Arrangement for Limiting Rotation, and Robot

An arrangement for limiting rotation, the arrangement including a base structure; a drive member rotatable relative to the base structure and having a drive feature; a stopping member having at least one driven feature, wherein the stopping member is arranged to be intermittently driven relative to the base structure between a plurality of discrete positions by a continuous rotation of the drive member and by cooperation between the drive feature and at least one driven feature, wherein the stopping member in a first end discrete position is arranged to limit rotation of the drive member in a first end position of a rotation range of the drive member; and a holding mechanism arranged to hold the stopping member in each discrete position, the holding mechanism being at least partly provided in the base structure.
