Component layer A · Priority 01
Joints, drives, transmissions, motors and feedback—normalized at the test-condition level.
These records test whether the same claim-level schema can preserve meaningful differences across unlike products.
A field-oriented modular actuator whose official datasheet separates continuous torque from peak torque and publishes environmental and sensing information.
A compact networked servo whose highest torque figure is explicitly a stall value at a specified voltage and current—not a continuous joint rating.
A low-ratio integrated actuator marketed for legged robots, exoskeletons and AGVs with rated and peak torque published separately.
A current MYACTUATOR V4 module whose page publishes rated, peak, speed, mass, back-drive, backlash and control-accuracy values through an embedded technical-parameter image.
A current T8+ series-elastic module with continuous and peak torque separated in the same family table.
A higher-torque H-Series module with a harmonic reducer, published continuous torque and an optional fail-locked brake.
A 24 V DYNAMIXEL-P actuator whose continuous values are published but explicitly calculated from the core-motor specification.
A compact current-controllable servo whose page explicitly warns that the headline stall torque is not a continuous rating.
A 24/48 V low-ratio actuator whose rated speed is published separately for the two supply voltages.
A larger AK-series module with dual encoders and distinct rated, peak and no-load rows in the same comparison source.
A high-speed T8+ series-elastic configuration with continuous and peak torque kept separate.
A larger T-Series configuration with 20 N·m continuous torque and a 20 mm through-bore.
A 45 N·m continuous H-Series configuration with published angular accuracy and an optional fail-locked brake.
A compact high-speed DYNAMIXEL whose voltage-specific stall and no-load endpoints are explicitly not continuous ratings.
An IP68 DYNAMIXEL with high reduction and voltage-specific stall torque, kept outside continuous-torque comparisons.
A high-ratio AK actuator with 48 N·m rated torque and a published manufacturer backlash figure.
A hollow-shaft 6:1 module with a separately published radial-load figure for routing through the joint.
The exact TurtleBot3 Burger actuator identity with voltage-conditioned stall and no-load-speed claims. The official manual explicitly warns that stall torque is not continuous output or real-world performance.
The exact six-unit DYNAMIXEL LeKiwi leader-arm actuator identity. Its official e-Manual publishes voltage-conditioned stall torque and no-load speed while leaving continuous thermal output and robot-level validation unknown.
The exact four-unit DYNAMIXEL LeKiwi follower-arm actuator identity. Its higher reduction changes the voltage-conditioned stall and no-load endpoints without supplying a continuous thermal rating.
An exact size-and-ratio gear-unit record. Published torque and stiffness values remain rating-table claims, not an RCI robot-joint duty-cycle, thermal, life or backlash test.
The order number, enclosure and control-input variant are retained. The record describes a compact integrated drive, not a complete robot joint with gearing, bearing, feedback, brake or independent thermal validation.
The RV-20E size and ratio-57 row are kept together so ratings from another ratio or RV product form cannot silently migrate into this record. It remains a customer-integrated reducer component, not a complete robot joint or actuator.
The full catalog example configuration freezes frame, stack, winding, thermal-device, sensor, connection, field and custom fields. Published torque is retained with winding-temperature rise, ambient, housing, heatsink and sinusoidal-commutation conditions.
This record freezes the TTL “T” communication suffix used by the TurtleBot3 Waffle Pi BOM. The official page combines T/R mechanical performance, so RCI carries only the explicitly suffix-specific TTL interface into this exact T record and keeps stall torque separate from continuous output.
The joint module Unitree uses twelve of in the Go1 quadruped, sold as a standalone actuator. The official page publishes maximum torque and speed as endpoints tied to the 6.33 reduction ratio and a 24°C measurement note; no continuous or thermally rated torque envelope is published.
This record freezes the third beta revision of the mjbots quasi-direct-drive servo. The official page is unusually explicit about torque-versus-time behaviour, publishing a four-step torque-duration ladder down to an indefinite 3.3 N·m point under one stated thermal condition. The page also states the unit is not currently stocked and carries a 50-unit minimum order.
This record freezes the CAN-bus, no-brake product code RMD-X8-P9-25-C-N. The official details page states the previous name of this actuator was RMD-X8 Pro 1:9 and today lists it under the V2 single-encoder generation, not V3; the RS-485 code RMD-X8-P9-25-R-N shares the same parameter table. Unusually for this vendor, the parameter image defines the rated-torque test method as a thermal-balance long-term working point.
