A closer look at the collection

Before departure, keep an offline copy of your accommodation address in both English and Chinese. Record an alternative way to reach your host if your usual messaging app is unavailable.

Send every supplier the same specification revision. Ask them to separate unit price, tooling, sample cost, packaging and lead time so that quotations can be compared on the same basis.

For each technical claim, record the original source, publication date and a short quotation for internal checking. Separate an author’s result from your interpretation, and verify any redistribution rights before including the full source.

Suggested columns: supplier, specification revision, unit price, minimum quantity, tooling, sample terms, lead time, quotation date, supporting evidence and unresolved questions. Mark missing information explicitly rather than treating it as zero.

Acceptance example: from a clean documented environment, launch the world and robot, set an initial pose, send a goal and record the outcome. Save parameter versions alongside the result; one successful video does not establish repeatability.

Acceptance example: load a fixed planning scene, choose a documented start state and goal, then record planning success and collision checks. Document joint limits, planner settings and known failure cases.
