Mr. Rogers and the Droid factory?

I very well may be going crazy since I can find absolutely no reference to this on the internet, but I distinctly remember an odd episode, probably from the mid or late '80s, where Mr. Rogers goes to a factory that builds what appears to be R2 units (like R2-D2 of Star Wars fame). It seems bizarre but, upon arrival, I specifically remember him being greeted by one decked out with a tuxedo design on its chassis. Does anyone remember this? Did I dream this? If I didn't, does anyone have any idea what facility this was and why they made R2 clones? Unless given permission (to what end?), seems like there would've been some copyright/licensing issues with that.

This has been bugging me off and on for years and I can find no mention of such a weird occurence so if anyone remembers this visit or has any more information about that place, please chime in...
