# Smart Medical Pill Dispenser (SMPD)

# Team Members:
- Aditya Perswal (apersw2)

- Aryan Moon (aryanm7)

# Problem
People often struggle with two major medication challenges. First, they forget to take their medications at the right time or take incorrect amounts. Second, they spend time sorting multiple medications into daily doses, which is both time-consuming and prone to errors. This is especially difficult for the elderly with multiple prescriptions they organize each week.

# Solution
An intelligent device that both sorts and dispenses medications automatically. Instead of manually organizing pills into compartments, users simply load entire medication bottles one at a time into the device. The system then automatically sorts these pills into correct daily doses and dispenses them at scheduled times. You can use a website connected to your device's ID and place in the times, dosages, and days you need to dispense medications and the SMPD will buzz at those times and on clicking dispense give you the correct dosages at once.

# Solution Components
## Subsystem 1
The RTC module provides precise timekeeping to dispense the medications according to schedule. It maintains accurate time even during power outages through its backup battery system. The module communicates with the microcontroller via I2C protocol to provide current-time data.
## Subsystem 2
The ESP8266 enables WiFi and remote management of the dispenser. It runs a web server that hosts the UI for medication management and provides real-time status updates. The module allows users to receive notifications. It processes HTTP requests for schedule updates and transmits dispenser status data to the cloud.
## Subsystem 3
The microcontroller drives the stepper motors that rotate the dispensing cylinder. It will make sure that the pills were dispensed at the right time (aka did you take your medication). The microcontroller activates buzzers or speakers for audible notifications and LEDs for visual alerts when it is time to take medication. Using ESP8266, the microcontroller connects to a web app to send reminders, allow remote monitoring, and enable users to adjust schedules.
## Subsystem 4
The weight sensor system uses load cells and an HX711 amplifier to measure medication quantities. It monitors the weight of each medication compartment to track pill counts and verify successful dispensing. The sensor data is used to detect when medications are running low and trigger refill alerts. This system also lets us dispense one pill at a time.
## Subsystem 5
The device housing and mechanical components are fabricated using food-safe PLA or PETG filament. The design includes separate sealed compartments for each medication type, a rotating dispensing mechanism, and channels for pill routing.
## Subsystem 6
The top of the device will consist of a funnel-like structure which will enable the user to dispense the pill bottles one at a time. The funnels will drop the pills into a jar to sort them into different placeholders. Once one kind of pill has been emptied, there will be a disk in place to rotate onto the next jar for the next pill to be dispensed into. To have the pills dispense properly we will have the top of the funnel open and close when it is ready to take in a new pill, additionally, it will rotate the pillars so that it is directly below the funnel, so we never lose pills in any sense.

# Criterion For Success
The following are all True/False evaluations

- The smart medical pill dispenser correctly buzzes at the right day and time
- The smart medical pill dispenser correctly dispenses the right medication with the correct dosage
- The smart medical pill dispenser automatically sorts the inputted bottles into separate compartments
- The smart medical pill dispenser appropriately alerts users when they need a refill by determining when certain medications are about to run out
- Cost of project to be $250 for end product and $5 for monthly server expenses

- Chuangy Zhang (czhan30)

- Jack (John) Casey (jpcasey2)

# Problem Components:

Keeping up with the high energy drive of some cats can often be overwhelming for owners who often choose these pets because of their low maintenance compared to other animals. There is an increasing number of cats being used for service and emotional support animals, and with this, there is a need for an interactive cat toy with greater accessibility.

1. Get cats the enrichment they need

1. Get cats to chase the “mouse” around

1. Get cats fascinated by the “mouse”

1. Keep cats busy

1. Fulfill the need for cats’ hunting behaviors

1. Interactive fun between the cat and cat owner

1. Solve the shortcomings of electronic-remote-control-mouses that are out in the market

## Comparison with existing products

- Hexbug Mouse Robotic Cat Toy: Battery endurance is very low; For hard floors only

- GiGwi Interactive Cat Toy Mouse: Does not work on the carpet; Not sensitive to cat touch; Battery endurance is very low; Can't control remotely

# Solution

A remote-controlled cat toy is a solution that allows more cat owners to get interactive playtime with their pets. With our design, there will be no need to get low to the ground to adjust it often as it will go over most floor surfaces and in any direction with help from a strong motor and servos that won’t break from wall or cat impact. To prevent damage to household objects it will have IR sensors and accelerometers for use in self-driving modes. The toy will be run and powered by a Bluetooth microcontroller and a strong rechargeable battery to ensure playtime for hours.

## Subsystem 1 - Infrared(IR) Sensors & Accelerometer sensor

- IR sensors work with radar technology and they both emit and receive Infrared radiation. This kind of sensor has been used widely to detect nearby objects. We will use the IR sensors to detect if the mouse is surrounded by any obstacles.

- An accelerometer sensor measures the acceleration of any object in its rest frame. This kind of sensor has been used widely to capture the intensity of physical activities. We will use this sensor to detect if cats are playing with the mouse.

## Subsystem 2 - Microcontroller(ESP32)

- ESP32 is a dual-core microcontroller with integrated Wi-Fi and Bluetooth. This MCU has 520 KB of SRAM, 34 programmable GPIOs, 802.11 Wi-Fi, Bluetooth v4.2, and much more. This powerful microcontroller enables us to develop more powerful software and hardware and provides a lot of flexibility compared to ATMegaxxx.

Components(TBD):

- Product: [https://www.digikey.com/en/products/detail/espressif-systems/ESP32-WROOM-32/8544298](url)

- Datasheet: [http://esp32.net](url)

## Subsystem 3 - App

- We will develop an App that can remotely control the mouse.

1. Control the mouse to either move forward, backward, left, or right.

1. Turn on / off / flashing the LED eyes of the mouse

1. keep the cat owner informed about the battery level of the mouse

1. Change “modes”: (a). keep running randomly without stopping; (b). the cat activates the mouse; (c). runs in cycles(runs, stops, runs, stops…) intermittently (mouse hesitates to get cat’s curiosity up); (d). Turn OFF (completely)

## Subsystem 4 - Motors and Servo

- To enable maneuverability in all directions, we are planning to use 1 servo and 2 motors to drive the robotic mouse. The servo is used to control the direction of the mouse. Wheels will be directly mounted onto motors via hubs.

Components(TBD):

- Metal Gear Motors: [https://www.adafruit.com/product/3802](url)

- L9110H H-Bridge Motor Driver: [https://www.adafruit.com/product/4489](url)

## Subsystem 5 - Power Management

- We are planning to use a high capacity (5 Ah - 10 Ah), 3.7 volts lithium polymer battery to enable the long-last usage of the robotic mouse. Also, we are using the USB lithium polymer ion charging circuit to charge the battery.

Components(TBD):

- Lithium Polymer Ion Battery: [https://www.adafruit.com/product/5035](url)

- USB Lithium Polymer Ion Charger: [https://www.adafruit.com/product/259](url)

# Criterion for Success

1. Can go on tile, wood, AND carpet and alternate

1. Is maneuverable in all directions(not just forward and backward)

1. Can be controlled via remote (App)

1. Has a “cat-attractor”(feathers, string, ribbon, inner catnip, etc.) either attached to it or drags it behind (attractive appearance for cats)

1. Eyes flash

1. Goes dormant when caught/touched by the cats (or when it bumps into something), reactivates (and changes direction) after a certain amount of time

1. all the “modes” worked as intended
