OrionStar GreetingBot Mini

OrionStar GreetingBot Mini is an MIDI generator tool. A compact wheeled reception robot with a 14-inch HD screen, six-mic voice interaction in noisy spaces, self-initiated greetings, guided leading and automatic recharging, aimed at lobbies, stores, hospitals and exhibition venues.

GreetingBot Mini is a wheeled service robot from OrionStar Robotics aimed at reception, retail and guided-visit work. It is the smaller sibling in the company's greeting line, and the design brief is narrow but practical: meet people at the door, start a conversation, show them something on screen, and walk them where they need to go. The hardware includes a 14-inch full HD panel (1920 x 1080), a 13 megapixel head camera, a six-microphone circular array with 360 degree sound source positioning, and a 30W audio system with five separate sound modules. The chassis is 410 mm square by 1000 mm tall, weighs 21 kg, and is built to pass through gaps as tight as 55 cm. The interaction model is proximity driven. The robot detects people nearby and initiates the greeting itself, rotating its head toward the speaker so the exchange happens face to face. Speech recognition is rated above 97 percent in ambient noise up to 75 dB, which is the figure that matters in a busy lobby or supermarket aisle. More than 30 languages are supported, and the screen is used both for conversation prompts and for advertising content in promotional mode. Navigation combines lidar with depth cameras, and the robot can lead a visitor to a destination while playing background music. When several units cross paths, priority numbering lets them resolve the situation without staff stepping in. Battery life is rated at 12 hours of typical cruising, with a charge time under 4.5 hours, and the robot returns to its dock on its own once power falls below 10 percent. Deployment scenarios listed by OrionStar are restaurants, supermarkets, hospitals, nursing homes, exhibitions and clubs, which describes the buyer fairly well: venues with steady foot traffic, a reception bottleneck and staff who cannot always leave the desk. An open development platform covers basic control, voice, vision and movement, plus an applet store for custom behaviors, so integrators can extend the stock reception flows rather than replace them. Compared with humanoid or larger promotional robots, GreetingBot Mini trades presence for maneuverability and screen real estate. It will not lift luggage or carry trays. It is a front-of-house greeter and wayfinder, and it should be evaluated as one.
