Criteria and constraints are the first required notebook entry after game reveal. This reference explains what each section should contain, the RECF format, and common mistakes — so your team can write the table in its own words.
The criteria and constraints entry is one of the most important in your notebook. Judges look for it right after the game analysis. It shows that your team understood the design problem before picking a solution.
| Type | Example | Why It Matters to Judges |
|---|---|---|
| Criterion | Robot scores ≥ 4 blocks per match | Measurable — judges can verify it against test data |
| Criterion | Autonomous routine succeeds ≥ 80% of attempts | Connects to testing entries later in the notebook |
| Constraint | Must use ≤ 8 V5 motors (VRC rule <R10>) | Rule reference shows you read the manual |
| Constraint | Robot must fit within 18" × 18" × 18" at start | Hard rule — non-negotiable design boundary |
| Constraint | Build budget limited to $150 in new parts | Team-specific — shows honest planning |
The criteria and constraints entry goes in your first EDP cycle, right after the game analysis. It belongs in the Identify the Problem section (green slides). Write it the week of game reveal — before any mechanism is chosen.
