What’s a satellite dish?

EV3 Classroom-Programs 0-program en-gb

A satellite dish is a type of antenna that uses radio waves to receive or transmit data. On a human mission to Mars, they’d be used to transmit messages between Earth and Mars.

What makes radio waves suitable for deep space communication?

Oh, no! The satellite dish is down.


We must get the Communications Station online quickly and effectively! We’ve been told that you and your team are the people that we should speak with about this.

Think about ways the robot could push the satellite dish into an upright position to get the Communications Station online.

Brainstorm ideas for solving the mission.


You can split the main task into smaller subtasks, and brainstorm answers to questions like:

  • What are some ways in which the robot could navigate to the Communications Station?
  • Can you think of some ways that the robot could push the satellite dish carefully and accurately into an upright position?

Build, program and test your robot.


Continue working on your robot until you’re ready to complete the mission.

Go for it!


Set up your robot in the base area and send it out for a judged attempt at this mission.

How did you do?


Which badge did you achieve? If you have enough time, you can try again for a better result.

Brilliant! The Communications Station is online… and you’re on to your next mission!
