OrionStar GreetingBot Mini – Compact AI Service Robot Master of Greeting and Leading

GreetingBot Mini is an intelligent, compact service robot specifically designed to optimize reception and guidance services in a wide range of commercial and public environments. With a minimal chassis diameter of just 55cm (21.6in), this robot is built to navigate tight spaces, elevators, and narrow aisles with ease—making it the ideal solution for enterprises and organizations seeking to modernize customer interactions without requiring major facility modifications.

GreetingBot Mini combines advanced voice interaction, HD visual capabilities, and autonomous navigation in a sleek yet sturdy frame. Whether greeting visitors at the front desk, guiding customers to meeting rooms, providing product information in retail stores, or delivering interactive experiences at exhibitions, this robot delivers consistent, professional, and engaging service 24/7.

Key Features

Large 14-Inch HD Touchscreen for Superior Visual Experience

Unlike many smaller display service robots, GreetingBot Mini features an impressive 14-inch full HD (1920×1080) interactive touchscreen that provides a more premium visual experience. The ultra‑high‑definition display ensures clear presentation of promotional content, wayfinding maps, product catalogs, and interactive menus, allowing businesses to effectively communicate with customers in an engaging manner.

Powerful Voice Interaction – 6-Microphone Circular Array

The robot’s head integrates an advanced 6-microphone circular array, delivering exceptional speech recognition accuracy exceeding 97% even in noisy environments up to 75dB. The system supports 360° full-field sound source localization with an effective far‑field interaction range of up to 5 meters. The robot actively detects people in its vicinity, initiates greetings, identifies the speaker‘s position, and rotates its head to maintain face‑to‑face conversation, creating a truly natural and personal interactive experience. The voice system supports 30+ languages, enabling global deployment out of the box.

Qualcomm Snapdragon Octa-Core CPU – Uncompromised Performance

As the world‘s first robot developed on the Qualcomm platform, GreetingBot Mini is powered by a Snapdragon octa‑core Kryo 385 CPU (2.8GHz × 4 + 1.8GHz × 4) – one of the most powerful SOC chips in the Android ecosystem – paired with an industrial‑grade MCU. This dual‑architecture design ensures smooth multi‑tasking, rapid response times, and reliable real‑time processing for complex AI workloads.

High-Fidelity Audio System – 30W Super Power with 5 Independent Sound Modules

Engineered by the same team behind Harman Kardon, the audio system features a 30W high‑power output distributed across 5 independent sound modules. The sound quality is comparable to a home theater system, delivering transparent treble, loud and clear midrange, and deep, resonant bass. Whether welcoming guests with a professional tone, playing background music during guided tours, or broadcasting promotional announcements, GreetingBot Mini‘s audio performance elevates any customer interaction.

HD Wide-Angle Dual Camera for Superior Visual Perception

GreetingBot Mini is equipped with a 13‑megapixel high‑definition wide‑angle dual camera system that delivers an ultra‑clear field of view with no blind spots. The light input exceeds that of a standard camera by 400%, providing enhanced night vision capabilities that ensure reliable remote video calling, security monitoring, and visual recognition even in low‑light conditions.

Autonomous Navigation – LiDAR + Depth Camera for Precision Mobility

At the base, a durable chassis incorporating LiDAR and a depth camera enables real‑time obstacle detection, simultaneous localization and mapping (SLAM), and dynamic path planning. The robot can operate at adjustable speeds between 0.5 and 1.2 m/s, gracefully navigating around obstacles without human intervention.

Autonomous Recharging & Extended Runtime

GreetingBot Mini operates for 10–12 hours on a full charge (approx. 4.5-hour charging time) and automatically returns to its charging dock when battery levels drop below 10%. This enables continuous 24/7 operation with minimal human supervision.

Multi-Robot Cooperation & Remote Management

When multiple GreetingBot Mini units operate in the same environment, an intelligent priority numbering system automatically coordinates their paths, ensuring collision‑free cooperation without manual intervention. An open development platform supports deep customization, while a cloud‑based management system enables remote monitoring, OTA updates, and fleet management across multiple locations.
