The X-Humanoid Tian Yi 2.0 is a wheeled-arm humanoid service robot designed for research and reception. It provides reception guiding and tour explanation services with low-latency voice interaction, generalized Q&A based on customer knowledge bases with sub-second response, and an emotional large model that recognizes user actions and expressions to proactively initiate interaction with full-body motion responses. For patrol inspection, it combines multimodal perception with embodied operation capabilities using visible light and thermal infrared recognition, with custom item identification via large model. It autonomously operates elevators using VLA end-to-end large model for button pressing and card swiping without facility modifications, plus item transport, button operation, and cabinet door opening. A single hardware platform supports multiple functions such as night patrol and daytime reception through different software modules. Remote operation via VR or cockpit supports one operator managing multiple robots. Targets research and reception applications.
