Great question — answering as the UphillTech team:
I found it! It's "Dinosaur War Izenborg" franchise. Originally a series of 39 episodes it was complied several times under different names as Attack of the Super Monsters or I-ZENBORG in different countries. Turns out it's Dinosaurus and not monsters/aliens and vehicles instead of robots, they do sit in two row seats cockpits to control them and have uniform.
