Hah might need tougher tires. In my experience with my other rover robot dogs get real curious and run up close and bark but they usually don’t want to actually touch it because they’re too unsure of it.
Good you went with wheels instead of some kinda Boston dynamics deal, anything that looks like it has an Achilles seems to draw most of the attention of Kelpies and collies and other herding breeds. I knew one orchard roaming kelpie that would stare at the apple ladder foot for as long as it took until it moved so that it could bite the aluminium to herd it along.
