Robot buddy on Mars

How are robots controlled on Mars? Of course with code! 

This is one version of the game "Robot buddy on a mission", here the mission takes place on the planet Mars. If you are going to control a robot that is on a different planet than you, you need to write an algorithm about how it should act. Here, you'll get to try controlling a robot -  your buddy - along a path. 

In this game, you get to choose between being a programmer and a robot. You will practice using computers' language to communicate and give instructions to solve a specific problem. The instructions need to be correct, fullständiga, and in the right order.  

This is a digital version of the game Robot buddy! Click on the green flag and solve the code. The rules and a printable version of the game are available at the bottom of the page.

Instruction to supervisors

The aim of the game is to get an understanding of commands and algorithms, and how giving exact instructions is very crucial when writing code.

The time required: Around 20 minutes

  1. Divide the participants into groups (3-6 in each group). One of the participants will be the robot and the rest of the group should work together as programmers.
  2. Build a path using the numbered floor cards (0-10) according to the digital version of the exercise.
  3. Give the group a set of all the command cards except for the one that says "come up with your own command".
  4. Ask the groups to solve the task together - to get from the start position "0" to the end position "10". They should sort their command cards in the order that they'll give instructions to the robot during showtime. One command card can only be used once! 
  5. Each group gets to plan, test, and create their own program which is a sequence of commands by laying out their command cards in the order that they want. 
  6. Now it is show time where every group will control their robots by giving their commands. The programmers can read the sequences out loud, one command card at a time, and the robot will follow the instructions. Start on floor card "0". 
  7. Did everyone succeed in solving the task and getting from "0" to "10"? Did they have different approaches or did they all have the same solutions?

Rules

  • The robot should get from start position "0" to end position "10".
  • Programmerarna får bara använda vardera kommandokort en gång. The programmers are allowed to use the command cards one only.
  • The programmers don't necessarily have to use all the command cards. 

The commands

  • Move forward 1-4 steps
  • Go backward 1 step
  • Turn left
  • Turn right
  • Turn opposite direction

Increase the level of difficulty 

When everyone has completed the task, you can make it more difficult by taking away the command card that says "Move forward 1 step". Let the groups solve the task again without this card! 

Tips!

This game is inspired by Botrace, a game created by the teacher Niklas Gyulai who is a high school programming teacher. On Botrace's website,  you will find more challenges and different paths to build or draw on paper!
