Modular by design, interoperable by default, and optimized for measurable ROI.

Embedded Edge Predictive ML Cloud Analytics Mobile Workflows APIs & ERP Security-first

🔧 1) VendCore Edge — Embedded Smart Controller

A lightweight, low-power retrofit kit that brings modern telemetry and control to existing machines without rip-and-replace. Designed for field installability and harsh environments.

  • Real-time fault detection: temperature drift, motor current spikes, coin/token mechanisms.
  • On-device inference: edge ML for early anomaly scoring and safe fallback modes.
  • Power optimization: sleep scheduling, component prioritization, compressor windows.
  • Wireless backhaul: Wi-Fi/LTE/Bluetooth with buffered retries for spotty links.
  • Open protocols: MQTT, Modbus, and vendor-neutral I/O for modular expansion.

🧠 2) VendCraft Predict™ — Predictive Maintenance Engine

An ensemble of time-series models (e.g., Random Forest features and LSTM sequences) that transforms raw telemetry into actionable maintenance decisions.

  • Degradation sensing: detects subtle drifts before hard failures.
  • Time-to-failure: estimates with confidence intervals to plan service windows.
  • Issue classification: coin jam, refrigeration fault, motor stall, door/lock anomaly, and more.
  • Continuous learning: models improve via anonymized field feedback loops.

📦 3) VendCraft Vision — Cloud Analytics & Dashboard

A centralized, secure web console for operators and managers.

  • 24/7 machine status, alerts, and usage metrics with drill-downs by region, model, or technician.
  • Real-time inventory tracking with refill urgency indicators and dynamic planograms.
  • Predictive KPIs: MTBF, refill window forecasts, downtime heatmaps, and performance scoring.
  • Built on scalable serverless primitives and hardened with AES-256 at rest and TLS in transit.

📲 4) RefillMate — Technician Mobile App

A field-ready mobile companion that keeps technicians aligned with real-time operations—even offline.

  • Smart refill alerts, inventory counts, and optimized routes.
  • Checklists, task tracking, and live issue resolution support with media uploads.
  • QR/barcode machine tagging for location verification.
  • Offline sync for rural/weak connectivity environments.

Tightly integrated with Vision for instant field-to-office coordination.

🔗 5) API & ERP Integration Suite

VendCraft plugs into your existing stack to reduce swivel-chair work and keep data flowing.

Fleet & ERP

Sync machines, sites, SKUs, and work orders with ERP/CRM platforms.

Logistics & Payments

Integrate route planners and payment reconciliation tools.

Voice diagnostics (optional)

OpenAI Whisper integration for hands-free, voice-based triage and notes.

🧩 System Architecture Overview

A modular, scalable, AI-first architecture that connects embedded edge devices with cloud analytics, mobile apps, and enterprise systems.

1) Edge Layer — VendCore

  • Collects telemetry: temperature, motor currents, coin jams, dispenses, door/lock events.
  • Executes lightweight ML for early fault prediction with safe fallbacks.
  • Sends data via MQTT over Wi-Fi/LTE/Bluetooth with retry and backoff.

2) Cloud Layer — Predict & Vision

  • Ingests and normalizes time-series streams in real-time.
  • Runs ML for predictive maintenance (LSTM & feature ensembles).
  • Stores inventory logs, fault history, and health indicators.
  • Exposes secure REST APIs and webhooks.

3) Application Layer — Vision & RefillMate

  • Dashboards for monitoring, analytics, and role-based control.
  • Technician app for routes, refills, checklists, and diagnostics.
  • Automatic alerts, performance scoring, and KPI tracking.

4) Integration Layer

  • Connects to logistics, ERP, CRM, and payment systems.
  • Supports enterprise sync, exports, and custom data contracts.
