Abstract
A robotic arm assembly includes a robotic arm and an instrument drive unit coupled to the robotic arm. The instrument drive unit is configured to provide five degrees of rotational freedom and includes a motor housing, motors supported in the motor housing and rotatable with the motor housing, and gear box assemblies coupled to the motors and configured to transmit drive power from the motors to a surgical instrument. The robotic arm may include a mounting arm that extends to an annulus for supporting a surgical port that selectively receives the surgical instrument.

A robotic arm assembly comprising:
- a robotic arm;
- an instrument drive unit configured to provide five degrees of rotational freedom coupled to the robotic arm and including:
- a motor housing;
- motors supported in the motor housing and rotatable with the motor housing;
- and
- gear box assemblies coupled to the motors and configured to transmit drive power from the motors to a surgical instrument.
A robotic arm assembly comprising:
- a robotic arm including a mounting arm that extends distally to an annulus;
- a surgical port coupled to the annulus;
- a sterile interface module;
- a surgical instrument coupled to the sterile interface module;
- and
- an instrument drive unit coupled to the sterile interface module and slidably movable along the robotic arm to translate the surgical instrument along the robotic arm and selectively advance the surgical instrument through the surgical port.
