Reality check

The useful boundary is what works repeatedly in a real environment—not what looks impressive in a demo.

Works well when

Stable, repetitive handling, tending, welding or assembly
Processes with known parts, fixtures and cycle times
Cells where an integrator can own commissioning

Verify before buying

Payload after adding the gripper and cables
End effector, vision and safety-cell cost
Changeover time when the part or fixture changes

Not a magic solution

A solution for a process that changes every day
A turnkey cell without integration and safety work
A reason to skip measuring the current process