This record freezes the 7.4 V-class variant ST-3215-C001 of the STS3215 family and preserves the official page’s voltage wording exactly: the title and description market the servo as “7.4V 19KG”, while the specification table states an operating voltage range of 6-7.4V and attaches its only stall-torque figure, 19.5kg.cm, to 6V. RCI does not resolve this internal tension (documented voltage-conflict note RCI 049). The 12 V variant ST-3215-C018 is a separate record.
This record freezes the 12 V-class variant ST-3215-C018 of the STS3215 family as a separate record from the 7.4 V-class ST-3215-C001, demonstrating the variant-split rule. The official page markets the servo as “12V 30KG” while its specification table states an operating voltage range of 4-14V; RCI preserves both statements without resolving them.
This record freezes the 24 V column of the official V1.2 user manual; the manual publishes 24 V and 48 V variants side by side and RCI carries 48 V-only values solely as variant notes. The current hardware revision on the official dmBots repository is V1.2 (the V1.0 manual is filed with a discontinued marker), so the informal “DM4310 V4” designation is not used. There is no “V4” revision on the official surface.
An exact size-and-ratio gear-unit record frozen from the official exact-model page. Rated, average, repeated-peak and momentary-peak torques are four separately conditioned catalog values and are transcribed separately; none of them is an RCI robot-joint duty-cycle, thermal or life result.
An exact size-and-ratio gear-unit record for the high-torque CSG unit family, frozen from the official exact-model page. All torque figures remain separately conditioned rating-table claims, not RCI robot-joint measurements.
The RV-25N size and the ratio-81 selection column are kept together so ratings from another ratio or RV product form cannot silently migrate into this record. Rated torque is defined at the published rated output speed; the acceleration/deceleration and momentary maxima are separate allowable values with their own conditions.
The official LCS page publishes a series-size-ratio parameter grid without one orderable purchase code, so this record freezes the grid coordinates size 20, ratio 100. All values are Leaderdrive catalog-table claims; substitution for or interchangeability with any other manufacturer’s strain-wave product is not established by this record.
The official FSS page publishes a series-size-ratio specification grid with per-build weights but no single orderable purchase code, so this record freezes the grid coordinates size 20, ratio 100. Rated torque is explicitly defined at 2,000 r/min input. Substitution for or interchangeability with any other manufacturer’s strain-wave product is not established by this record.
This record freezes the 50 mm frame, 12.7 mm stack, A-winding TBM2G size with the standard NNAA-00 option string (no thermal device, no Halls, 0.5 m leads, standard field, custom code 00), clearly separated from the already-cataloged TBM2G-07608 size. Published torque values carry their winding-temperature-rise, ambient, housing, heatsink and sinusoidal-commutation conditions.
This record freezes the 85 mm diameter, 13-class stack size of the ILM-E series in the star-serial interconnection published in the official data sheet. Rated torque carries the manufacturer condition that thermal behavior depends strongly on the installation situation, and peak torque carries its 20%-deviation-from-linearity definition.
This record freezes maxon ordering number 734439 from the current EC frameless DT range; the older EC frameless flat parts (for example 548273 and 588849) are marked NRND in the same catalog and are deliberately not selected. Values are the catalog figures at 48 V nominal voltage; stall figures are electrical endpoints, not thermal ratings.
This record freezes the 24 V winding of the Series 3268 … BX4 (62 W, 96 mNm series headline). Datasheet values are at 22 °C and nominal voltage; the continuous ratings are the manufacturer-calculated rated values with the Rth2 thermal resistance reduced by 25%, and stall torque is kept separate from the continuous rating.
This record covers the ODrive Pro servo drive with drive-specific fields: DC bus voltage range, cooling-conditioned continuous and peak phase-current ratings, and published interface and encoder-support lists. The official datasheet and the official shop page publish different voltage and continuous-current boundaries; both are recorded and the conflict is left unresolved.
This record freezes the 25 A / 100 V rating point of the Gold Twitter family from the official product page, which publishes numeric model-level tables without a form gate. Continuous current is carried in both amplitude and RMS forms as published, and the peak rating is recorded exactly as the published 2 × Ic multiple because no duration is stated on the cited page.
First deliverable
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.
