Logic–Control

Control blocks are used to decide when, how and how often the robot should carry out an action.
They enable the robot to make choices, repeat tasks and pause at the right times.
Some of the important Control blocks are as follows:

Block Description

repeat 10 This block repeats the enclosed code a fixed number of times,
allowing the robot to execute actions repeatedly for a specified
count.

forever This block repeats the enclosed code endlessly until the program
stops. It’s ideal for tasks that should run without interruption, like
maintaining movement or sensors.

while The code inside this block keeps looping as long as the given
condition is true. It’s useful for continuous actions that depend on
real-time conditions.

This block pauses the program until a specified condition
wait until becomes true. Once the condition is met, the program resumes
its execution.

if then This block runs the code only when a specific condition is true. It’s
used to make the robot perform actions based on conditions that
must be met.

if then
This block checks a condition; if the condition is true, it runs one set

else of instructions. If false, it runs a different set, offering a decision-
making path.

if then

This block checks multiple conditions in order. It first checks if the
else if then first condition is true and runs the corresponding code. If not, it
checks the next condition and continues until all options have
been evaluated, running the final set of instructions if none are
else
true.
