"And, you run also video because to fly this arm, you're relying mostly on some external camera views that may be coming from the arm itself or from the station"

This quote by Philippe Perrin is describing using video to manage a robotic arm. The robotic arm is being run remotely, and the operator is depending on external video camera views to control the arm. This implies that the operator is unable to physically see the arm, but rather need to rely on the video camera views to manage the arm. The video is essential to supply the operator with the required visual details to manage the arm. The video likewise permits the operator to monitor the arm's development and make changes as needed. Making use of video is important for the effective operation of the robotic arm, as it supplies the operator with the needed visual info to control the arm.
