Case Study
SCARA_01
A real-world example of how vocabulary gaps cause AI to misclassify mechanical assemblies.
What AI Said
"Industrial Manipulator"
WRONG
What It Actually Is
"SCARA Robot — 4-DOF Selective Compliance Arm"
CORRECT
Why AI Failed
Vocabulary Gap
AI used generic terms instead of precise mechanical classification. The system lacked 'SCARA' and 'selective compliance' in its lexicon, falling back to broad 'manipulator' labels.
How We Caught It
Joint Pattern Missing → Structure Similarity → Vocabulary Gap → False Negative
Our reasoning chain traced the failure from missing revolute-prismatic joint signatures through structural similarity analysis to the root vocabulary gap.
The Fix
Add Rotary-Prismatic Signature
RESOLVED
