For Developers

A Physical Input Device for Numbers

The Undugu abacus streams real-time bead-position events from 15 sensor-enabled rods. The SDK lets you build on that: new games, custom lessons, research instruments, accessibility tools — anything that benefits from hands on real beads.

Capabilities

What the Hardware Gives You

🎛️

Full Bead State

The exact position of all beads on all 15 rods, updated in real time — read the abacus value or track individual movements as events.

🔌

Flexible Connectivity

Connect over Bluetooth (BLE), Wi-Fi, or serial — from mobile apps, desktop software, browsers, or embedded systems.

🧩

Cross-Platform

The Undugu ecosystem runs on iOS, Android, Windows, Mac, and Chromebook — build once, reach students wherever they learn.

Ideas

What Would You Build?

  • Games — new practice games and multiplayer challenges on top of bead events
  • Lessons — custom curricula for your teaching method or language
  • Research — study fine-motor learning, numerical cognition, or embodied math with precise movement data
  • Accessibility — new interfaces for blind and low-vision learners, building on our blind-first platform
  • Integrations — connect abacus practice to your LMS, classroom tools, or tutoring platform

SDK access is currently by request while we work with early partners.
