The Repeat While Block repeats a single block or multiple blocks in a loop while or until a condition is true. It’s that simple.

To apply the Repeat While block to a program:

  1. Select whether to repeat the loop while or until a condition is true (=) , or to repeat the loop while or until the condition is false (≠). You can also select greater than/smaller than ( ≥ ,  ≤ )
  2. Add a condition to check.
  3. Insert a single block or multiple blocks to repeat in a loop.

Example code:

This loop will continue to run the Drive block in a turn, while the gyro sensor's readings show a value smaller than 50. Once it gets there - the loop will end and the robot wills top (Drive block with 0 power)
