Hilti publicly entered the occupational exoskeleton market in 2020 through a technology partnership with Ottobock, announcing the EXO-O1 as its first construction exoskeleton. Ottobock described the EXO-O1 as the first joint product, planned for launch in autumn 2020, and Hilti’s 2020 announcement called the EXO-O1 Hilti’s first foray into exoskeletons for the construction industry (see The Hilti Exo-01 Will Launch in Autumn 2020 With the Help of a Technology Partnership With Ottobock). Fast forward to 2026, and the EXO-O1 appears best treated as a legacy/previous-generation product rather than the current Hilti exoskeleton entry, because Hilti’s current category page lists EXO-S variants and EXO-T-22, while the EXO-O1 page remains separately accessible.
