lumi
Details
Lumi is an AI powered guidance system for manual high-mix-low-volume type assembly workstations. Using camera + projector Lumi units mounted on the workstation, the system observes the assembly process and projects contextual instructions directly onto the work surface. Operators can also interact with the system through Lumi Link, allowing them to ask questions or show areas the system cannot see.

background
Cause
Automation continues to grow in manufacturing, yet most high-mix-low-volue type assembly processes remain manual. Operators rely on memory, training or external documentation and instruction to complete complex and ever changing tasks.
When new taskes emarges, guidance is often separated from the physical workspace, forcing operators to shift attention away from their work. At the same time, valuable knowledge from experienced operators is rarely captured or shared.
Change
Lumi introduces a knowledge driven assistance system that learns from experienced operators and translates this knowledge into guidance for others.
By observing tools, parts and operator actions, the system understands the assembly process and provides visual cues directly on the work surface. Operators can also interact with Lumi through natural dialogue, allowing them to ask questions and receive assistance without interrupting their workflow.
the system
The Lumi system is designed to integrate directly into existing factory workstations. Modules attach to standard 40×40 T slot aluminium frames already widely used in assembly environments. Once mounted, Lumi can move freely along the workstation to position itself where guidance is needed.
Each unit combines cameras, sensors and a compact projector to observe the workspace
and project contextual information.
product architecture
Lumi is designed as a compact handheld module that mounts onto integrated T slot workstation frames. The attachment cage mechanism allows the device to clamp securely onto the extrusion and move smoothly along the rail. Lumi is then inserted onto the attachment cage and locks the eniter product into place, creating a stable yet flexible positioning system. This modular approach allows the system to be deployed on individual workstations, moved when needed and expanded over time.

Interaction
Interaction with Lumi happens naturally within the workspace. Operators receive guidance through projected visuals such as highlights, arrows and step indicators. Cameras and sensors observe tools and objects, allowing the system to understand the current assembly step. Voice interaction enables operators to ask questions and receive assistance without leaving their task.

The potential
Lumi demonstrates how collaborative automation can support human work rather than replace it. By capturing expert knowledge and delivering guidance directly within the workspace, the system reduces training time, prevents mistakes and helps operators on any skill level to improve their work and build confidence on the assembly line through a sort of collective knowlage base.
Over time, Lumi becomes a growing knowledge system that continuously improves how assembly
work is performed.
