Nobody Asked for a Crab Chair

A futuristic mobility prototype replaces wheels with four articulating, light-up legs that bend independently and use LiDAR, collision radars and internal weight sensors to traverse uneven ground and climb stairs. Styled in a pastel, minimalist palette and unveiled at a mobility show, the “crab” chair looks striking and promising in demos, and its clever robotics and sensors showcase what engineering can imagine. It’s also explicitly a concept device - eye-catching, expensive, and unlikely to reach mass production - so the spectacle of it easily outpaces any realistic benefit to most users.

The core critique is that such high-gloss prototypes function as engineering “inspiration porn”: they headline innovation while siphoning talent, attention and funding away from practical, affordable solutions that would actually improve daily life. Rather than reinventing mobility for spectacle, priorities should include incremental but impactful fixes - lightweight, low-profile indoor/outdoor power chairs with customizable seating, safe shower chairs for step-in showers, and other cost-conscious refinements. The designers deserve credit for their creativity, but real progress requires getting out of corporate labs, listening to people with lived experience, and directing resources to scalable designs that solve everyday problems.
