# Problem

Frequent visits to the vet are rather expensive even with health insurance. Even with veterinary care, there is no other way for a pet owner to keep track of their pet's health and lifestyle. Metrics that give a better estimate of a pet' wellbeing such as heartrate, sleep hours, and calories burned are not available to pet owners at a low price yet.

# Solution
We propose to implement a wearable for pets that can be used by a pet owner when they wish to monitor their pet. This proposed device would consist of a harness-type wearable that could be adjusted to fit most small to medium sized dogs and cats. This harness would contain sensors for heartbeat data, GPS data and body temperature. We would process this data and present the user (pet-owner) with a range of metrics such as pulse rate, hours spent sleeping, calories burned and weather body temperature was normal or not. This would also help serve as an indicator for a pet's emotional stress levels. We propose to display the data in a user friendly phone-based interface with data transferred via bluetooth. The two main subsystems would be the sensing system on the harness and the processor.

# Solution Components
## Sensing subsystem
The sensing subsystem consists of each of the sensors mentioned above in strategic positions to maximize the accuracy of the readings for most animals of the size range of the product. We power the harness with a rechargeable battery, and expect to design the system to be light for pets' comfort. Data can be transferred via bluetooth or USB. We envision this device as something pet owners use to conduct periodic checkups on their pets, or during walks and play sessions. We would use a temperature sensor that would resemble this chip (https://store.siqma.com/max30205-human-body-temperature-sensor-module.html). Then we would have a GPS unit as seen in (https://www.alibaba.com/product-detail/Gps-Module-Lora-Gps-Module-Ebyte_62383600878.html?spm=a2700.7724857.normal_offer.d_title.7d216500dDQlLk&s=p). Finally, we have a heartbeat sensor (https://kuongshun.com/products/pulse-heart-rate-sensor). All these modules would output data to our PCB that would parse and send the data to our processing unit via bluetooth.


## Processing Subsystem

Here we would do math on the GPS data to determine distance covered and determine time spent sleeping. Additionally, we would process heartbeat data along with temperature data to make presentable to the user on the phone interface.

# Criterion For Success
- The harness unit collects data in real time and transmits data via bluetooth
- The user-end would present all the data in a well-organized UI
- The harness should be light and comfortable for the pet.
- Battery life is not an issue and there is an indication of that on the user interface

# Problem

WRSC (World Robotic Sailing Championship) is an autonomous sailing competition that aims at stimulating the development of autonomous marine robotics. In order to make autonomous sailing more accessible, some scholars have created a generic educational design. However, these models utilize expensive and scarce autopilot systems such as the Pixhawk Flight controller.

# Solution

The goal of this project is to make an affordable, user- friendly RC sailboat that can be used as a means of learning autonomous sailing on a smaller scale. The Autonomous Sailboat will have dual mode capability, allowing the operator to switch from manual to autonomous mode where the boat will maintain its current compass heading. The boat will transmit its sensor data back to base where the operator can use it to better the autonomous mode capability and keep track of the boat’s position in the water. Amateur sailors will benefit from the “return to base” functionality provided by the autonomous system.

# Solution Components

## On-board

### Sensors

Pixhawk - Connect GPS and compass sensors to microcontroller that allows for a stable state system within the autonomous mode. A shaft decoder that serves as a wind vane sensor that we plan to attach to the head of the mast to detect wind direction and speed. A compass/accelerometer sensor and GPS to detect the position of the boat and direction of travel.

### Actuators

2 servos - one winch servo that controls the orientation of the mainsail and one that controls that orientation of the rudder

### Communication devices

5 channel 2.4 GHz receiver - A receiver that will be used to select autonomous or manual mode and will trigger orders when in manual mode.

5 channel 2.4 GHz transmitter - A transmitter that will have the ability to switch between autonomous and manual mode. It will also transfer servos movements when in manual mode.

### Power

LiPo battery

## Ground control

Microcontroller - A microcontroller that records sensor output and servo settings for radio control and autonomous modes. Software on microcontroller processes the sensor input and determines the optimum rudder and sail winch servo settings needed to maintain a prescribed course for the given wind direction.

# Criterion For Success

1. Implement dual mode capability

2. Boat can maintain a given compass heading after being switched to autonomous mode and incorporates a “return to base” feature that returns the sailboat back to its starting position

3. Boat can record and transmit servo, sensor, and position data back to base
