By "in front", do you mean drawn on top of this actor?

i mean his rotation (the world has only 10x10 pixels so there are only 4 directions)

Rotation can be converted to horizontal and vertical vectors:

int r = getRotation()/90;
int dx = (1-r)%2;
int dy = (2-r)%2;

The space in front would then be:

int frontX = getX()+dx;
int frontY = getY()+dy;

If the space exists:

if (frontX >= 0 && frontX < 10 && frontY >= 0 && frontY < 10)

You can get what is in front with:

Actor actorInFront = getOneObjectAtOffset(dx, dy, Actor.class);

If an actor IS in front, you can remove it with:

if (actorInFront != null) getWorld().removeObject(actorInFront);
