Best buyer fit
For teams whose robot design cannot be changed around a catalog actuator and must instead customize the actuator around the robot.
ODM pathway for humanoid actuator modules that must fit unusual robot shells, hollow shafts, ultra-short axial stacks, special cable exits, or asymmetric mounting interfaces.

Use this page when the buyer is choosing a development route for a funded humanoid robot program, not browsing a standard actuator catalog.
For teams whose robot design cannot be changed around a catalog actuator and must instead customize the actuator around the robot.
Packaging constraint severity: Low, medium, high, impossible without architecture change
A custom actuator becomes impossible to assemble or inspect
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Packaging constraint severity | Low, medium, high, impossible without architecture change | Some envelope problems require actuator customization; others require robot architecture changes before manufacturing. |
| Assembly access | Open, fixture-dependent, service-limited, or blocked | A tight actuator envelope is only useful if bearings, fasteners, harnesses, and inspection features remain reachable. |
| Thermal compromise | Acceptable, derated, heat-sink dependent, or redesign | Short stacks and sealed robot shells often reduce the heat path that high-torque actuators need. |
Send enough evidence to let engineering qualify feasibility, quotation scope, prototype validation, and pilot readiness in the same review loop.
| Evidence | What to Send | Related Path |
|---|---|---|
| Joint and program baseline | Robot phase, joint map, prototype deadline, pilot date, quantity range, and responsible engineering contact. | RFQ intake |
| Architecture constraints | Motor, reducer, encoder, driver, brake, voltage, control, bearing, housing, cable, and interface constraints. | Product families |
| Load and thermal assumptions | Torque-speed targets, duty cycle, peak load duration, ambient limit, heat path, impact load, and known failure risks. | FEA and thermal review |
| Validation and inspection plan | Torque-speed, backlash, noise, thermal, electrical, dimensional, incoming, in-process, and outgoing inspection needs. | Quality validation |
| Prototype-to-pilot release data | Approved sample reference, drawing revision, BOM revision, test records, CTQ list, pilot quantity, and forecast. | Pilot control |
A solution path should shorten the distance from buyer intent to qualified hardware, while keeping prototype evidence useful for the next build stage.
Confirm the buyer problem, robot phase, custom constraint, and whether this solution path is the right starting point.
Connect the scenario to motor, reducer, encoder, brake, driver, housing, bearing, thermal, and cable decisions.
Define acceptance tests before prototype release so sample feedback can be reused during pilot planning.
Freeze drawings, BOM, CTQ dimensions, inspection gates, packing requirements, and repeat delivery expectations.
This form is prefilled with Nonstandard Robot Envelopes. Include CAD, joint map, torque-speed target, duty cycle, envelope limits, prototype quantity, pilot schedule, and acceptance tests.


We can review the trade-off, but short axial stacks usually affect bearing support, heat flow, connector space, and serviceability.
If bearing support, heat path, inspection access, or connector space becomes unsafe, changing the robot envelope is usually cheaper than forcing the actuator.
Send the full assembly, section views, forbidden zones, cable exits, connector keep-out areas, and the robot-side load path.
