OrionStar GreetingBot 2 – The New Generation AI Voice Interactive Robot Powered by AgentOS

The GreetingBot 2 is OrionStar‘s flagship full‑scene AI voice interactive service robot, representing a significant evolution from the GreetingBot Mini series. Built on OrionStar‘s self‑developed AgentOS operating system — which integrates industry‑leading large language models including DeepSeek, Doubao, and OrionStar‘s proprietary model — the GreetingBot 2 does far more than simply answer questions. It actively senses its environment, proactively initiates conversations, and intelligently guides visitors through complex spaces, delivering a truly warm and human‑centric interactive experience. Whether greeting visitors at a corporate reception desk, providing multilingual guided tours in museums and exhibition halls, handling inquiries and queuing at government service centers, navigating shoppers through retail malls, or guiding patients and offering companionship in hospitals and senior care facilities, the GreetingBot 2 performs like a seasoned “veteran employee” — always ready with accurate, professional answers.

Key Features

AgentOS — Active Perception and Proactive Service

Unlike traditional robotics operating systems that passively wait for commands, AgentOS enables the GreetingBot 2 to actively perceive, understand, and serve. It can greet visitors from 3–10 meters away, lead guests from 2 meters, and use visual recognition to detect a visitor‘s facial features and full posture — even offering personalized compliments. For returning visitors, it can remember their identity for a truly personalized experience. Importantly, AgentOS ensures the robot only responds when needed, politely stepping in without disrupting normal conversation, resulting in smarter, more emotionally intelligent interactions.

Mature and Stable Voice Interaction — 30+ Languages with Natural Human Voice

The GreetingBot 2 supports over 30 languages, with seamless switching across 9 languages during use, paired with highly natural, human‑like voice synthesis. Powered by a backend that integrates DeepSeek, Doubao, Qianwen, and OrionStar‘s proprietary large language models, the system delivers exceptionally stable voice interaction. Through a one‑click learning feature, the robot can rapidly master an enterprise‘s internal knowledge base, answering professional questions accurately and consistently across multi‑turn conversations — even handling complex sentences, fragmented expressions, and verbal slips by correctly interpreting user intent in context.

6‑Mic Circular Array — Superior Noise Handling and Far‑Field Voice Pickup

Equipped with a professional‑grade 6‑microphone circular array, the GreetingBot 2 achieves 360° omnidirectional sound source localization with an effective pickup range of 5 meters. Even in noisy environments up to 75dB, the system maintains recognition accuracy of over 92% in hands‑free mode, ensuring reliable voice interaction in busy commercial and public spaces.

14‑Inch HD Touchscreen with Intelligent Screen Orientation

The GreetingBot 2 features a 14‑inch 1080P ultra‑high‑definition touchscreen. During conversation, the screen automatically rotates toward the speaker, creating an intimate, face‑to‑face interaction that significantly enhances engagement. The display supports both touch and voice control, adapting seamlessly to different user preferences across various scenarios.

All‑Round Perception and Precision Navigation

The robot integrates a comprehensive multi‑sensor navigation suite: one LiDAR, three depth vision sensors, two fisheye cameras, two infrared cameras, odometry, and one IMU. This fusion system delivers 170° stereo + 240° panoramic coverage, enabling intelligent recognition of low obstacles and complex environments for fast, accurate obstacle avoidance. The robot supports standard mapping up to 5,000㎡ with centimeter‑level positioning accuracy.

• Narrowest passage width: 70 cm — easily navigates tight corridors and aisles

• Obstacle clearance: 1 cm thresholds and 3 cm grooves

• Incline capability: 5° slope

• Movement speed: 0.5–1.2 m/s (adjustable)

• Elevator integration: Supported for smooth, safe guidance across multi‑floor facilities

High-Performance Hardware Platform

Powered by a Qualcomm 8‑core chip paired with an industrial‑grade MCU, the GreetingBot 2 handles voice interaction, multi‑tasking, and complex AI processing with exceptional speed and stability. The dual architecture functions like a “brain + nervous system,” precisely coordinating motors and sensors for reliable operation even during peak‑hour reception or complex scenario demands. The robot is built from high‑strength aluminum alloy with industrial‑grade cable management, ensuring durability and reliability for long‑term deployment.

Extended Runtime and Intelligent Auto‑Recharging

The high‑efficiency battery system delivers 12–14 hours of continuous operation on a single charge, easily handling full‑day reception in high‑traffic scenarios. When battery levels run low, the robot automatically returns to its charging station for a 4.5‑hour recharge — no manual intervention required. Scheduled recharging support allows the robot to automatically replenish power during designated periods (such as lunch breaks or after closing hours), avoiding any disruption to peak‑time operations.

Dual Load Capacity for Enhanced Functionality

• Neck load space: 104mm × 80mm × 16mm

• Chest load space: 135mm × 129mm × 190mm

• Chest load capacity: 5 kg

This generous load capacity allows the GreetingBot 2 to accommodate functional accessories and signage attachments, enabling customized configurations for specific use cases.

Open Development and Flexible Expansion

The GreetingBot 2 provides open APIs and expansion interfaces for deep customization:

• Secondary development interfaces: USB‑A 2.0 ×2, USB‑C ×1, 100M Ethernet port ×1, DC 12V/3A output power ×1

• Easy integration with elevator controls, access control systems, and third‑party applications

• Seamless transition from application‑level SaaS to underlying PaaS for substantial reconfiguration capabilities

Global Multi‑network Compatibility

• Network support: 4G (TDD‑LTE, FDD‑LTE), Wi‑Fi (2.4GHz/5GHz), Ethernet

• Ready for global deployment out of the box

Enterprise‑Grade Service and Quality Assurance

OrionStar provides comprehensive after‑sales support to ensure long‑term reliability:

• Coverage: 200+ cities across China (international expansion available)

• Response: 2‑hour remote fault response, 24‑hour on‑site response for critical issues

• Reliability: 3‑year defect rate maintained above 95% for enterprise customers

• Resolution: Average 48‑hour fault closure; AI‑powered after‑sales tools enable customers to resolve 90% of minor issues independently
