ISAP Core Line

US-sourced, fully integrated rotary joint actuators — motor, precision gear stage, multi-sensor fusion, and on-board drive in one module. Designed to NDAA provenance requirements; sourcing verified at first production build. Select a model; the geometry is generated live by Forge-CD, our computational-design layer.

Specs are engineering targets
Pricing on production terms
ISAP-D45 and ISAP-D30 dev kits are orderable now: $9,500 per joint, invoiced after a short review.

Forge-CD parametric representation. Each drawing is generated from the model's ActuatorSpec against the ratified ISAP mounting family (ICD §3: pilot ≈ OD+12, PCD = pilot+10, flange = PCD+8, pilots snapped to stock g6 sizes) — the same spec-in → geometry-out logic behind our production part families. Front face, pilot register, bolt circle and ISO output pattern redraw per model; nothing here is hand-drawn.

You'll hear from us when this model reaches production release — and for the occasional engineering update worth your time.

Pro (active-cooled) and Space (rad-tolerant) Core variants are configured and quoted per program. ISAP Lite, a cycloidal precision line for global supply, is in development. Start a program conversation ↗

ISAP-D

Backdrivable planetary joints for humanoid and legged robots

Two joints on one platform: the same motor, housing, driver, encoders and cross-roller output bearing, with the planetary gear kit setting the SKU. Open EtherCAT with a published interface, and no locked firmware. Designed for US production. These are catalog parts with one published price for every buyer, and dev kits are orderable now.

01 · REQUEST

Send the form below: model, quantity (1–4 dev kits per model) and end use. Nothing is charged yet.

02 · REVIEW

We confirm fit and lead time and screen the order against US export lists, usually within two business days.

03 · INVOICE

You get an invoice with a confirmed ship date: 50% with order, 50% before shipment. ACH, wire or card.

Each dev kit: the joint with harness, mounting adapter, bench power supply and case, plus the interface control document, integration guide, an SDK with EtherCAT examples, and the joint's measured datasheet.

Shipping: US addresses; international orders by quote. Five or more units, production lots or custom work are quoted under our standard commercial terms (production: 50% material deposit, balance on delivery). Warranty: 90 days on dev kits, 12 months on production joints. Specs are design targets until dyno data is published.

Outside the US, or five or more units: we'll reply with a quote under our standard terms instead of an invoice.

Nothing is charged now. We review each order, then email an invoice with a confirmed ship date.
