The first and second jaws of the wrist assembly are movably opposed, and the cables are configured such that applying tensions upon them cables produces rotation about a jaw axis. The wrist assembly may further include a hinge-rotary assembly to configured to provide rotation about a pitch axis and/or a roll axis. The wrist assembly may further include a fourth cable configured such that applying tensions upon the fourth cable and the opposing cable produces rotation about a pitch axis.
