The DIY humanoid companion program — for people who'd rather build the future than wait for it.
Companion robotics is arriving either way. The question is whether ordinary people get to understand it, shape it, and own what they build — or whether it stays locked inside corporate labs and seven-figure price tags. VESPER exists for the first future: a staged, honest, safety-first path from a $400 voice node on your workbench to a genuine humanoid platform.
You build it. We publish the engineering — the same staged guides, acceptance tests, and safety architecture our own team uses. We supply it. Every component is sourced from the manufacturers and distributors cited in our guides. We stand behind it. When a gate fails, our support team troubleshoots from the same documentation you hold.
Our core rule runs through everything we sell: the language model may suggest a goal, but a deterministic safety controller decides whether motion is allowed. Emergency stops, speed and force limits, and collision handling keep working even if the network fails. We publish our risk register openly because trust is engineered, not marketed.
Component prices are published estimates — verified anchor plus 15% — re-verified before you pay. Shipping at cost. Books are priced once, yours forever, with no subscription. If a part doesn't fit your stage, we tell you before you buy it, not after.
