Microsoft Kinect sensor is comprised of three sensors: an infrared projector, an infrared camera and RGB camera to capture high resolution 3D images. The Kinect sensor is a popular sensor for robotics due to the advanced capabilities it offers for the human-robot interaction. Microsoft Kinect sensor is a major innovation in robotics.

With the use of dedicated software, users can easily control the movements of a robot by using an Xbox Kinect and their bodies to dictate and instruct the desired modalities.
