Abstract: [Problem] To prevent sight of an observation target from being lost from a visual field of a monitor.
[Solution] A surgical arm system includes: an articulated arm in which a plurality of joints is rotatably connected by a plurality of links and which is capable of supporting an oblique-viewing endoscope at a tip; and a control system which controls the articulated arm to change a position and a posture of the oblique-viewing endoscope. The control system controls at least one of a rotation speed and a movement speed of the oblique-viewing endoscope in a visual field imaged through the oblique-viewing endoscope based on a position of the observation target in the visual field.

Abstract: [Object] To make it possible to perform gravity compensation with a more compact and lightweight configuration.
[Solution] There is provided a medical support arm apparatus including: an arm section including multiple joint sections, and configured such that a medical tool is provided on a front end; an actuator at least provided in a compensated joint section that is a target of gravity compensation among the joint sections, and including a torque sensor that detects a torque acting on the compensated joint section; and a gravity compensation mechanism that imparts to the compensated joint section a compensating torque in a direction that cancels out a load torque due to a self-weight of the arm section acting on the compensated joint section.
