Data for: Talking to the twin: a systematic review of language interfaces, extended reality and digital twins for mobile robots

This dataset accompanies the systematic review "Talking to the twin: a systematic review of language interfaces, extended reality and digital twins for mobile robots". The review follows PRISMA 2020 and covers studies published from 2015 to 2026 that combine at least two of digital twins, extended reality (XR) and language interfaces on mobile robot platforms. Five sources were searched in October 2026: IEEE Xplore, ACM Digital Library, ScienceDirect, arXiv and OpenAlex. A tiered design was used: Tier 1 combined mobile platforms with one element, Tier 2 with two elements and Tier 3 with all three. The Tier 2 and Tier 3 searches returned 142 records (111 after removing duplicates), and 52 studies were included. Files S1_Screening_log_and_coding.xlsx (Supplementary Table S1 of the article)- PRISMA_counts: number of records at each stage of the PRISMA flow diagram, with exclusions by reason.- Screening_log: all 111 screened records with decision (Include/Exclude), stage, reason and exclusion category.- Included_coding: coding of the 52 included studies (robot type, digital twin level, XR mode and device, language role and technology, application domain and evaluation reported). S2_Search_records.xlsx- Bibliographic records returned by every search in every source, with a summary of counts per search. S3_Search_strings.txt- The exact search string run in each source, with fields, filters, search dates and number of records returned. README.txt- Description of every file and sheet. The files contain bibliographic data only (title, authors, year, venue, DOI or arXiv ID). Abstracts are not included because they are copyrighted by their publishers; every record can be retrieved through its DOI.
