Integrated joint modules, frameless torque motors, servo drives.
Paste your BOM. Three quoted Chinese suppliers in 48 hours.
We source actuators, reducers, sensors, hands, batteries and custom machined parts for robotics teams building 1 to 500 units. Every line is reviewed by someone who has audited the factory, not matched by a search index.
One part per line. Include a quantity if you have one. Rough is fine — we will come back with questions.
| Line | Category | Qty |

We reply from a named person, not a ticket queue. If we cannot source a line, we say so on day one instead of going quiet.
What we source
Sourced against your spec, not held in stock. If a line falls outside this list, ask anyway — most of what we decline is a scope call rather than a capability one.
Harmonic, planetary and cycloidal drives. Roller and ball screws.
Force/torque, tactile, encoders, RGB-D cameras, lidar, IMU.
Dexterous hands, two and three finger grippers, tool changers.
Custom packs, BMS, chargers, DC/DC. Freight planned up front.
CNC, sheet metal, moulding, carbon fibre, anodising.
How it works
Four steps, with the timing we hold ourselves to. If we are going to miss one, you hear it before the deadline rather than after.
You send a BOM or a spec day 0
A parts list, a spreadsheet, a STEP file, or a paragraph describing the robot. We come back within one business day with the questions we need answered to quote accurately.
We quote three suppliers per line 48 h
Three where the market supports it, fewer where it genuinely does not, and we tell you which case you are in. Each quote lists unit price, MOQ, sample lead time, production lead time, and the test conditions behind the headline spec.
Samples first, always 1–3 wks
We do not let a first order go straight to production quantity, even when you want to. Samples ship to you directly with the supplier’s test report and our own incoming check on dimensions and basic function.
Production, inspection, freight 4–10 wks
We book the factory slot, inspect before shipment against the criteria you set at sample stage, handle export documents including battery and lidar paperwork, and stay the point of contact until it clears customs.
What we take on, and what stays with you
Most sourcing agents are vague here and it ends badly for both sides when a part fails on your bench. Ours is written down before you send a purchase order, and repeated in every quote.
We are responsible for
- Supplier verificationBusiness licence, export history, and a visit to the floor before we quote a new factory.
- Spec conformanceThat the part delivered matches the datasheet the supplier quoted, including the test conditions behind peak versus continuous figures.
- Incoming inspectionDimensional and functional checks against criteria you agree at sample stage, with photos and measurements before shipment.
- Commercial and freightNegotiation, contracts, export documentation, dangerous goods paperwork for cells, and customs clearance to your door.
- Rework and replacementIf a part is out of spec, we take it up with the factory and cover the return leg. That is our fight, not yours.
You are responsible for
- Selection and fitness for purposeWe will tell you what a part can do and flag when a spec looks wrong for your load case. Deciding it suits your robot is your engineering call.
- Duty cycle and thermal designAn actuator run past its continuous rating will fail. That is a design outcome, not a defect, and it is the most common dispute in this trade.
- Certification for your marketWe supply the supplier’s CE, RoHS or UN38.3 documents. Certifying your finished robot is on you.
- Design IPYour drawings stay yours. We sign an NDA before receiving them and pass a back-to-back one to the factory.
Why not just go direct
Often you should. If you are ordering a catalogue part in volume from a supplier you already trust, buy it direct and keep the margin. This is what changes when you do not have that.
| Open marketplace | General trading agent | Datum | |
|---|---|---|---|
| Who answers you | Sales staff working from a template | A generalist who also sells lighting and textiles | Someone who has held the part and read the test report |
| Spec verification | Whatever is typed in the listing | Passed through unchecked | Peak and continuous separated, test conditions requested in writing |
| Small quantities | MOQ often blocks you | Order too small to be interesting | Built for 1 to 500 units, which is where robotics teams actually live |
| Margin | Hidden in the price | Hidden in the price | Stated as a fee, with the supplier invoice shown to you |
| When a part fails | Dispute process, then silence | Blames the factory | Scope agreed in advance, so the argument is short |
Sourcing guides
Written for engineers doing this for the first time. No gated downloads and no contact form in the middle.
Peak vs continuous torque on Chinese datasheets
Why the headline number on a joint actuator spec sheet is usually the one you cannot design around, and the four questions that get you the real figure.
Shipping lithium packs out of China
UN38.3, watt-hour thresholds, air versus sea, and why battery freight should be planned before you pick a cell.
What a factory audit should actually cover
The checklist we run before quoting a new supplier, and the three things a showroom visit will never tell you.
Send one line and see what comes back.
You do not need a finished BOM to start. Send the single part that is currently blocking you and we will quote it. It costs you an email and tells you more about us than this page can.
