IntBot bets the future of humanoids on social intelligence, not kung fu
While most humanoid startups pour resources into better walking and grasping, IntBot Inc. is betting that the harder problem is teaching robots how to behave in a crowded hotel lobby.
The Sunnyvale-based startup has deployed its Nilo humanoid as a multilingual concierge at three U.S. hotels: The Nap York in New York City, Otonomous in Las Vegas, and a Marriott in Tulsa, Oklahoma. All three operate 24/7 alongside human staff members.
"We already have three hotels across the U.S.," CEO Lei Yang told The Robot Report at GTC 2026. "All of these three robots operate 24/7, basically. They work alongside their human staff members, but IntBot offers add-on functions to augment what the human staff, concierge, or other people can do."
IntBot's approach is deliberately hardware-agnostic. Rather than building its own robot body, the company has developed IntEngine, a multimodal social intelligence system that fuses vision, audio, and language in real time to coordinate speech, facial expression, and gesture. The stack runs on off-the-shelf hardware and can be deployed across different robot platforms.
At GTC, IntBot also showcased the first edge deployment of NVIDIA's Cosmos Reason-2 vision-language model within its software stack, enabling real-time scene understanding in complex environments like crowded conference floors.
Yang's pitch is that mastering natural, multi-party interaction is what will determine whether humanoids get accepted as everyday co-workers or remain trade-show curiosities. "The first-generation robot was pre-programmed action," he said. "But for our robot, all the emotions are generated. Even if you're not talking to the robot, it would respond with very natural, very subtle motion — just the very side nodding to show 'Okay, I'm listening,' or the kind of motion to indicate 'I'm alive.' Everything is driven by our social intelligence."
It's a contrarian bet in an industry obsessed with hardware specs. Whether it pays off depends on whether hotels — and the public — actually want humanoid concierges, or just better ones.
