Create the code for the robot
In order for your robot to work, it needs a code that it executes. This code is written by you.
In this chapter, we will show you how to program effectively!
Explore block-based programming
Install the Spike program and program the robot to move forward 10 cm
Program the robot to draw a square
Write down on a piece of paper what you like and what you don't like
Blocky or Python? Explore and compare text-based programming
We achieved better results by programming in Python.
Advantages:
text can be edited quickly and shared easily
you don't have to search for blocks, you just have to write
Disadvantages:
it may be a disadvantage at first that you have to program in English, but you can get used to it
📝 Task:
Get to know Pybricks and write your first code on it, using which your robot describes a 10 centimeter square! After you try Pybricks, just like you did with blocky, write down what you like and what you don't so much!
Evolution of our Robot Code over the Years
old Blockly code - Kamilla

Tips for coding
We hid the complexity: we worked almost exclusively with drivebase, two actuator motor variables
From the commands, we only use straight, turn, curve, run_time, run_angle, wait, stop
Sometimes we also used parallel (wait=False) branches for speed
Name your circles: first write the year (write down the number of the round) then write who made them (name) and then the name of the circle (e.g.: Western collection).
This is how it should look: round2_kamo_western_collectionBuild your program code modularly, so that each circuit is independent of each other
Make a modular code
Everyone here worked on their own computer, with their own code.
We solved this by creating a program named"base.py". This program contains the correct settings and helper functions. From this program, we call the settings into the original code. This way, we don't interfere with or overwrite other people's settings.
Tipp: Unfortunately, we only realized before the competition that almost everyone was using different settings at first, and only then did we use a basic code module. You better be smarter than that!
Here you can find a diagram of our modular code

The Menu
For quick start, create a Menu function. This works so that when you start the program, round 1 appears, then when it is finished, round 2 comes, and so on until the last round.
You can switch between the programs with the right and left buttons and when the program ends, it automatically moves to the next round.
This is our "Menu" code.
Tip: Comment your code (ctrl+k+c) to make it clear!
Manage your program versions
This solution is for when you have created a good code but you can't store it. Many people save their programs on a pen drive, but it's not as efficient... as GitHub! GitHub is a version control program that stores your codes in the cloud.
This is much more efficient, because your codes are accessible from anywhere, from anywhere! We created a repository where everyone uploads their own codes and the changes can be tracked.
Since the codes are in the cloud, they can be restored even in the event of a zombie apocalypse!
