How do we find our way in unfamiliar territory?
Thanks to sensors onboard the robot, we can determine in what condition we are.
We introduce programming with conditions ("if ... then ..." constructions) and do a quiz during the presentation to make sure that everyone understands this well enough.
In the assignments, the students will discover that Robo can solve difficult tasks by repetitively taking only small steps based on simple choices (the conditions).
This gives a first insight into the "divide and conquer" strategy in which you solve a problem by dividing it into smaller pieces that can be solved more easily.
For the fastest, there is a last assignment which requires an extra condition within the repeat loop (from 2 to 3 conditions).
