# TARS

> **⚠️ Note to Visitors**
>
> This repository is a **personal fork** for experimenting with a new distributed architecture.
> If you're looking for the **main TARS-AI project**, please visit:
>
> 👉 **https://github.com/TARS-AI-Community/TARS-AI**
>
> This fork splits TARS into a dual-machine setup:
> - **Host Computer (macOS/Windows/Linux)**: Handles all AI processing (STT, TTS, LLM, Vision)
> - **Raspberry Pi 5**: Handles all hardware I/O (servos, camera, audio)

## Architecture Overview

**New Architecture:** RPi is self-contained and runs a WebRTC server + gRPC server. The host computer connects to it as a client.

```

**Key Principle:** The robot is self-contained. It boots up and waits for an AI brain to connect, not the other way around.

## 📦 Installation

### SDK Only (App Development)

For controlling TARS from your computer (Mac/Windows/Linux):

```bash
pip install tars-robot
```

This installs only the lightweight SDK (~3 dependencies) needed to connect to the robot via gRPC.

### Full Daemon (Raspberry Pi)

For running the robot daemon on the Pi:

```bash
pip install tars-robot[daemon]
```

This installs all dependencies including FastAPI, pygame, Adafruit libraries, etc.

## What This Repo Contains

- **gRPC-based control system** for Raspberry Pi 5 (low-latency hardware control)
- **WebRTC server** for bidirectional audio streaming
- **19 pre-programmed movements** for servo control
- **Camera capture via gRPC** (Pi Camera or USB webcam)
- **Real-time state synchronization** via WebRTC DataChannel

## Quick Start

### Web Dashboard

**First Boot WiFi Setup:**

On first boot, TARS starts a WiFi hotspot:
```
SSID: TARS-Setup
Password: tars1234
Setup URL: http://10.42.0.1:8080/setup
```

After WiFi is configured, access the dashboard at:
```
# Local network (home WiFi)
http://tars.local:8080

# Tailscale (dorm/corporate networks)
http://100.x.x.x:8080
```

📖 **[WiFi Setup Guide](./docs/WIFI_SETUP.md)** - Complete WiFi configuration instructions

**Dashboard Features:**
- Monitor robot status (battery, CPU, network)
- Control movements via joystick
- Install and manage apps from the App Store
- Configure WiFi and system settings

**Tabs:**
- **Status**: System metrics, battery, connections
- **Control**: Movement controls with joystick interface
- **Apps**: Official and community apps marketplace
- **Settings**: WiFi management, enterprise WiFi support, updates

### Command Line

Start the RPi daemon (waits for AI brain to connect):

```bash
# Start WebRTC + gRPC servers (default)
python tars_daemon.py

# Or using start script
./start.sh

# WebRTC only (no gRPC)
python tars_daemon.py --no-grpc

# Specify custom gRPC port
python tars_daemon.py --grpc-port 50052
```

The RPi will:
1. Start the WebRTC server on port 8001
2. Start the gRPC server on port 50051 (default)
3. Start the web dashboard on port 8080
4. Wait for the host computer to connect via POST /api/offer
5. Once connected, audio flows bidirectionally and gRPC handles hardware control
