You’ve maybe seen these already in restaurants? https://www.pudurobotics.com/product/detail/bellabot

Not sure I’ve seen them take drinks though, but definitely food.

Some of these robots are kind of "jittery" from what I've seen, I've seen soup delivered without spilling but it might not work well with drinks (not on "rough" terrain obviously)
