Lab: Scenarios and Pre-Prototype Checklist

Course 3 · Module 5 Type: Hands-on (scenarios · issues · optional fix · checklist) Suggested time: ~2.5–3 hours

Read first: Lesson · Pre-prototype checklist · ← TOC · ← M04 · M06 →

Keep these tabs open

Section titled “Keep these tabs open”
Document Why
Bitstream Studio run scenarios
Hackathon web-app optional ex06 / ex05
Enclosure design guide what to inspect
M04 export checklist sensor point names

Lab Goals

Section titled “Lab Goals”
  • Run at least 2 usage scenarios on the Twin
  • Log at least 3 issues or watch-outs
  • (Recommended) bind at least 1 firmware/telemetry state, or explain why it isn’t bound yet
  • Fill in pre-prototype-checklist.md, including the Top 3 fixes
  • (If time allows) fix 1 spot on the model and export a new GLB

Prerequisites

Section titled “Prerequisites”
  • Have a .glb in Bitstream Studio from M04
  • Have a lid-opening clip, or note that a camera angle is used as a temporary substitute
  • An evidence folder, lab-notes/ or equivalent

Lab A — Write scenarios before you click (required)

Section titled “Lab A — Write scenarios before you click (required)”

Choose at least 2 scenarios from Lesson §2.1 — S3 (Lid service) is required, plus one more.

Scenario ID Who / action Expected result
S3 — Lid service
(second)

Pass when: a teammate reads the table and can run it again without asking further questions

Lab B — Run scenarios and log issues (required)

Section titled “Lab B — Run scenarios and log issues (required)”

For each scenario:

  1. Perform the action
  2. Note expected vs actual
  3. Take at least 1 screenshot per scenario
  4. Accumulate the issue list (target ≥ 3 total, across all scenarios)

Pass when: both scenarios are fully logged, with ≥ 3 issues

Lab C — Bind data or document the gap (required)

Section titled “Lab C — Bind data or document the gap (required)”

Choose one path:

Option What to do
C1 Link a Simulator/Board · open ex06 or ex05 · capture it alongside the Twin
C2 Bind a state in the Studio (colour/clip/highlight) to an event or mode
C3 Not bindable yet — write the reason + a plan for M06 into the checklist

Pass when: there is image evidence or a clearly written reason in the checklist

Lab D — Fill pre-prototype checklist (required)

Section titled “Lab D — Fill pre-prototype checklist (required)”
  1. Fill in every main row in pre-prototype-checklist.md
  2. Write the Top 3 design fixes before print
  3. Decide: Ready to print / Not ready (state the blockers)

Pass when: the Top 3 is not empty, and a Ready/Not ready decision is recorded

Lab E — Optional quick fix loop

Section titled “Lab E — Optional quick fix loop”
  1. Pick 1 issue from the Top 3
  2. Fix it in Blender
  3. Export a GLB per M04
  4. Import it again · quickly re-run S3
  5. Note whether it improved

Deliverables checklist

Section titled “Deliverables checklist”
  • 2 scenarios + screenshots
  • ≥ 3 issues / watch-outs
  • Pre-prototype checklist + Top 3 fixes
  • Lab C evidence or a written gap
  • (optional) a new GLB after a fix

Troubleshooting

Section titled “Troubleshooting”
Symptom What to try
You don’t know what problems to look for Use the Risk table in Lesson §3 · turn on Wireframe while opening the lid
No sensor data stream Use C3 · or run only S1–S3/S5, and plan the data binding for M06
No lid-opening clip Rotate the camera to simulate opening it · note that you need to go back to M03
The checklist passes everything too quickly Have a teammate review S3 again — it usually catches a missed hinge or port
The model’s scale breaks after a fix Apply Scale · check the Unit setting · export the whole file again
