SIGMA AI SOLUTION

Our algorithms —
a robot that takes on harder work.

More than fetch-and-carry. We put advanced AI on autonomous mobile robots — heavy reasoning in the cloud, low-latency calls on the edge — and fuse every sensor into one decision, turning a traditional AMR into something new and genuinely useful. For the body that carries it, see the robot →.

Cloud and edge — the right model in the right place

Heavy inference in the cloud, low-latency on the edge — run the right model where it belongs

Visual inspection
Heavy models reason in the cloud, the robot reacts on site

Photographs and inspects fire extinguishers, AEDs, fire doors and lighting point by point, adaptively learning what "normal" looks like on site, pushing anomalies to Telegram/LINE and auto-generating illustrated inspection reports.

Button call × offline routes
Runs entirely on the edge — even offline

Physical-button call, multi-stop route scripts running on the robot itself, shake the body to send it to the next stop — built for sites with poor connectivity.

Smart reception
Cloud voice, natural-language interaction

Greeting, wayfinding and real-time voice Q&A (Chinese, English, Japanese) — hand the routine questions at your entrance to the robot.

Fuse every sensor into the decision

Cameras, vital-sign sensors, ToF... into one judgment

Bedside vitals
Multi-sensor fusion; night rounds without lights, without waking anyone

Contactless vital-sign collection, combining cameras and multiple sensors, scheduled rounds, anomaly alerts to the nurses' station, CSV export; interpretation and intervention remain with nursing staff.

Integrate the sensors you have
Turn sensor signals into judgment

On-board cameras and ToF, add-on vital sensors, third-party sensors — fused into one decision pipeline so the robot acts on what's actually happening on site.

We're looking for...

Whichever end you're on, we connect

AMR makers

Have the chassis, want the AI

We integrate our algorithms and sensing onto your robot, giving existing models new capabilities.

End sites

Have the pain, want a robot

We develop and deploy to your site — survey, rollout and go-live, all in one hand.

System integrators

Want to build on top

Open API, SDK, MCP and skills; open-source apps — take them and grow your own.

For developers and partners: built on the robot's open architecture, we wrote the MCP server, skills and SDK toolkit (kachaka-sdk-toolkit) to speed up partner development, and open-sourced every application — Visual Patrol, Bio-Patrol, Kachaka-Gemini, and more, all on our GitHub. Join us and build more robot applications together.
