PRODUCT — ROBOT × AI SOLUTION

A Japanese-grade body,
a Taiwan-built brain.

The finest body is useless without a brain to run it. On one side, a Japanese-made robot body; on the other, the AI brain built by Sigma. Take either part on its own — or let’s work out together how it deploys at your site.

Two parts, side by side

Sigma (Σ) stands for integration — AI on a robot body, integrating a working solution into your site

AI APPLICATION LAYER — BUILT BY SIGMA
See. Answer. Write. Act.

Visual inspection, bedside vital signs, button-call dispatch, smart reception — four capabilities on one platform.

HARDWARE LAYER — PREFERRED ROBOTICS KACHAKA PRO
A Japanese-built chassis. Best-in-class navigation.
