    Here's another method - applying the quarternion of the camera to a vector (dist is how far away from the camera you want the object to be):

    var vec = new THREE.Vector3( 0, 0, -dist );
    vec.applyQuaternion( camera.quaternion );
    
    nanobot.position.copy( vec );
    

    Making the object a child of the camera didn't work for me, but this applyQuarternion method did (adapted from @WestLangley's answer here: Three.js: Get the Direction in which the Camera is Looking)

    You may wish to copy the rotation from the camera too, if you want it to always be facing the camera. And if you want to tweak the object's exact position after this, you can translateX, translateY etc.
