Most wheelchairs stop at the bottom of a staircase. The X12 does not even slow down.

Stairs, steep slopes, gravel paths, uneven
pavements, grass, cobblestones. The built environment is full of surfaces that
most mobility devices simply cannot handle. A standard wheelchair, even a
powered one, meets its limit quickly once it leaves a smooth floor. That
limitation has been accepted for decades as an engineering reality, not a
problem worth solving. The XSTO X12 treats it as exactly that, a problem, and
builds the solution directly into the machine itself.
The X12 runs on a hybrid chassis that combines
wheels, tracks, and quadruped joints into a single integrated system with
fourteen independent power units. On flat ground, four-wheel mode handles the
surface the way any powered wheelchair would, smoothly and efficiently. When
the terrain changes, the machine changes with it. Caterpillar mode engages for
rough outdoor surfaces, gravel, grass, and uneven paths. Crawler mode activates
for stairs, steps, and steep slopes, with tracks and wheels working together to
climb and descend in full control. The system reads what is ahead and switches
modes automatically, without the rider having to make a decision or even notice
the transition.
What makes the mode switching work in practice
rather than just in theory is the sensor layer running underneath it. LIDAR
maps the environment in real time, building a spatial picture of what is coming
before the wheels reach it. Gyroscopes read the chassis position continuously,
and a proprietary stabilization system called the Prow Stabilization System
adjusts posture automatically to maintain balance across every surface and
angle. The result is a machine that can perform 360-degree omnidirectional
steering on a slope, climb a staircase without assistance, and correct a
dangerous posture before the rider feels anything wrong. Voice alerts and real-time hazard warnings add an additional layer of awareness for the person
sitting in it.
The X12 is not a wheelchair with extra
features. It is a mobility robot that happens to carry a person. That
distinction matters because it changes who can go where, independently, without
planning a route around what the device cannot handle.
