Notebook Brainstorm Workflow

How your team fills out the engineering notebook brainstorm slides (drivetrain concepts, intake concepts, scoring concepts, defensive concepts, comparison tables) without copying from reference sites.

This is a process, not a list of rules. Walk it in order. The output is a notebook section that earns rubric credit because it shows real divergent thinking from your team — not transcribed content from somewhere else.

Why this matters

Judges read engineering notebooks to evaluate how the team thought, not just what the team built. The brainstorm section (gold, EDP Step 2) is where this is most visible. A brainstorm that looks copied from a reference site is the worst-case judging outcome — it reads as both lazy and dishonest at the same time.

The fix isn't to avoid reference sites — you're supposed to research as part of EDP Step 2. The fix is to use them at the right time and in the right way. That's what this workflow is for.

The four-round process

Total time: ~50 minutes per subsystem. Run separately for drivetrain, intake, scoring, defensive (slides 19, 20, 21, 22).

ROUND 1

Independent generation — pencil only

15 minutes · no devices, no internet, no reference sites

Each student on the team sketches 3 wild concepts for the subsystem on scratch paper. No filtering, no judgment. Bad ideas welcome — at this stage, “bad” is data.

Rules:
  • Chromebooks closed. Phones face-down.
  • Each student works alone for the first 10 minutes — no group discussion yet
  • Sketches must be on paper, not on a screen. Drawing forces thinking.
  • Last 5 minutes: students share their sketches with the team. Bad ideas stay in the pile.

Why this works: If you research first, your concepts are bounded by what you saw. If you sketch first, you generate ideas the references didn't prompt. That's where original thinking comes from.

ROUND 2

Reference research — add, don't replace

15 minutes · devices and reference sites allowed

Now the team can open spartandesignrobotics.org, watch community videos, look at past-season VEX teams' notebooks. The assignment: find one concept that none of your Round 1 sketches captured, and add it as a fourth concept on paper.

Rules:
  • Add concepts to the pile — do not replace what you already drew
  • If a reference site shows a concept similar to one you already have, that's confirmation, not duplication. Keep your sketch.
  • Note the source for any concept that came from research (you'll need this for Slide 23)
  • Sketch any new concept by hand, in your own style. Don't copy diagrams.

Why this works: Reference sites are most useful for catching what you missed, not for generating concepts in the first place. Your Round 1 sketches anchor your team's thinking. Round 2 expands it.

ROUND 3

Narrow to 3 · defend on paper

10 minutes · team discussion, no devices

From your now-4 concept pile, pick the 3 strongest. For each, write the pros and cons in your own words.

Rules:
  • Pros and cons must reference your team's specific situation — your strategy, your driver, your build skill, your motor budget
  • Generic statements like “simple to build” or “fast cycle time” don't earn rubric credit by themselves — they need to be specific to your team and the actual numbers you're weighing
  • Historical precedent: if any of the 3 concepts has a known precedent (a team that ran something similar), name them. If you don't know one, write “none known” honestly.

Why this works: Forcing pros/cons to be team-specific prevents copy-paste from reference sites. The website doesn't know your team. You do.

ROUND 4

Comparison-table numbers · calculate your own

15 minutes · calculator allowed, reference sites for formulas only

Slides 24–27 ask for an 8-criterion comparison table per subsystem. The cells must contain numbers your team calculated, not numbers from a reference page.

Rules:
  • Cycle time: estimate by mental simulation or by walking through the field with a stopwatch and a paper prototype
  • Top speed: calculate from gear ratio and wheel diameter. The website explains how to calculate. Your team picks the wheel and gearing, then computes the number.
  • Motor count: count against the 88W cap (R10a). Your team's budget, not a generic recommendation.
  • Weight: estimate from the parts list. Reference site weights are valid inputs to the math. The total is yours.
  • Build risk and complexity (1–5 scales): your team's honest assessment, given your build skill

Why this works: Numbers force ownership. If the cell says “cycle time: 8.2 seconds,” somebody had to compute that. The website can teach you the formula, but the answer in the cell is yours.

The comparison-analysis paragraph — this is the judging signal

Each comparison slide ends with a 3–4 sentence analysis. This paragraph is what judges read closely. Two patterns:

❌ What loses rubric credit “Concept B is the best because it has more advantages. The pros outweigh the cons. We picked B for our robot.”

Generic. No numbers. No team-specific reasoning. Reads as either copied or hand-waved.

✅ What earns rubric credit “Concept B leads on cycle time (8.2s vs 11.5s for A and 9.8s for C) because of its 4-motor green cartridge configuration, but it has the highest build risk (4/5) due to chain-driven center wheels. Concept A is slowest but simplest. Our emerging favorite is Concept B because cycle time matters most for our scoring-first strategy, and we believe the build risk is manageable with two of our experienced builders leading the chassis.”

Specific numbers. Names the trade-off. References the team's strategy and skill. Earns the credit.

Slide 23 (Research Notes) — the source-citation slide

This is the slide that documents your sources. It's where copying tends to happen most aggressively, because students think “research = transcribe.” The deck format actually prevents this if you enforce two things:

Field What students often write (low credit) What earns rubric credit
Lesson Applied to Our Design “Spartan guide says use 4WD.” “Spartan drivetrain-selection guide showed us that for our defensive-leaning strategy with a rookie driver, 4WD all-omni is the wrong starting pick. We'll start with center-traction.”
Source mix 5 rows, all from spartandesignrobotics.org Mix of Spartan guides + at least 2 non-Spartan sources: a 9 Motor Gang video, a competition match watched, a previous-season VEX team's Worlds notebook
Connection Generic statement about V5RC Specific design decision in your robot, traced back to that source

Coach instruction — copy-paste-ready

For each subsystem, your team will generate 4 concepts on paper before any of you opens spartandesignrobotics.org or any other site.

After you have your 4 paper concepts, you can use spartandesignrobotics.org and other sources to check your assumptions and add one additional concept you didn't think of. You'll then narrow to 3 for the slide.

Your comparison numbers must be calculated by your team — the website explains how to calculate, not what the answer is.

The “Lesson Applied to Our Design” column must reference your specific team strategy and skill — generic statements will not earn rubric credit.
