A field test creates engineering evidence only when the result is tied to a known configuration and can be repeated under described conditions. A successful drive video is a demonstration, not complete validation.
Mission context
Surface, slope, temperature, payload, energy, speed and component state influence results. They should be recorded before the run together with the success criterion.
Engineering approach
HARDY uses a test → learn → iterate loop: record failure, define the change, update the configuration and repeat the relevant test.
What must be demonstrated
A minimum evidence package should support technical review.
- configuration identifier and method;
- primary measurement, image or video with context;
- conclusion, limit and design-change decision.
