Surgical instruments, control assemblies, and surgical systems facilitating manipulation and visualization

A surgical instrument, comprising:

• a housing;
• a shaft extending distally from the housing;
• an end effector assembly extending distally from the shaft, wherein the end effector assembly is configured to at least one of rotate or articulate relative to the housing;
• a motor disposed within the housing and operably coupled to the end effector assembly to at least one of rotate or articulate the end effector assembly relative to the housing;
• and
• a sensing assembly configured to sense movement of the housing relative to a reference position and to drive the motor to at least one of rotate or articulate of the end effector assembly relative to the housing based upon the sensed movement,
• wherein the sensing assembly is configured to operate in each of a standard mode, wherein movement of the housing effects at least one of rotation or articulation of the end effector assembly in a similar direction, and a reversed mode, wherein movement of the housing effects at least one of rotation or articulation of the end effector assembly in an opposite direction.
