## Devpost submission (written by the team)

### Inspiration

I think the world forgets there are 500,000 people or more who cannot speak or move around. As an IT Support Specialist, I became a specialist at setting up their complicated, overbearing, unfriendly equipment and I thot this a perfect Hackathon to showcase a solution

### What it does

ASL Command allows you to use hand signals to control anything and communicate with AI and the world. We use Next.Js, Vapi, Claude and Gemini to provide this service and the connection to the world including phone, sms, lights and an arm that can bring you things.

### How we built it

I used lerobot and printed and assembled the arms then programmed them on datasets to recognize items and perform certain tasks then I made software that reads American Sign Language and fires tools, like Vapi, Claude or Lerobot, based on said Hand Signals.

### Challenges we ran into

Training is huge and crashed the repo, took me 3 hours to recover. Other than this, just a matter of time... takes time to train in all the hand signals and actions.

### Accomplishments we're proud of

It freaking works man. I don't care if we win if we are the inception of something that helps someone without arms or voice interact with the world and be happy. I am proud of that all day.

### What we learned

That I should have started two days early and found teammates to do the training while I was debugging. Hard for autistic synesthete to work with others... better to watch. :D

### What's next

for ASL Commander I want this for me... full house control by hand clapping, signals and other items that are FAR more effective than voice! (plus they don't interfere with my voice convo or listening to music)

### SETUP.md

```markdown
# ASL Command Center - Setup Guide

## Quick Start

1. **Run the start script**
   - On Windows: Double-click `start.bat`
   - On macOS/Linux: Run `./start.sh`

The script will automatically:
- Start a local web server
- Start the AI server (if llama.cpp is installed)
- Open the app in your browser

## Manual Installation

### 1. Install Python
- Download from [python.org](https://python.org)
- Make sure Python is added to your PATH

### 2. Install llama.cpp (Required for AI Features)

#### macOS
```bash
# Using Homebrew
brew install llama.cpp
```

#### Windows
1. Download the latest release from [llama.cpp releases](https://github.com/ggerganov/llama.cpp/releases)
2. Extract to a folder
3. Add the folder to your PATH

#### Build from Source
```bash
git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
mkdir build && cd build
cmake ..
cmake --build . --config Release
```

### 3. Start the Servers Manually

1. **Start the Web Server**
```bash
# From the project directory
python -m http.server 8000
```

2. **Start the AI Server**
```bash
llama-server \
  --hf-repo ggml-org/SmolVLM-500M-Instruct-GGUF \
  --hf-file smolvlm-500m-instruct-q4_k_m.gguf \
  --port 8080 \
  --host 0.0.0.0 \
  --n-gpu-layers 99 \
  --chat-template chatml
```

3. Open http://localhost:8000 in your browser

## Optional: Vapi Agent Ava Setup

1. Create a Vapi account at [vapi.ai](https://vapi.ai)
2. Create a new assistant
3. Copy your API key and Assistant ID
4. Configure these in the web app's localStorage or environment

## Robot Control Setup

For robot integration, ensure your robot control server is accessible at the configured endpoint.

## Troubleshooting

### AI Server Issues
- Ensure llama.cpp is installed and in your PATH
- Try running without GPU acceleration (remove --n-gpu-layers)
- Check server logs at http://localhost:8080/health

### Web Server Issues
- Make sure port 8000 is available
- Try a different port: `python -m http.server 8001`

### Camera Issues
- Ensure you're using HTTPS or localhost
- Grant camera permissions in your browser
- Try a different browser (Chrome recommended)

```
