Lumi (Lightberry)

Lumi is an interactive humanoid robot developed by Lightberry for conversations, visitor guidance, entertainment and other interactions with people. It uses a Unitree G1 mechanical foundation with Lightberry's sensing hardware, computer and software. Lightberry advertises customization through spoken instructions and a software development kit.^[1][2]

Hardware

Lightberry's hardware documentation describes Lumi as approximately 1.3 m tall, with 34 degrees of freedom. The joints include three degrees of freedom in the head, three in the torso, seven in each arm and six in each leg, plus one in each parallel-gripper hand.^[2]

These figures describe Lightberry's published Lumi configuration, rather than every Unitree G1 variant.^[2]

Software and extensions

Lumi divides its software between the robot and a cloud-based AI agent. The onboard software performs perception, navigation and actions. The cloud agent handles communication understanding and high-level planning. The documentation therefore does not describe a wholly offline planning system.^[3]

The onboard operating system is a custom Linux build based on NVIDIA Jetson Linux 39.2. Lightberry recommends containers for user extensions, although extensions can also run directly in its operating system.^[3]

Extensions execute on Lumi's computer and communicate with the host software through shared memory. They can subscribe to data streams, offer callable tools and supply information to the planning agent. The SDK provides Python and Rust interfaces; other languages can bind to the Rust SDK or use iceoryx2 directly.^[4]

The documentation includes a coffee-dispenser extension that controls a pump over a serial connection, exposes a dispensing tool and reports the reservoir level to the planner. This is an integration example, rather than evidence that a coffee dispenser is standard hardware.^[4]

Availability and regulatory status

On November 4, 2026, Lightberry listed reservations at US$39,990. Its October 30 announcement identified this price with the Founder Edition and stated a 2026 shipping plan.^[1][5]

That announcement reported a conditional exemption from the FCC Covered List following a U.S. Department of War review. Lightberry linked the decision to its control over Lumi's sensors, computer and software, a plan to manufacture parts in the United States, and continued vetting. Its manufacturing plan begins with the body, head and hands; the announcement does not establish that all components are already manufactured domestically.^[5]

In a November 2 interview with Humanoids Daily, CEO Ali Attar said the exemption allowed the company to apply for independent FCC certification before off-the-shelf customer sales. The reported Covered List exemption is therefore distinct from completed equipment authorization. That interview did not establish a granted certification or a firm shipment date.^[6]
