will show instructions for the user and will display simple messages. A few push buttons will be included for manual filling and selection of desired amount of liquid (ex. Half bottle, full bottle)

## Water System

This subsystem utilizes a water tank attached to a pump and tubing, which transport water to the dispenser.


# Criterion for Success

The device…

- detects a water bottle and accurately measures the height
- monitors the water level in the bottle
- stops filling when a desired water level is reached

If there is no bottle/ the bottle is removed, the device stops filling water.

Featured Project

**Problem:** When working out at home, without a trainer, it’s hard to maintain good form. Working out without good form over time can lead to injury and strain.

**Solution:** A mat to use during at-home workouts that will give feedback on your form while you're performing a variety of bodyweight exercises (multiple pushup variations, squats, lunges,) by analyzing pressure distributions and placement.

**Solution Components:**

**Subsystem 1: Mat**

- This will be built using Velostat.

- The mat will receive pressure inputs from the user.

- Velostat is able to measure pressure because it is a piezoresistive material and the more it is compressed the lower the resistance becomes. By tracking pressure distribution it will be able to analyze certain aspects of the form and provide feedback.

- Additionally, it can assist in tracking reps for certain exercises.

- The mat would also use an ultrasonic range sensor. This would be used to track reps for exercises, such as pushups and squats, where the pressure placement on the mat may not change making it difficult for the pressure sensors to track.

- The mat will not be big enough to put both feet and hands on it. Instead when you are doing pushups you would just be putting your hands on it

**Subsystem 2: Power**

- Use a portable battery back to power the mat and data transmitter subsystems.

**Subsystem 3: Data transmitter**

- Information collected from the pressure sensors in the mat will be sent to the mobile app via Bluetooth. The data will be sent to the user’s phone so that we can help the user see if the exercise is being performed safely and correctly.

**Subsystem 4: Mobile App**

- When the user first gets the mat they will be asked to perform all the supported exercises and put it their height and weight in order to calibrate the mat.

- This is where the user would build their circuit of exercises and see feedback on their performance.

- How pressure will indicate good/bad form: in the case of squats, there would be two nonzero pressure readings and if the readings are not identical then we know the user is putting too much weight on one side. This indicates bad form. We will use similar comparisons for other moves

- The most important functions of this subsystem are to store the calibration data, give the user the ability to look at their performances, build out exercise circuits and set/get reminders to work out

**Criterion for Success**

- User Interface is clear and easy to use.

- Be able to accurately and consistently track the repetitions of each exercise.

- Sensors provide data that is detailed/accurate enough to create beneficial feedback for the user

**Challenges**

- Designing a circuit using velostat will be challenging because there are limited resources available that provide instruction on how to use it.

- We must also design a custom PCB that is able to store the sensor readings and transmit the data to the phone.
