Begin with the environment
Temperature, dust, vibration, moisture, power availability and operator constraints influence the architecture from the beginning. Designing these realities in late usually creates expensive rework.
Prototype to answer questions
A prototype should test the riskiest assumptions: sensing performance, power budget, communication range, mechanical fit or user workflow. Clear validation goals make every iteration more valuable.
Integration is a system discipline
Mechanical, electrical, embedded and software decisions interact. Interface definitions, configuration control and repeatable tests help prevent local improvements from creating system-level failures.
Evidence builds confidence
Documented tests, traceability and controlled revisions turn a demonstration into an engineering programme. Dependability is established through evidence, not presentation alone.
