About Lightberry
Lightberry provides a social-control layer that connects language models with a robot’s microphones, speakers, sensors and action interfaces. The system listens to a person, maintains conversational context and can call approved robot skills such as gestures, movement or navigation. Configuration tools let an operator define personality, voice and permitted behaviours without programming every interaction sequence.
Robot manufacturers can integrate Lightberry with platforms including Unitree and Booster, while end users deploy the resulting agent for demonstrations, reception or other human-facing scenarios. The software mediates between open-ended conversation and the deterministic commands accepted by the robot, retaining limits around which physical actions may be invoked. Lightberry is an early Y Combinator company building interaction software for third-party humanoid bodies.
