Who this fits
For robotics teams building serious bipedal platforms where catalog samples are too weak, too long, or thermally unstable.
Custom hip, knee, and ankle actuator manufacturing support for bipedal robots where impact load, holding torque, thermal derating, braking, and output stiffness drive the design.
This page should help a robotics buyer decide whether this product family belongs in the RFQ path and what evidence must be attached before a prototype or pilot order is credible.

Peak overload: Gait and fall-event dependent
Output shaft play appears after impact or long gait cycles
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Peak overload | Gait and fall-event dependent | Leg actuators see short high-load events that can destroy reducers or bearings if sized from nominal torque only. |
| Holding behavior | Brake and current dependent | Knee and ankle joints often need predictable behavior during power loss, emergency stop, or static posture tests. |
| Output stiffness | Reducer, bearing, and housing dependent | Lower-body joints need low deflection under load to avoid control instability and mechanical wear. |
Product selection is only useful when it connects to a buyer-visible evidence path. These proof gates turn the page from a capability description into an RFQ checklist.
| Proof Gate | Evidence to Ask For |
|---|---|
| Drawing baseline | CAD package, controlled drawing revision, CTQ list, open trade-offs, NRE scope, and prototype/pilot responsibility. |
| RFQ evidence package | Buyer-side package with joint map, CAD/drawing baseline, torque-speed or force-stroke targets, validation request, pilot quantity, and report expectations. |
| Evidence library | Stage-by-stage map for CMM, FAI, actuator validation, electronics/FCT, traceability, NCR, packaging, and pilot release records. |
| Test plan checklist | Operating cycle, fixture boundary, torque-speed or force-stroke method, thermal-rise setup, backlash method, FCT, endurance, and report handoff. |
| Sample PO checklist | Drawing revision, CTQ acceptance limits, report deliverables, sample variants, buyer-supplied boundaries, change rules, packaging, and delivery records. |
| Manufacturing proof | FAI, CMM, datum checks, bearing fit, flange flatness, output runout, surface treatment, and outgoing reports. |
| Actuator validation | Torque-speed, thermal rise, backlash, noise, FCT, burn-in, traceability, nonconformance, and pilot release records. |
| BOM and sourcing control | Approved parts, restricted suppliers, substitutions, lead time, firmware boundary, harness, packaging, and second-source risk. |
A serious custom actuator inquiry should show how the selected product family moves from feasibility review into repeatable pilot manufacturing.
Review CAD, joint load, envelope, thermal boundary, cable path, and custom actuator architecture risk.
Build the first sample against defined torque-speed, fit, electrical, mechanical, and inspection assumptions.
Run thermal, backlash, noise, endurance, impact, metrology, and functional checks against the application duty cycle.
Freeze drawing/BOM revisions, evidence package, outgoing inspection, packaging, spare strategy, and repeat-build controls.
This form is prefilled with Custom Humanoid Leg Actuators. Add CAD envelope, torque-speed target, duty cycle, validation needs, quantity, and schedule so the response can start with DFM questions instead of generic sample pricing.
Yes. The design trade-offs are different, but both can be reviewed through the same joint-map and CAD-based ODM process.
Yes. A benchmark model helps frame torque, size, interface, and control expectations, but final quotation still needs your actual duty cycle and envelope.
