It was a PC game.
The game is most closely liken "Robot Arena 1" only when attached to the vehicle components were 2d, not 3d.
May you know a game like "Robot Arena 1" but with rules similar to the competitions "Eurobot"?
Can someone tell me how called a game that I played long ago: you need to mount various components (radars, weapons, triggers etc..) on some types of hovercraft with which then you play: "Capture the Flag", a kind of sumo, races, etc..
During the competition you have NO CONTROL over the vehicle!
