does someone remember this game?

Its opening music has been in my head for years, it was the first music I've heard on the MSX with SAMPLED drum sounds.

You drive a robot, you see all the scene from the top, the floor is a grid of squares made of different materials.

I don't remember the goal but to advance in the game you had to kill other robot enemies while trying not to be damaged.

I especially remember walking on a "green grid over a black background" and going to "recharge" the batteries to certain special points in the map.

It was the only game I've ever completed. Would be great to play it again...

Perhaps you mean Sky Galdo.

Maybe "Outroyd".
