How long does it take to build a first working prototype?

On Anvol's builds, development of a first working prototype took 3 to 15 days for simple devices, 10 to 30 days for small robots, and one to two months for large robots and underwater vehicles. The delivered batch of 10 lidar cars took about one month. Shipping comes on top.

From our project sheets. Development time, not a promise for your build: your written scope gives the date.

What adds time

Before work starts
The written scope comes once the open questions are answered, so the faster those answers come, the sooner the build starts. We reply within 12 hours.
Scope changes
A major change is re-quoted, with a new date, before work continues.
Revisions
Changes found on the first prototype are made with you before you confirm it, and each one adds days.
Shipping
Not in these times. Usually arranged by you once the units leave the factory.
Certification
FCC or CE testing is done by a test lab, on its own schedule, and quoted separately.

What makes it faster

  1. Reusing proven firmware or a development board. The logic analyzer took 3 days because its firmware was reused open source.
  2. A short brief that says what the first unit must do and what it can skip.
  3. One decision-maker who answers questions the same day.

How this compares

US product design firms
4 to 12 weeks per prototype round; one firm's sample plan reaches an alpha prototype in 16 to 22 weeks1.
Online board assembly
As little as 4 to 5 days to assemble boards from finished design files2. That is boards only, and it needs the files first.
