# Electronic Page Turner

Team Members:

- Alyssa Bradshaw (akb5)

# Problem:

Page turning is required when reading a book. This is typically done with one's hands, which can be an inconvenience for those wishing to multitask while reading, such as playing an instrument or using a cookbook while cooking. This is a challenge for both avid readers and people with disabilities. There are hands-free page turners that exist, but most are expensive and typically designed for electronic reading on tablets.

# Solution:
The solution for this problem will use three different subsystems: actuation, sensors, and power. Our solution is unique because it is a hands free page turner for a physical book that can turn an unlimited number of pages.

# Solution Components:

## Actuation Subsystem:
- Stand with a Lever/Arm
- This would be controlled by servo motors to turn the pages
- Two would be needed to flip pages forward and backwards
- Adjustable levers to accommodate different sized books

## Power Subsystem:
- Uses batteries to power required subsystems and allow for portability

## Sensor Subsystem:
- Button (easy) Using a foot pedal to turn the page forward and backwards

_If we are able to meet the minimum requirements for success, we will try to implement the following bullet points:_

- Audio (medium) Using a microphone to turn pages forward when “Next” is said and backwards when “Back” is said
- Vision (hard)
Computer vision would be used alongside a camera to flip the page. It would be placed on the bottom left and right corners near the book and use some sort of facial cue in order to turn the page.

_If we are able to meet the minimum requirements for success, we will try to implement the following subsystem:_

## Processing Subsystem:
- A screen that displays the total pages flipped and how many pages were flipped in one sitting. This can help bookmark where you left off.
- Include a timer to keep track of how much time you have read i.e. if someone wants to read for 30 mins the device can make a sound letting the user know the time is up.


## Criterion for Success:
- A stand for the book with levers for turning pages in the book
- Has to be able to flip one page at a time, forward and backward
- Should be able to go through all the pages in a book
- Must be able to flip the pages using a foot pedal

# 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. Has a charge that lasts more than 10 min

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. Retains signal for at least 15 ft away

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
