I was notified by a visitor about this page:
On that page I wrote about the Vehicle Factory:
As far as I remember I got that from the original user manual. However, the attentive visitor mentioned that a Vehicel Factory cannot produce robots. I haven't played Z in a while but I think there were situations where it could. I am not sure though.You can identify a vehicle factory by the wide door in the front. It can produce all types of robots, vehicles and cannons depending on the level you are playing.
Who can shed light into this question?
