Plus One
Prototype in design. Plus One is N+1 Labs' own open agent puck. Nothing has been built and no unit exists, so every value in this OPD is a design target or a design choice. Sizes are targets. Costs are not quoted yet.
Give your agent presence. Unlocked by design.
A physical button, voice and light for the agents you already use. Hold the plus to talk to your agent; the light ring shows when an agent needs you. Phone-ring size, it works with magnetic phone mounts and chargers.
- Start here: BUILDCARD.md, the summary, editions and what's not known yet.
- The whole thing in one file: opd.yaml. Feed it to an agent; see AGENTS.md.
- See it:
model/plus-one.glb,model/plus-one-exploded.glb,line/layout.glb(the 8-station line). - Layouts by volume: line/layouts/README.md. A bench cell for the first 100 units, a U cell for about 2,000 to 4,500 a month and a balanced MadeCell line for about 10,000, simulated from assumed values.
- Build an accessory: accessories/README.md. Everything about the base, a fit gauge, a template and starter prompts for your agent.
- Firmware: device/model.yaml, a draft device model under proposal 0001. Unlocked by design: USB-C and a BOOT button, nothing locked.
