Experiments

Deformable slopes

On deformable slopes, DreamWaQ's policy can rapidly adapt to uncertainties such as foot slipping.

Thick vegetation

When faced with thick vegetation, DreamWaQ's policy can adjust its joint power to overcome trapping due to the vegetation.

Pedestrian curb

DreamWaQ's policy can easily adapt its gait pattern to overcome a 15cm-height pedestrian curb

Stairs

On medium-rise stairs, DreamWaQ's policy enables a relatively small A1 robot to go down and up the stairs without any mode change

Outdoor Long-walk Course

The experiment was conducted after rainfall, which made the stairs more slippery. Moreover, some natural terrains also turned into mud, making the robot's feet stepped deeper on it.

The hiking course has an elevation gain of up to 22m from the robot's starting point and a maximum slope of up to 36 degree.
