RegEx Guide

1. What is a RegEx?​

A Regular Expression, or RegEx, is a pattern (or filter). It accepts a certain set of characters and rejects the rest.​

• If a barcode does not correspond to the regular expression defined in the scanner acquisition filter, it is not retrieved by the drone​.
• If it corresponds, the drone retrieves the piece of information and flies to the next location.
