I forget to say the saucer has a shield.
Damn, that looks amazing!
How do you get these things done so fast???
Most of my modelling troubles are caused by proportions or by the fact that I lack some reference for the back of the robots. This saucer it's a symmetric model, I usually model it entirely, see what the final mesh would look like, and then I start working with a fraction, the UV was my only trouble, though is really simple, I couldn't decide which pattern choose for those glowing symbols, in the series there seems to be 2: one seen in the intro, a really simple patter that glows changing between colours, which seems to be used for emergency. The other is when the ship is latter reactivated, this time the patter is much more complex and it uses a yellow non-animated glow.
There is some UV missing here, but I didnt' want to make another bitmap, otherwise the pattern gets stretched and even more repetitive:

I also designed the inner platforms, so they could lower, as seen in the fourth episode, the upper part becomes something like a colosseum:

There is also the door where King Goru comes out, along the 4 beam turrets, but that's something that's only seen in the OVA, is very much like something of the moment that wouldn't be used otherwise. The Vacuum devices seemed to also be useless, they only could catch people, kids to be more exact, not even small cars.
AFAIK it was an alien craft that crashed on Earth after the DINO Empire went into Hibernation or something. Even THEY didn't know the origin or name for it.
They simply explored it and tried to figure out some tech and made enough repairs to get it semi-functional again (ie Hover, weaponry), and hooked up their Emporer's corpse up to it and he regenerated into a semi-cybernetic hybrid. Half Dino-Half Alien tech.
I think at that point he started to understand how the ship "worked" and it started to repair itself, but since I only saw that OVA once I don't remember.
Yes, that's very much like the info the OVA tells the viewer: "Alien Technology"
