Has anyone ever made working replicas of Badniks?

This might be one of the strangest threads on this forum, but then, it might not, too.  Building robots is a hobby for some people, a job for others, and when it comes to replicating iconic robots from literature, some people can do really impressive stuff.  But I haven’t been able to find replicas of the robots from this series.  Of course that makes sense for some; can’t exactly expect someone to pull off a metal fly that somehow actually can fly, but others, like Grounder, seem like they should be a great deal more doable.  With how gloriously obsessive Sonic fans get, and often, how technically proficient, it seems that someone should have done this by now, but still, I keep looking.

I imagine the Motobug would be the easiest one to do. Some flying ones could use a drone as a base, but you'd have to design the shell as not to obscure the fans.

The tricky part is getting the birds and squirrels to comply.
