Zero actuators. Zero sensors. 70% obstacle clearance.
Researchers at Imperial College London developed a wheel that passively transforms when it hits an obstacle. No motors. No control system. The obstacle itself triggers the geometry to hook and climb.
Standard wheels clear about 25% of their diameter.
Whegs reach around 61% but sacrifice efficiency on flat terrain.
PaTS-Wheel achieves 70% while still rolling smoothly like a normal wheel. A single-part 3D-printed design.
Is passive mechanical intelligence enough for unstructured terrain or do legs still win?
