A head of a robot includes a head housing, a lace panel connected to the head housing, a mask moveably connected to the head housing, a mounting frame arranged within the head housing, a first servo connected to the mounting frame, and a first transmission mechanism to transmit motion from the first servo to the mask so as to move the mask between a first position where the mask covers the face panel and a second position where the mask is lifted to expose the face panel.

A deployment mechanism for selectively deploying and retracting an energizable member and/an insulative member relative to an end effector assembly of a surgical instrument includes one or more actuators, a clutch assembly, and a drive assembly. The clutch assembly is configured to couple to the actuator(s) to provide rotational motion in the first direction in response to such rotation of the actuator(s) and to decouple from the actuator(s) in response to rotation thereof in the second direction. The drive assembly is operably coupled to the clutch assembly and is configured to convert the rotational motion provided by the clutch assembly into longitudinal motion to translate the energizable member and/or insulative member from a storage position to a deployed position and to translate the energizable member and/or the insulative member from the deployed position back to the storage position.

A sucker rod reciprocating pump whose circular arc head is contiguous with a counterweight and is pivotably connected to the pitman arm, crank arm weight, and speed reducer. The pitman arm is substantially horizontal and the crank arm to wrist pin phase angle is about 70-90 degrees. Auxilliary counter weight extends from the head weight on a stinger and the head weights are adjustable. The head weight diameter is either constrained within the circular arc head's outer diameter or can be larger. The upper pitman bearings are outboard on the equalizer which is integral with the head. The center bearing of the head is outboard on the rectangular sampson post. The head counterweight increases permissible load on a speed reducer. This invention has embodiments for adjusting sampson post height and pitman arm length; and for changing the stroke length without removing the wrist pin from the crank weight hole.
