Home / What we source

What we source

Everything below is sourced against your spec, not held in stock. Quantities shown are the ranges we can actually get quoted, not marketing ranges. If a line falls outside this list, ask anyway.

Motion

The bulk of a humanoid or arm BOM by value, and where selection mistakes are most expensive.

  • Joint actuator modules 1–500
  • Frameless torque motors 1–500
  • Servo motors and drives 1–500
  • Harmonic reducers 1–500
  • Planetary and cycloidal gearboxes 5–500
  • Planetary roller and ball screws 1–500
  • Linear actuators and rails 1–500
  • Crossed roller bearings 10–2k

Manipulation

Where the datasheet and the bench result diverge most often. We ask for test conditions on every quote.

  • Dexterous hands 1–100
  • Two and three finger grippers 1–200
  • Six-axis force/torque sensors 1–100
  • Tactile sensors and skin 1–100
  • Tool changers 1–100

Perception

Cameras and lidar carry real export and certification questions. We check those before quoting, not after.

  • RGB-D and stereo cameras 1–500
  • Solid-state and mechanical lidar 1–200
  • IMU modules 5–2k
  • Absolute and incremental encoders 5–2k
  • ToF and proximity modules 10–5k

Compute and control

Availability moves weekly on compute. We quote against live stock and re-confirm before you pay.

  • Jetson carrier boards 1–500
  • Motor drivers, CAN / EtherCAT 1–1k
  • Robot controllers 1–200
  • Custom PCBA 10–5k
  • Wiring harnesses and connectors 10–5k

Power

Battery shipping is the single most common reason a robotics order slips. We plan the freight first.

  • Custom battery packs 1–500
  • BMS 5–1k
  • Chargers and docks 1–500
  • DC/DC converters 10–2k

Custom manufacturing

Send a STEP file and a drawing with tolerances. Without tolerances we will quote the cheapest interpretation, which is rarely what you want.

  • CNC machining 1–5k
  • Sheet metal and laser 10–5k
  • Injection moulding 500+
  • Die casting 500+
  • Carbon fibre layup 1–500
  • Anodising and surface finish 1–5k

What we will not source

A short list, but a firm one. We would rather lose the enquiry than find out later.

  • Anything under export control in either directionIncluding some lidar, thermal imaging and high-end compute. We check before quoting, not after you have paid.
  • Obvious military or weapons end useIf the application is unclear we will ask. A vague answer is a decline.
  • Copies of a competitor’s patented designSend us your own drawing, not a photograph of someone else’s product.
  • Lines where we have no verified supplierWe say so on day one rather than guessing and hoping. Expect a short refusal list on most first BOMs.
  • Orders below our minimum fee that are also complexA single catalogue part at low value is fine. A twelve-line custom BOM worth $300 is not something we can do properly.

Send us the list

Paste what you have. The intake below will sort it into categories and flag anything we need to ask about.

BOM intake |paste from Excel, CSV or a parts list |NDA on request before drawings

One part per line. Include a quantity if you have one. Rough is fine — we will come back with questions.

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.
