Abstract: A device (1) for moving through a granular medium, the device comprising: a body (2); a rotatable part (4A, 4B) for rotational movement relative to the body about a rotational axis (6), wherein the rotatable part is externally-exposed and arranged to cause agitation of an adjacent portion of a granular medium in which the device is to be provided; a motor configured to cause the rotational movement of the rotatable part; and a protrusion (8) arranged to extend from the body and to limit rotational movement of the body about the rotational axis relative to the granular medium when the motor causes rotational movement of the rotatable part relative to the granular medium.
