Digital vs. Physical: When to Prototype—and When to Simulate Andre Brown, Principal Engineer on Amazon’s Transportation Sustainability team (and former Shark/Dyson R&D lead), joins Rob to unpack the art of knowing which problems need cardboard, which need CFD, and which belong in VR. From drag-cutting truck fairings and crowd-sourced race-car CAD to Dyson’s “egg-inspired” robot vacuum, Andre shows why flat hierarchies, cross-discipline sketch-offs, and procedural design tools accelerate innovation. If you juggle human factors, aerodynamics, and sustainability, this episode is your playbook.Have ideas or just want to say hi, shoot me a note. Support the show
