NASA is developing a compact rover designed to transmit data from the surface of an asteroid back to Earth, as illustrated in Figure P1.26. The rover will use a camera to take panoramic shots of the asteroid surface. The rover can position itself so that the camera can be pointed straight down at the surface or straight up at the sky. Sketch a block diagram illustrating how the micro rover can be positioned to point the camera in the desired direction. Assume that the pointing commands are relayed from the Earth to the micro rover and that the position of the camera is measured and relayed back to Earth.
