How it works
So natural, you feel free
No resistance. WIM S moves with your body, adding power only when you need it.
A back-drivable hip robot reads your stride and boosts each step, adding power only when you need it.
The modes are Air, Aqua, Hiking and Care.
Four assist levels share the same 6 Nm maximum.
