A '''bottom crawler''' is an [[underwater]] exploration and recovery vehicle.<ref>{{Cite journal |last=Watanabe |first=Keisuke |date=2023 |title=Tank Experiment of a Seabed Walking Platform Model for Subsea Mining Exploration |url=https://www.jstage.jst.go.jp/article/jrnal/9/4/9_4/_article |journal=Journal of Robotics, Networking and Artificial Life |volume=9 |issue=4 |pages=326–330 |doi=10.57417/jrnal.9.4_326}}</ref> It is designed to sink to the bottom of a body of water, where it moves about using traction against the bottom with [[wheel]]s or [[Continuous track|tracks]]. It is usually tethered to a surface ship by cables providing power, control, video, and lifting capabilities, but this is not essential.

Such devices have been proposed for use in recovering deep seabed minerals, such as [[manganese nodules]].

These also have been considered since the late 1960s for use in offshore [[oil exploration]] and production in extremely deep water, but practical devices have used other technologies from the sea surface, such as moored barges and [[tension leg platform]]s.
