AUDITED RECORDS

Current pressure-test sample.

These records test whether the same claim-level schema can preserve meaningful differences across unlike products.

Integrated rotary joint actuatoractive

HEBI Robotics

R8-9+

A field-oriented modular actuator whose official datasheet separates continuous torque from peak torque and publishes environmental and sensing information.

6 claims6 MChecked 2026-08-09
Networked smart servo actuatoractive

ROBOTIS

XH540-W270-R

A compact networked servo whose highest torque figure is explicitly a stall value at a specified voltage and current—not a continuous joint rating.

CubeMars

AK80-9 V3.0 KV100

A low-ratio integrated actuator marketed for legged robots, exoskeletons and AGVs with rated and peak torque published separately.

First deliverable

Expand the integrated-joint file to 25–50 audited models with stronger thermal evidence

Publication gate: a record needs a stable model identity, at least one traceable first-party source, useful integration fields, a last-verified date and visible evidence labels.
