Wheelchairs to Climb Stairs in Near Future 🌐
I loved watching this video, and I'm impressed that medical #technology finally reached this level, though I wonder why we didn't get an invention like this sooner.

They reinvented the wheel
Quite brilliantly, in fact!
So good.
I think something like this would've been created sooner if it was practical. I see vulnerable wires, and the rolling resistance would be high.
Some existing wheelchairs even use massive rubber tires to limit the rolling resistance, despite the discomfort.

Hmmmm... Maybe, but from the video it seems like it could harden and soften on command.
