Step 4 – Add Operator and Distance Sensor

Add an Operator and Distance Sensor block:

Select

Drag a inside the If/Then block.

This will tell the robot to perform a task if it scans something in front of it

Select

Drag a inside the Not block.

Change 50 mm to 260 mm.

The robot will now follow the upcoming blocks if it does not see a wall in front of it.
