Lightberry OS is the proprietary operating system of the Lumi social robot developed by Lightberry, based in San Francisco. It is a custom Linux distribution running on the robot's onboard computer, integrating perception, navigation, control, and voice/conversational interaction into a single software stack.
The system runs a hybrid local-cloud model. The onboard layer handles perceiving the environment, navigation, and taking actions, while Lightberry's cloud-based agent provides communication understanding and high-level task planning.
Lightberry OS is a custom Linux build based on NVIDIA Jetson Linux 39.2, running on the NVIDIA Jetson Thor T4000 module. Stated components include Linux kernel 6.8.12, glibc 2.28, GCC 13.2.0, CUDA 13.2.1, cuDNN 9.20.0, and TensorRT 10.16.2.
Functionality can be extended through extensions running directly inside the OS or in containers. The SDK exposes an interface for Python and Rust, and inter-process communication is handled via shared memory using iceoryx2.
General-purpose or robotics-specialized operating system — Ubuntu, Ubuntu Core, ROS-aware distributions. Provides the platform for middleware, runtime, and robotic applications.
Robot Control denotes the role of software responsible for motion control, command execution, coordination of actuating elements and the direct operational logic of the robot.
Functional role for robotics software focused on the human-robot interaction (HRI) layer. It includes building the robot's persona (personality), a consistent style of speech, voice selection, social and emotional behaviour, dedicated knowledge bases for specific industries (e.g. reception, sales, advisory, care), and interaction-scenario management. Complementary to the roles of high-level compute (task planning) and robot learning (policy training).
The Physical AI orchestration role describes software that ties perception, AI decisions and multi-robot control into a single production workflow. The orchestration layer assigns specific tasks to specific machines, monitors the real-time state of the process, tunes execution parameters (e.g. contact force, feed rate, motion trajectory) and reports production KPIs. It typically sits above the robot control layer and below ERP/MES.
