A number of folks asked to see an updated picture of the Mars Rover electronics. This picture shows the top most electronics plate where most of the components are mounted. There are also electronics beneath the main electronics plate, including the laser, thermopile array sensor, laser relay and voltage regulator, main fuse, batteries, and main power switch. In addition, the camera is mounted on the front of the rover. In the chassis, there are eight ultrasonic sonar sensors, various resistors and capacitors, six motors, and six servos. There is a seventh servo in the mast head.
