Your practical starting point
Turn the hardware-founder post into action. Follow the steps, use the linked tools, and buy equipment only when you reach the right checkpoint.
Suggested milestones, not a guaranteed launch schedule. Tick boxes as you work; progress lasts for this page session.
You do not need everything here. Start with the recommended tools in your current step. Paid alternatives and later-stage services are clearly marked.
Links go to official product pages, documentation or vendor storefronts. Check the local currency, shipping, tax, stock and kit contents before purchasing. Budget figures below are planning estimates, not live offers. No affiliate links.
Set a maximum spend for the next piece of evidence. These allowances exclude your time, existing computer, shipping and tax; replace them with quotes for your design and country.
| Milestone | Planning allowance | Release the money when… |
|---|---|---|
| Problem researchAny path | $0 | You can start now with interviews and public reviews. |
| Simple prototypeOutsourced plastic print + basic measuring tools | $50–$200 | A few target users confirm the problem and agree to try a solution. Tiny prints can cost less; large parts and repeated revisions cost more. |
| Connected prototypeAdditional electronics, beyond the enclosure | +$50–$250 | You know the sensor, power and connectivity requirements. Start with development boards and modules. |
| Your own printerOptional equipment | Get a local quote | Repeated print orders or turnaround delays justify ownership. Include filament, failures, space and maintenance. |
| Robot experimentLearning/pilot hardware; not a deployable business | $500–$3,000+ | The task fits the chosen kit. This illustrative range may cover a small arm setup, cameras and parts; compute, integration and field deployment can cost much more. A quadruped or industrial system needs its own quote. |
| Small production batchSamples first, then perhaps 10–25 units | Quote from your BOM | Paid pilots, quality checks and margins support the order. There is no useful universal “first 100 units” price. |
Buying from Canada? These estimates are USD, not CAD. Use the Canadian storefront where available and account for exchange rates, shipping, duties and GST/HST.
Use video to understand the task. Standard π0/openpi fine-tuning needs compatible robot observations and action demonstrations, data preparation, compute and evaluation. LeRobot helps with these workflows; simulation-to-real transfer still needs validation.
Confirm the exact Unitree model, SDK access, control interfaces and permitted use in writing. Hugging Face’s $399 announcement described Reachy Mini Lite, a desktop robot, not a biped. That announcement price is not a current quote. Choose a robot for reach, payload and task compatibility.
Compare materials, tolerances, process capability and samples. The third-cheapest supplier has no special advantage. A $50 sample is not universal, and 1688 domestic listings are not equivalent to delivered export quotes.
Include assembly, shipping, fees, defects, returns and support. Reviews suggest demand; they do not prove your economics. “5× COGS” is a hypothesis to test against customer value and your full cost to deliver.
