Short answer
Contract manufacturers run many customers' products on shared lines, which gives variety, but the designs, work instructions, bills of materials and often the right to film belong to those customers. A contract manufacturer's own process footage and know-how may be licensable once customer content is excluded or approved. Expect customer-by-customer permissions, confidentiality terms and export-control questions, and scope the request around products that can be cleared.
Why they are attractive and awkward
Contract manufacturers, including electronics assemblers, machine shops, harness makers and molders, build many products for many customers. For a humanoid program that variety is the draw. Short runs, changeovers and mixed lines are exactly the conditions a general-purpose robot will meet, and one supplier relationship can span many product families and station types. Their plants also keep documentation: routings, work instructions, test records and sometimes station cameras.
The awkward part is that almost nothing on the floor is the contract manufacturer's own product. The customer owns the design, and the manufacturing agreement usually binds the plant to confidentiality, often with limits on photography. An OEM plant licensing footage of its own product decides alone; a contract manufacturer typically cannot. The OEM case is described in the manufacturing and assembly hub, and the 3PL equivalent, where goods belong to clients, in client-owned inventory rights.
Who owns what
| Asset | Typically made by | Whose content | The question to ask |
|---|---|---|---|
| Wide facility and process footage with no product detail | Contract manufacturer | Plant's, with workers on camera | Is product incidentally readable? Worker consent? |
| Station video of customer products | Contract manufacturer | Customer's design visible; plant's operators | Customer approval for this use |
| Work instructions | Plant engineers, from customer specifications | Mixed | Does the text embed customer content? |
| Drawings, bills of materials, routings | Customer or plant | Customer's | No license without the customer |
| Test and inspection records | Plant | Customer's product, plant's records | Customer data clauses |
| Time studies and standard work | Plant or consultancy | Plant's, may reveal product | Consultancy ownership; see time-and-motion study recordings |
| Generic technique training the plant made | Plant | Plant's | Easier, subject to people and third-party content |
| Tooling and fixture data | Either | Often the customer's if customer-funded | Who paid for and owns the tooling |
Ownership turns on the contract, not on who holds the file. A plant's right to hand over a recording of a customer's product is only as good as its agreement with that customer.
Layers of permission
Four layers usually stack. The plant holds rights in its own recordings and processes. Each customer holds rights in its product designs and data. The workers on camera, whether employees or agency staff, have their own interests; see worker consent and identifiable people. Third parties can hold rights in on-screen software or equipment documentation that appears in frame.
Much of the constraint here is contractual confidentiality rather than copyright, so a copyright analysis alone does not clear footage. The US Copyright Office's pre-publication report on generative AI training identifies points in development where copying may implicate rights and examines licensing options (U.S. Copyright Office, 2025). The practical lesson is to obtain express permission for each intended use rather than depend on how that debate resolves. This is not legal advice.
If you are one of the plant's customers, you may already control the design side of your own product. You would still need the plant's agreement for its process and operators, and you would need other customers' items kept out of frame.
Routes to clear footage and records
- Scope to plant-owned assets. General process footage, facility layouts, technique training the plant produced, and time studies of generic tasks, with product detail excluded or masked.
- Customer-by-customer approval. The plant asks each customer in turn. Some will agree, some will decline, and the approvals need to be tracked in a manifest.
- Commissioned recording with cleared or surrogate parts. Record on products a customer has approved, or on dummy or generic parts, so no confidential design is present. If no existing asset fits, SourceX can scope a commissioned collection of new recordings.
- Buyer as customer. Record your own product line at the plant, with the plant's consent for its process.
Approvals bias the result. The customers most willing to let footage out are often those with the least sensitive products, so a cleared set can skew toward simpler assemblies. Ask for counts by product family and process, not a single total, and see whether the sensitive categories you actually need are represented. Assembly demonstration video and process-monitoring camera footage cover what to check in the footage itself.
What contract-manufacturer data can and cannot support
Can support: variety across products, processes and volumes; high-mix and changeover behavior; process records tied to station video; coverage of several station types in one supplier relationship; evaluation sets split by customer or product family, where enough customers are cleared.
Cannot support: robot actions or contact forces, which no plant video contains; claims of generalization across customers if only one or two are cleared; any asset whose customer declined; or the customer's drawings and parts data by default.

Export-control and customer-regulation flags
Ask whether any product or technical data is subject to export-control or defense-related restrictions, or to a customer's regulatory requirements. Suppliers are US businesses and buyers can be anywhere, so a transfer abroad can matter. These restrictions can also limit who may view material during annotation. Treat them as exclusion criteria set before collection, not as clean-up afterward. This is not legal advice.
How to evaluate a contract manufacturer as a supplier
- Customer mix and clearability. How many product families can be cleared, and for which uses?
- Clip-level traceability. Can the plant say which customer's product appears in each clip?
- Contract terms. What do its manufacturing agreements say about photography, data sharing and residual knowledge?
- Masking capability. Can part markings, labels and drawings be masked before delivery?
- Workforce. Employees, agency staff or both, and who gave notice.
- Revocation. What happens if a customer withdraws approval later?
- Sites. How many sites and process types are in scope?
Questions to ask contract manufacturers
- Which customers' products appear in the footage and records on offer?
- Do your agreements with customers address photography, data sharing or use of information for AI training?
- Have any customers approved, declined or not been asked?
- Can you identify the customer for each clip and exclude clips by customer?
- Which assets are entirely yours, with no customer content?
- Do any products carry export-control or defense-related restrictions?
- Are operators employees or agency staff, and what notice or consent covered recording?
- What happens to delivered material if a customer later objects?
- Who owns the tooling, fixtures and process documents that appear in frame?
Discuss your requirements
If you are scoping a contract-manufacturing source, tell SourceX the processes, product types, assets and permitted uses you need. SourceX looks for US businesses that hold suitable material, checks the data and the supplier's licensing permissions, and coordinates the license and delivery. Nothing is contracted until a supplier agrees. A request does not guarantee a match; SourceX follows up about potential sources. Rights questions that recur across manufacturing are in manufacturing data confidentiality and confidential business information in workplace footage. The humanoid training data guide covers the wider sourcing map, and SourceX's manufacturing buyers page gives industry context.
