Video: First-ever live unscripted conversation between humanoid robots

At CES 2026, Realbotix showcased a pioneering demonstration featuring two humanoid robots, Aria and David, engaging in the first-ever fully autonomous, unscripted conversation between physical humanoid robots. The dialogue lasted over two hours in real time without any human intervention, scripting, or teleoperation.

Visually, the robots appeared more like “rubber mannequins with speakers
