In a ground-level ergonomics exhibition, an adult demonstrator stands still with both feet on a sole pressure board while wearing a teaching exoskeleton. A coach holds the empty training pack and its outer buckles against the back frame with both hands; the pack mouth is open. The hip, knee, and ankle connections follow the body, and one elbow sleeve covers the nearer arm. A bench on the right holds a shoulder-pad sample, webbing sample, stride ruler, short tape measure, and soft-tip inspection wand, with a long kit bag on the shelf below. A student watches from behind the rail with a guide card in both hands. Soft pencil-book colors distinguish metal, fabric, and wood.
