Chronos Sentinel: Temporal Anomaly Bot

Inspired by the 'Map Locations' scraper project, the Chronos Sentinel doesn't just map static geography; it actively 'scrapes' its immediate environment over time, creating a dynamic 'map of moments.' Like the protagonist in '12 Monkeys' trying to piece together a fragmented past to prevent a future catastrophe, this robot continuously monitors its designated domestic zone, seeking -anomalies- in the sequence of events. It's programmed with a core 'Asimovian' directive: to -observe and report deviations from an expected safe or normal state- to its human operator, thereby indirectly ensuring human well-being and security.

Concept:
The Chronos Sentinel is a small, semi-autonomous robot designed to learn and maintain a 'temporal baseline' of a specific indoor area (e.g., a room, a workbench, a pet enclosure). It continuously monitors this space for any changes that deviate from its learned norm, logging these anomalies with timestamps and alerting the user. It's essentially a domestic historian looking for the 'butterfly effect' in your living space.

How It Works:
1. Hardware Assembly (Low-Cost & DIY-Friendly):
- Core Controller: A Raspberry Pi Zero 2 W or an ESP32-CAM module (for ultra-low budget). These provide sufficient processing power and Wi-Fi connectivity.
- Perception: A USB webcam or Raspberry Pi Camera Module. Optionally, a simple ultrasonic sensor (HC-SR04) for basic distance checks or a PIR sensor for motion detection.
- Mobility (Optional for basic version): A simple 2-wheeled robot chassis with two DC motors and a motor driver (e.g., L298N) allows the robot to patrol the area. For an even simpler build, it can be stationary, rotating a pan-tilt camera.
- Power: A small USB power bank or a standard 5V wall adapter.
2. Learning Phase (Building the 'Timeline Baseline'):
- Upon activation, the robot moves (or rotates its camera) through its designated area, capturing images and sensor data. The user can 'train' it by highlighting key objects, defining 'safe' zones, or marking expected positions of items (e.g., 'keys always on this hook,' 'door should be closed at night').
- Using simple computer vision (e.g., OpenCV), the robot establishes a visual and positional baseline: object identification, typical object locations, and environmental states (e.g., 'light off,' 'window closed'). This baseline forms its 'normal timeline' for the space.
3. Monitoring Phase (Detecting Anomalies):
- The robot continuously captures new images and sensor data.
- Anomaly Detection: It compares the current state against its learned baseline. Any significant deviation is flagged as an anomaly. This could include:
- Object Displacement: An object is moved from its usual spot (e.g., car keys missing, a book shelf reorganised).
- Unexpected Presence/Absence: A new object appears, or an expected object is missing (e.g., an unfamiliar package, a pet not in its bed).
- State Change: A door is open when it should be closed, a light is on, or a window is ajar.
- Temporal Discrepancy: An event occurs at an unusual time (e.g., motion detected in a usually empty room at 3 AM).
4. Reporting & Earning Potential:
- Temporal Logging: All detected events and anomalies are logged with timestamps, creating a detailed 'timeline' of the room's activities accessible via a simple web interface hosted on the Pi.
- Alert System: When a significant anomaly is detected (thresholds are customizable), the robot sends an immediate notification (e.g., email, Telegram message, push notification via a simple custom app) along with a snapshot or short video clip.
- High Earning Potential:
- DIY Kits & Pre-Built Units: Sell easy-to-assemble kits or pre-built 'Chronos Sentinel' robots with pre-flashed software, targeting hobbyists, elderly care, or pet owners.
- Subscription for Advanced Features: Offer a premium cloud-based service for enhanced AI analysis (e.g., differentiating between specific objects/pets, complex behavioral pattern recognition), long-term data storage, and integration with broader smart home ecosystems (e.g., 'if keys are missing, lock front door').
- Niche Software Modules: Develop and sell specialized software modules for specific use cases (e.g., 'Pet Escape Detector,' 'Elderly Fall Monitor,' 'Workshop Tool Locator,' 'Child Safety Zone Monitor').
- Anonymized Data Insights (with consent): Gather anonymized data on common domestic anomalies (e.g., frequently misplaced items, common times for unexpected movements) to sell insights to home insurance companies, smart appliance manufacturers, or home security firms, identifying common risks and patterns.
