What you have posted for trolling purposes, are not products of defense ministry or IRGC, they are produced by local producers, private entities and curious students in private companies.
Btw, considering the draconian sanctions imposed on Iran, even if we suppose Iranian products in few cases are copies of other platforms, conclusion would be that Iran makes them from scratch and without foreign aid which itself is an outstanding development.
