Selection breadth
- Typical Range
- Multiple actuator families per joint group
- Buyer Relevance
- Prototype teams need options because the final robot architecture often changes after the first tests.
A sourcing path for humanoid robot teams that need several actuator sizes quickly for prototype trials, bench testing, and first walking or manipulation experiments.
Reference visual for selection context. Confirm controlled drawings, CAD path, and test records for shortlisted models.
Engineering Asset Status
Current site images are reference selection visuals for catalog navigation. They should not be treated as final factory photos, CAD drawings, test records, or lot-specific inspection documents. For shortlisted models, request the controlled packet tied to model code, drawing revision, test condition, and sample lot.
Reference visuals, product-family routes, RFQ class matrices, and validation checklists for early selection.
Controlled datasheet, drawing or CAD path, torque-speed or thermal record, wiring notes, and sample or OQC evidence.
Verified factory-floor photos, teardown images, and lot-specific test reports are not presented as public evidence until real project assets exist.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Selection breadth | Multiple actuator families per joint group | Prototype teams need options because the final robot architecture often changes after the first tests. |
| Quote speed | Best with complete joint-map data | A clean joint map reduces clarification cycles and speeds sample purchasing. |
This map turns the solution context into concrete document requests. Use it to decide which records, interface details, and sample checks should be available before moving from shortlist to PO, sample testing, or pilot planning.
| Validation Focus | Buyer Risk | Documents to Request | Test Record | Interface Input | Go / No-Go Signal |
|---|---|---|---|---|---|
| Whole-robot joint map | The team buys scattered impressive samples that do not fit a coherent humanoid architecture. | Model summary by joint group, actuator class shortlist, accessory boundary, and available sample variants. | Early samples usually need outgoing inspection notes and basic bench bring-up records before deeper testing. | Robot mass, height, payload, joint list, rough torque-speed estimates, voltage, and control stack. | Major joint groups have a defensible first model family and backup option before PO release. |
| Fast sample bring-up | Samples arrive without compatible controller, encoder, harness, or protocol information. | Datasheet, accessory list, wiring or pinout note, controller match, brake option, and protocol note. | Bench power-up note, current-limit assumption, encoder readout check, and basic no-load operation note. | Available lab power supply, bus voltage, communication interface, software stack, and safety limits. | The buyer can run a controlled bench test without sourcing missing integration parts after delivery. |
| Prototype-to-pilot traceability | The accepted sample configuration changes before the next robot build and forces requalification. | Revision ID, firmware or driver boundary, connector and harness baseline, and sample acceptance checklist. | Outgoing inspection record type and any revision-change note tied to the shipped sample batch. | Expected sample quantity, pilot quantity, delivery sequence, and which robot build will receive the units. | Sample and pilot discussions reference the same configuration baseline and documented exceptions. |
These standard classes give buyer teams a practical starting point for samples, fixture planning, and engineering quotation scope before custom interfaces are frozen.
