Public manufacturer specifications for HEBI, ROBOTIS, CubeMars and MYACTUATOR modules with different torque definitions and interfaces.
Comparison 01 · Audit sample
Integrated joint actuator evidence table
A condition-preserving comparison of four networked actuator architectures.
Peak, stall and rated torque are different claims. Missing continuous torque is shown as unknown instead of inferred.
| Field | HEBI Robotics R8-9+ | ROBOTIS XH540-W270-R | CubeMars AK80-9 V3.0 KV100 | MYACTUATOR RMD-X8-P9-32-R |
|---|---|---|---|---|
| Continuous / rated torqueThe manufacturer’s exact label and missing thermal conditions remain visible. | 10 N·mMDatasheet headline rating; speed–torque envelope still governs simultaneous torque and speed.Source ↗ | UnknownNo adequate published value in the selected source set. | 9 N·mMManufacturer calls this rated torque; thermal duty conditions are not stated in the product comparison table.Source ↗ | UnknownNo adequate published value in the selected source set. |
| Peak or stall torqueNot a continuous operating point; read the condition. | 23 N·mMPeak rating; duration is not stated in the headline table.Source ↗ | 9.9 N·mMAt 12.0 V and 4.9 A; the e-Manual warns that stall torque is not a continuous output rating.Source ↗ | 22 N·mMPeak current 28 A; duration not stated in the visible specification table.Source ↗ | 32 N·mMThe manufacturer’s naming guide defines the final number as peak torque; this is not a continuous rating.Source ↗ |
| Speed claimMaximum, no-load and rated speed are not equivalent. | 39 rpmMMaximum headline speed; not simultaneously available with peak torque.Source ↗ | 39 rpmMAt 12.0 V; no load.Source ↗ | 390 rpmMAt the published rated operating point.Source ↗ | UnknownNo adequate published value in the selected source set. |
| MassAccessory, cable and mounting mass may be excluded. | 685 gMNo extra condition in selected source.Source ↗ | 165 gMNo extra condition in selected source.Source ↗ | 490 gMNo extra condition in selected source.Source ↗ | UnknownNo adequate published value in the selected source set. |
| Reduction ratioUnknown when absent from the cited summary source. | UnknownNo adequate published value in the selected source set. | 272.5:1MNo extra condition in selected source.Source ↗ | 9:1MNo extra condition in selected source.Source ↗ | 9:1MP9 in the current model name.Source ↗ |
| CommunicationProtocol and physical medium both affect integration. | 2 × 100 Mbps plastic optical fiberMOptoLock interface.Source ↗ | RS-485 multidropMR suffix; T variant uses TTL.Source ↗ | CAN + serial setup portMXT30 2+2 combines power and CAN; CJT 3-pin is used for setup communication.Source ↗ | RS-485MR suffix on the cited current product configuration.Source ↗ |
Values are transcribed from the linked sources and were checked on the date shown by each record. V = independently verified; M = manufacturer claimed; D = RCI derived; C = conflicting; U = unknown.
Interpretation rule
The condition belongs to the number.
RCI does not compute winners from this audit sample. The table’s purpose is to show what can be compared now, what requires a shared test, and which public fields are still missing.
