Exoskeletons at Scale: Accelerating the Transition from R&D to Full-rate Production

The exoskeleton market is still in its infancy — but evolving quickly and ripe with opportunity. It’s a double-edged sword for OEMs who must identify the most impactful applications and crack the code on full-scale production, which presents a new set of challenges and considerations. Projects that seemed feasible during R&D and even LRIP can quickly become impossible at scale for a variety of reasons. So how can OEMs foresee (and avoid) issues that may arise as they ramp up production? Here, we’ll cover key tips and insights.
