Launch the Satellite

What’s a communication satellite?

EV3 Classroom-Programs 0-program en-gb

A communication satellite relays and amplifies radio waves from an Earth-centred orbit to various locations on Earth.

What are the advantages of using a communication satellite instead of an Earth-based antenna to communicate with Mars?


Launch the Satellite into a stable orbit by placing it inside of the marked area on the Challenge Mat. This will ensure that we can send a secure, unlimited, real-time flow of data to and from Earth.

Think about ways in which the robot could launch the Satellite into orbit.

Brainstorm ideas for solving the mission.


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

  • What are some ways in which the robot could navigate to the marked area?
  • Which type of motorised mechanism could be used to place the Satellite carefully and accurately within the marked area?

Build, program and test your robot.


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


Achievement Badges

The four levels of badges that you can earn for this mission are:

Platinum Badge
Every part of the Satellite rests inside of the marked area. You also went beyond the mission requirements by adding features to your design. Expect a promotion!

Gold Badge
Every part of the Satellite rests inside of the marked area. A high-speed link has been set up and mission control wants us to tell you that you’ve done a first-class job. Well done!

Silver Badge
Parts of the Satellite rest outside of the marked area, so while we have a link, it can be prone to problems and blackouts. You’ve done your best in a difficult situation, and we’re proud of you!

Bronze Badge
No part of the Satellite rests inside of the marked area but the satellite was launched into an undetermined location. The link is good enough for voice communications, so it will keep us going for now.

Go for it!


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

Mission Rules

Remember to follow these rules as you’re attempting to complete the mission:

  • Your robot must always start the mission from the base area.
  • Your robot must leave the base area before carrying out the mission.
  • A ‘successful robot return’ occurs when any part of the robot crosses over any part of the base area line.
  • You’re not allowed to touch your robot while it’s outside of the base area.
  • If you touch your robot while it’s entirely outside of the base area and it’s holding an object, the object must be returned to its original position, and you must begin the mission again.
