Concept artist Bradley W. Lewis designed the B1-SAL Probe Droid for the "Inspired By" Andor tie-in content in BioWare's 2011 massively multiplayer online role-playing game, Star Wars: The Old Republic. It's design was heavily inspired by the droid B2EMO from Disney+ television series Andor, which itself was designed by concept artist Jake Lunt Davies, with help from animatronic designer Josh Lee and creature designer Neal Scanlan.
Some Star Wars: The Old Republic players were mistakenly gifted a B1-SAL Probe Droid minipet instead of a JR-4 Recon Droid during the Star Wars Jedi: Survivor celebration login event that ran between April 28 and May 3, 2023, though this was later amended.
