## Inspiration

Due to our craze for space exploration, we are forgetting how we are polluting outer space and the long-lasting changes that we are making. Just like climate change, we will soon have space change.

Due to our today's mistakes, I do not want our future generations to take charge of cleaning space just so a spacecraft or a satellite can fly to the moon or elsewhere in the galaxy. We need a better mechanism to tackle this man-made mess that we have created in space.

**The rate at which these tiny space debris move in space has the capacity of destroying an entire satellite and spacecraft. Detecting Space debris is the need of the hour and we need to work on it ASAP before it gets too late for mankind to do space exploration because there is too much *GARBAGE IN SPACE*!**

## What it does

The Solution that I would like to propose is in the following three steps:

1. Can we use Radar as a Payload on a Cubesat that can detect debris of size 1-15 cm? Challenging, but yes we can!
2. Can we design a very High Gain Foldable Antenna into this CubeSat? Challenging, but yes we can!
3. Can we deorbit debris by using a Gun-shoot in Space? Challenging, but yes we can!

## How we built it

The following steps need to be followed as per the below priority

1. Calculate radar equation
2. Calculate antenna parameters
3. Deign the deployment mechanism for the antenna into the CubeSat
4. Design its overall system
5. Design its electrical design
6. Design its mechanical design
7. Design the estimate of how the projectile can hit the debris and deorbit it
8. Build the CubeSat and work on how it will not be potential debris in space

## Challenges we ran into

Estimating how the radar can detect debris in space and simultaneously also be able to deploy a very large antenna into a very tiny CubeSat. The building of this CubeSat can take us at least 4-5 years.

## Accomplishments that we're proud of

I am really very confident that this will soon be a successful mission. Additionally, I am also very proud that although this system needs a little modification over time, I was still able to personally establish that this system can practically be deployed into space by taking help from my professors at Stanford as well from friends in the Spacecraft design class that I am taking at Stanford as an Electrical Engineering student. Proud of what I have been able to do so far!!! :)

## What we learned

How to determine if the radar can be designed, design the very high gain antenna and establish that the projectile can be used to hit the debris

## What's next for PIERCE

Working on building all the models that are mentioned under how we build it.
## intelliTrash

**Inspiration and What it does**
intelliTrash is an automated waste machine which uses vision AI to be able to determine, and sort trash into either recycling, compost, or garbage. This idea was hatched when a teammate found out that a family friend had been disposing of used diapers in recycling, after mistaking a symbol on a recycling poster for a diaper. Another teammate then suggested we use Google's Vision API to be able to detect and categorize certain types of trash. Eventually we came to the conclusion that incorporating automated parts, vision AI, and IoT would allow us to bring our project to life!

**How we built it**
For the hardware component of our hack, we used various GPIO pins on the Raspberry Pi to read out to the push button, and two servos, while using the built in attachment for the Pi Cam. We also built a physical system out of wood, which allows intelliTrash to be automated, and deliver the trash into it's designated bin. After the Pi Cam takes an image, and we used Google Cloud's Vision API to identify what the waste is and where it belongs. Afterwards, our program will rotate the servo motors. Each specific type of rubbish corresponds to a specific angle which the motors turn to. This allows the system to "sort" the trash into Recycling, Compost or Garbage.

**Challenges we ran into**
We learned quite a few things on this journey. Initially, our team struggled trying to connect the Pi to the "UofT" network, as it is considered a hidden network- meaning the Pi doesn't seem to like it. Instead, we ended up using a team member's personal LTE network to hotspot the Pi.
We also had initially planned a conveyor system to sort the trash, as opposed to the "rotating" system we have now. We learned that the servos would not be able to support the weight of trash put onto a conveyor. Our team then ventured out, and bought two DC motors. After working for a while, we realized that the DC motors were also incredibly weak. We then needed to change the system in a way, which does not conflict with the physical capabilities of of the servo motors- which is how our "rotating" system was born!

**Accomplishments that we are proud of**
Our team feels incredibly accomplished for being able to work together through these constraints, and be able to create a project which we are all incredibly passionate about in such a limited timeframe. We are also proud that we were all able to come from such different backgrounds and use that as a motive to create a project which encompasses all of our strengths, but also taught us how to work around our weaknesses!

**What's next for intelliTrash**
Next we want to be able to identify the type of plastics to be able to sort it into even more categories such as Plastics, Mixed Paper, Coffee Cups and more. Additionally we would like to use the city location to adhere to their waste rules.
## Inspiration

Studies show that drawing, coloring, and other art-making activities can help people express themselves artistically and explore their art's psychological and emotional undertones [1]. Before this project, many members of our team had already caught on to the stress-relieving capabilities of art-centered events, especially when they involved cooperative interaction. We realized that we could apply this concept in a virtual setting in order to make stress-relieving art events accessible to those who are homeschooled, socially-anxious, unable to purchase art materials, or otherwise unable to access these groups in real life. Furthermore, virtual reality provides an open sandbox suited exactly to the needs of a stressed person that wants to relieve their emotional buildup. Creating art in a therapeutic environment not only reduces stress, depression, and anxiety in teens and young adults, but it is also rooted in spiritual expression and analysis [2]. We envision an **online community where people can creatively express their feelings, find healing, and connect with others through the creative process of making art in Virtual Reality.**

## What it does

We built a VR application that **learns from the user's subjective survey responses** and then **connects them with a support group who might share some common interests and worries.** Within the virtual reality environment, they can **interact with others through anonymous avatars, see others' drawings in the same settings, and improve their well-being by interacting with others in a liberating environment.** To build the community outside of VR, there is an accompanying social media website allowing users to share their creative drawings with others.

## How we built it

* We used SteamVR with the HTC Vive HMD and Oculus HMD, as well as Unity to build the interactive environments and develop the softwares' functionality.
* The website was built with Firebase, Node.js, React, Redux, and Material UI.

## Challenges we ran into

* Displaying drawing real-time on a server-side, rather than client-side output posed a difficulty due to the restraints on broadcasting point-based cloud data through Photon. Within the timeframe of YHack, we were able to build the game that connects multiple players and allows them to see each other's avatars. We also encountered difficulties with some of the algorithmic costs of the original line-drawing methods we attempted to use.
