Why StemCell?

Affordable ESP32 hardware meets powerful AI. Build intelligent robots without expensive platforms or complex infrastructure.

Ultra Affordable

ESP32 robots cost just $10-20 in hardware. No expensive platforms, no per-robot fees. AI robotics for everyone.

Accessible to students and hobbyists

No Coding Required

Visual Blockly programming makes robotics accessible to everyone. Drag, drop, and build intelligent behaviors.

Perfect for education and beginners

Mobile-First

Control your robot from your smartphone. AI agent runs on your mobile device, calling Gemini API directly for intelligence.

No computer required, just your phone

How It Works

The Triad: Mobile-first architecture with edge computing

The Cloud

Sync Service Only

Lightweight backend that handles:

  • Bot configuration sync
  • Knowledge base distribution
  • Conversation backup
  • User authentication

Vercel + Neon PostgreSQL + AWS S3

The Nucleus

Mobile Edge Computer

Flutter app orchestrating everything:

  • Orchestrate ReAct loop on device
  • Call Gemini API directly (no backend)
  • Local SQLite for memory & context
  • Execute tools & control robot via BLE

Flutter + SQLite + BLE

The Body

Physical Robot

ESP32-powered hardware platform:

  • Motor control & sensors
  • BLE GATT communication
  • 10-30ms command latency
  • Safety & collision detection
