Observe how it moves.
Use vision to inspect posture, gait symmetry, alignment and visible assembly abnormalities.

ROBOT DIAGNOSTICS
Know your robot before it fails.
Robodiag actively exercises robots, captures internal telemetry and external signals, and turns anomalies into evidence-backed diagnosis from the factory line to field service.

Core Method
Command → Observe → Compare → Diagnose.
Robodiag goes beyond passive fault-code reading. It actively excites the robot, observes the response, compares it against healthy baselines, and produces an evidence-backed diagnosis.
01 / COMMAND
Active Excitation
Run standardized movements and test sequences designed to expose latent faults.
stand → squat → walk → joint sweep
02 / OBSERVE
Multimodal Sensing
Capture internal telemetry together with external vision, acoustics and vibration.

03 / COMPARE
Health Baseline
Compare a robot with golden units, fleet norms and its own historical behavior.

04 / DIAGNOSE
Evidence, Not Guesswork
Turn signal deviations into PASS / FAIL, fault localization and probable causes.

Diagnostic Evidence
望 · 闻 · 问 · 切
The Observe step is more than reading one sensor. Robodiag collects four kinds of evidence: visual behavior, sound, internal telemetry and physical response.
FROM OUTSIDE TO INSIDE
闻
LISTEN
Hear what motion reveals.
Acoustic and vibration signatures can expose friction, impact and abnormal mechanical behavior.
ACOUSTIC · VIBRATION · NVH
问
ASK
Read what the robot reports.
Read joint telemetry, temperatures, currents, logs, fault memory and test history from inside the robot.
TORQUE · CURRENT · TEMP · LOGS
切
PROBE
Measure its physical response.
Measure force, torque, contact and vibration while the robot runs controlled tests.
FORCE · TORQUE · CONTACT · VIBRATION
The name comes from 望闻问切 — the four diagnostic methods of traditional Chinese medicine, set out in classical Chinese texts more than two thousand years ago: observe the patient, listen to the breath, ask about the symptoms, feel the pulse. Robodiag keeps the same outside-in order — watch how the robot moves, listen to how it sounds, ask what it reports, then measure how it responds.
Why Robodiag
Robots are getting smarter.
Testing is still fragmented.
As robots move from prototypes to products, testing must become repeatable, measurable and traceable.

Use Cases
From manufacturing EOL to field service.
Manufacturing EOL
Every robot leaves the line with a standardized, traceable health record.
Incoming / Outgoing Quality
Verify modules, assemblies and finished robots using consistent test procedures.
Service & Maintenance
Diagnose robots before replacing parts and reduce unnecessary service effort.
Our Vision
The diagnostic infrastructure for every robot.
As robots scale from prototypes into products, diagnosis becomes infrastructure. Robodiag is building the test and health layer that makes robots manufacturable, serviceable and trustworthy.
