A rover crosses a sloped terrain course beside a measurement gantry. Compare a specification-based speed test with a stakeholder slope-and-endurance task. Passing verification alone does not ensure the operational need is met.
• 3D scene parts: Rover wheels / chassis; operational terrain course; test measurement gantry; battery / endurance meter; verification / validation evidence board. • Controls: Level-ground speed capability (0.5–2 m/s); Specified minimum speed (0.5–1.5 m/s); Operational slope angle (0–30 °); Stakeholder minimum operational speed (0.3–1.2 m/s); Battery endurance on level ground (10–40 min); Required task duration (10–30 min). • Live readouts: Level-ground verification pass (0/1); Operational speed proxy (m/s); Operational endurance proxy (min); Operational validation pass (0/1). • Guided experiments: Verified but unsuitable; Meet both criteria. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
Verification: level speed ≥ specified speed Burden = 1 + 2 sin(slope) Operational speed = motor speed / burden Endurance = level endurance / burden Validation: speed ≥ need AND endurance ≥ task duration
Representative systems-engineering teaching example. Equipment geometry and animation time are illustrative; this is not an equipment qualification, safety assessment or certification tool. Terrain and endurance are declared proxies, not traction, stability or battery physics. Verification and validation in real projects use broader evidence across the life cycle. Try the preset experiments, then compare the live readouts with the equations.
No. The stated model omits real qualification evidence and system-specific assumptions.
Verification and validation answer different questions.
