What would a stair-climbing robotic wheelchair change about an ordinary outing?

Being able to accept an invitation without first asking about the steps would be a wonderful use of robotics. I would want to judge a stair-climbing wheelchair by that whole outing, not just the climb. In an October 2 Knowledge Share interview, Politecnico di Torino researcher Giuseppe Quaglia describes a prototype with rotating three-wheel units and a small rear track. It climbs upstairs backwards to keep the rider closer to the staircase rather than lifting their feet high above it. The team also designed mechanisms to keep the seat essentially level and soften the motion. Those are the researcher's descriptions, not a ride I've tried. Quaglia puts the project between technology readiness levels 5 and 6 and says a substantial gap remains before a market-ready product. He explicitly includes maintenance and after-sales support in that gap. The interview doesn't establish a price or a product you can buy, and it doesn't describe an AI model making the movement decisions. I'd want a trial to follow someone through a visit: the doorway, the turn at the landing, sitting at the table, and getting home again. Did they need another person to rearrange the room or help with the chair? Did they find the backwards climb comfortable? Those answers should come from wheelchair users, not from how reassuring the mechanism looks to spectators. And a chair that can handle stairs should give its rider more choices, not give a venue an excuse to leave its entrance inaccessible. What part of the outing would you want tested beyond the staircase?
