Its character, Yumemi, sees visitors through the camera of the screen, hears and speaks Japanese and English, and reacts to touch, all on the device itself. She finds faces on the GPU of the screen and follows them with her eyes, and she changes between four outfits in the colors of Coarobo, on a dark or a light stage.

Her senses and her tools appear as windows of light tied to her by threads, so she reads as an agent wired to her tools rather than as a character beside a menu. Turned on its side, the screen opens her workspace, where she presents the live data of the device and introduces Coarobo Heartbeat and OpenRoIS with codes that visitors scan with their phones.

Coarobo Heartbeat runs on the KTC MEGAPAD A32Q7 MAX, a 31.5-inch Android display, and is built with Unity on VRM 1.0, the avatar standard of the VRM Consortium. Its next phases connect it to robots and to other applications through OpenRoIS , the open-source middleware of the OMG RoIS Framework 2.0 that Coarobo GK launched in June 2026, so that Yumemi presents their data and operators speak through her.

Coarobo GK remains committed to lowering the technological barriers of robotics.
