REM-02, also known as AreeEm-OhToo, represented a type of levitating droid engineered by Industrial Automaton for the purpose of examining atmospheric and soil conditions. Its compact size allowed for portability within a backpack, and its construction included self-preservation mechanisms to evade hazards during scout operations. The droid did not possess a vocabulator; although capable of environmental analysis, it lacked the capacity for insightful interpretation or recognition of observed phenomena. Consequently, REM-02 exclusively transmitted its survey data to an enviro-analyzer. Deeve, an operative of the Bureau of Scouting and Exploration Services, utilized REM-02 within his backpack to augment the remote resource scans he conducted on planets alongside his other equipment.
