SkinnedMesh cannot be placed/rotated

Description of the problem

I am getting a SkinnedMesh from a Collada scene (in the callback) and setting translation and rotation on it have no affect. Adding it to a dedicated scene object does not have the desired effect neither.

class RobotClass extends Object3D {

public loadingCompleted(collada: ColladaModel) {
    const scene = new Scene();
    this.add(scene);
    scene.rotateX(-1.57); // affects all objects in the scene but the robot
    const robot = colladaScene.getObjectByName(this.params.name) as SkinnedMesh; // object is indeed a skinned mesh
    robot.rotateX(.57)
   // updateMatrix/updateMatrixWorld have not effects
    scene.add(robot);
}
}

Any idea how I can resolve this issue? When I add the whole collada.scene object positioning is not an issue.

PS: I am using Typescript bindings
