There is no honest universal idea-to-production duration for an AI desktop robot. At Tecpan, a $500 public-mold custom sample is delivered in 4 weeks, and a working prototype for a fully new product takes 4 weeks after requirements are fully confirmed. Those milestones do not mean mass production is complete in 4 weeks. Industry guidance commonly breaks later work into engineering, design and production validation, with tooling, testing and iteration adding their own schedules.
| Key facts: milestone versus total program | ||
|---|---|---|
| Milestone | What it proves | Timing |
| Tecpan custom sample | One personalized public-mold desktop AI robot | 4 weeks |
| Tecpan working prototype for new product | Agreed working functionality after requirements freeze | 4 weeks after full confirmation |
| Tooling and mass production at Tecpan | Production-intent parts and repeatable output | [X weeks — to be confirmed per project] |
| Industry validation | Engineering, design and production readiness | Scope-dependent; see cited general guidance |
Why is “four weeks” not a complete production timeline?
A working prototype demonstrates agreed functions. A production program must also show that the design can be repeated with consistent parts, assembly, testing, packaging and quality. Those are different claims.
When comparing suppliers, ask what exactly will be delivered at the promised date: an appearance model, a functional engineering unit, a personalized existing product, a production-intent prototype, or finished sellable inventory. Also ask when the clock starts and which decisions pause it. At Tecpan, the new-product prototype clock starts only after requirements are fully confirmed.
What happens before the prototype clock starts?
Discovery turns an idea into a buildable brief. Define the user, core interaction, must-have functions, target cost, expected quantity and intended market. Gather sketches, references, CAD or an existing prototype if available. For a public-mold sample, confirm the name, voice, personality, language and packaging direction.
This is also the time for an NDA. Tecpan signs one before details are shared. A rushed brief may appear to save days but create a much longer correction loop later. Keep one approved requirements document and identify who can authorize changes.
What should happen during the first working-prototype stage?
Engineering selects the architecture and resolves the highest-risk assumptions: mechanical fit, electronics, power, voice or vision modules, wiring and the intended AI behavior. Design-for-manufacturing review should begin here rather than after the design is considered finished.
Prototype parts may be printed, machined or based on existing components, depending on what the team needs to learn. Assembly and testing then expose integration issues. The output should be something you can evaluate against written acceptance criteria—not simply something that turns on.
What are EVT, DVT and PVT in a hardware schedule?
Formlabs’ product-development overview describes EVT as engineering validation of the functional design, DVT as design validation as the product becomes industrialized, and PVT as validation of the production line, fixtures, yield and readiness. These stages are useful language, but their exact builds and exit criteria must be adapted to the product.
EVT asks whether the engineering works. DVT asks whether the near-final, production-intent design meets functional and reliability requirements. PVT asks whether the intended people, tooling, materials and process can build it repeatedly. Passing one gate does not eliminate the need for the next.
How long does production take after a working prototype?
Published planning guides vary because products vary. OPD Design gives a general estimate of roughly four to nine months from a mature functional prototype to initial mass production for typical custom hardware, while emphasizing that connected, regulated or mechanically complex products can take longer. Formlabs publishes a broader stage-based framework rather than a promise for a specific robot. Treat these as industry-general planning references, not Tecpan delivery commitments.
For Tecpan tooling and mass-production timing, the truthful answer today is [X weeks, to be confirmed after discovery]. We will not replace that placeholder with a generic internet estimate.
Which work can run in parallel—and which should not?
Packaging research, supplier selection, compliance planning and production-fixture planning can often begin while engineering matures. Long-lead components may need early attention. But cutting a production mold before enclosure interfaces are stable can turn a time-saving decision into expensive rework.
Parallel work should reduce waiting, not bypass validation. A visible dependency map helps: requirements before design freeze, stable interfaces before tooling release, approved parts before final assembly, and passed inspections before shipment.
What most often delays a first robot?
- Changing must-have features after the team has started building.
- Discovering that a selected component has a long lead time or unsuitable order minimum.
- Mechanical interference, thermal problems or unreliable voice/vision performance.
- Late tooling corrections or a design that is difficult to assemble.
- Market-specific compliance questions raised after the design is fixed.
- Slow feedback spread across several founders or stakeholders.
- Freight and import planning left until the unit is ready.
A schedule with review points and contingency is more credible than one long uninterrupted bar.
How can a small team keep the schedule under control?
Freeze the smallest useful scope, nominate one decision-maker, respond to questions with complete answers, and test the risky function first. Ask for a stage-gate plan that lists deliverables, dependencies and acceptance criteria. Keep shipping separate from production completion so “ready” has a precise meaning.
One coordinated team also reduces handoffs. Tecpan coordinates molds, injection molding, CNC, hardware and electronics within its Zhejiang family supply chain. See our six-stage process and the Tecpan prototype case study.
How should you plan sample shipping and launch after approval?
Production completion, inspection release, physical departure and delivery are separate dates. Add export packing, carrier booking, customs processing and last-mile delivery to the plan. The appropriate transport depends on quantity, urgency, destination and product constraints; confirm them per shipment.
Tecpan’s parent company brings 20 years of international trade experience to export coordination. Our supported shipping terms and exact transit times remain [to be confirmed], so neither should be inferred from a general factory schedule. Keep the launch plan flexible until inspection and logistics are confirmed.
What should a project timeline document show?
Use a week-by-week plan with named deliverables, owners and approval dates. Include requirements freeze, design reviews, prototype fabrication, assembly, functional tests, user feedback, tooling decisions, validation builds, inspection and shipping as applicable. Mark which dates are confirmed and which depend on an external supplier or test.
Add a change-control rule: when a requirement changes, the team records the reason and reviews cost and timing before work continues. This makes the schedule a management tool rather than a hopeful launch date.
How should you budget contingency without using a made-up percentage?
List the specific unresolved risks instead of copying a generic allowance. Examples include a second enclosure revision, replacement prototype parts, a repeated test, component substitutions or a slower approval round. Price or schedule each risk as information becomes available.
Review the list at every stage gate. When a risk disappears, remove it; when testing reveals a new one, record it explicitly. This keeps contingency connected to real project uncertainty.

Frequently asked questions
Can Tecpan deliver a production-ready new robot in 4 weeks?
No such claim is made. Tecpan’s 4-week milestone is a working prototype after full requirements confirmation; tooling and production timing are [to be confirmed].
How long does Tecpan’s $500 sample take?
The one-unit public-mold custom sample is delivered in 4 weeks. Destination shipping time and cost are extra and [to be confirmed].
Do EVT, DVT and PVT apply to every robot?
They are common hardware validation stages, but the exact builds and tests depend on the product and program. A simple existing-product customization may not need the same path as new hardware.
When does Tecpan’s prototype timeline begin?
For fully new development, it begins after requirements are fully confirmed. Changes afterward may require schedule review.
Can production preparation begin during prototyping?
Yes, suitable supplier, compliance, packaging and fixture planning can overlap. Irreversible tooling decisions should wait until the relevant design interfaces are stable.
