I have deployed robotics in industrial applications and they are surprisingly robust.
Critical joints and components can be shielded from debris or have “puffers” strategically placed to prevent dust and dirt from being a problem.
Okay fine. We will just pour an oil slick in front of it. LOL Just kidding! I was just thinking about my Wile E. Coyote childhood. I did watch the video where it drove through the snow into the parking lot. Impressive.
What about spike strips? Yea yea yea, I know it will just jump over them, as demonstrated on the video. =)
