Designing the next axis of motion for a collaborative robot on the Starfactory floor — kinematics, integration, safety case.

§01 · scope path
./scope.md redacted by intent. methodology stays.

nda_redacted

Placeholder. Project specifics — geometry, payload envelope, cell layout, sensor stack — are covered by NDA. This page documents the methodology and the engineering posture, not the artifact.

If you're a recruiter or hiring manager and need the full story, reach out and we can talk under appropriate cover.

§02 · approach path
./approach.md kinematics → integration → safety case.

three_loops_in_parallel

Placeholder. The work runs three loops simultaneously: a kinematics loop pinning down reach, payload, and dynamics; an integration loop fitting the axis into an existing cell without breaking adjacent operations; a safety case loop closing risk-assessment line items so it actually goes live.

posture

  1. — · placeholder

    Move at factory cadence.

    Placeholder. Decisions tied to a real cell on a real factory floor. Get to a defensible answer fast, then iterate. Perfect later.

  2. — · placeholder

    Cobot ≠ robot.

    Placeholder. Collaborative motion lives or dies on the safety case. Treating it as a kinematics-only problem is the failure mode I'm most watching for.

  3. — · placeholder

    Document the why.

    Placeholder. Every decision lands in the project log with the alternative considered and the reason it lost. Future-me and future-team need the trail.

§04 · status path
./STATE.md in progress. write-up after.

state_of_play

Placeholder. Project is active through Winter '26. A redacted post-mortem will land here once the term closes and approvals clear.
