1. A robotic surgical instrument, comprising:
an end-effector;
a tube extending along an axis between a proximal end and a distal end, the end effector pivotably coupled to the distal end of the tube and configured to pivot about a second axis perpendicular to the axis, a gear fixed to an outer surface of the proximal end of the tube; and
a second tube extending between a second proximal end and a second distal end and nested coaxially with the tube, the second distal end coupled with the end effector,
wherein rotation of the gear rotates the tube about the axis and pivots a working member of the end effector about the second axis.
