Why this choice of terrain for Spot ?

[louislelay]

Hi everyone, I was wondering about the choice of terrain for the Spot locomotion environment by RAI. It seems to me that it’s one of the most complete environments available in the repo in terms of domain randomization for locomotion, but they decided not to take the usual approach of using rough terrain, opting instead for this semi-flat terrain. So if anyone would know why, I'd be interested! :)
