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.
Mars Rover – Main Electronics Plate – From left to right, top to bottom: xbee radio, voltage sensor, voltage booster for camera, Arduino Mega, servo controller, power rail and motor controller.
very nicely executed project! what type of engines are you using for wheels?
good luck in future projects!
Thank you. We used 12volt Precision Gear Motors on this rover.
Thanks for the reply. May I ask how long do they last in your experience? Have you ever considered something more reliable, like maxon?
Would it be possible for you to give us enthusiasts a list down of the hardware with prices or maybe a budget plan?
Could you please send me the code that you wrote to controll the rover?
