[Object] To make the vertical and horizontal directions of an endoscope image and the vertical and horizontal directions of the screen of a monitor coincide with each other without spoiling the effective region of the endoscope image. [Solution] A control device of an endoscope system according to the present disclosure includes: a scope rotation angle acquiring section that acquires a scope rotation angle, around an axis in an insertion direction, of a scope including an objective lens to be inserted in a body; and a rotation angle control section that controls a rotation angle, around an optical axis center, of an image sensor that captures an image provided by the scope, on the basis of the scope rotation angle.

[Object] To enable greater compactness and also to be capable of preventing breakdown more reliably. [Solution] Provided is an actuator, including: a motor; and a reduction gear having a breakdown torque that is less than a starting torque of the motor. A limit value in accordance with the breakdown torque of the reduction gear is set with respect to a control value for driving the motor.

A robot arm apparatus according to the present disclosure includes: one or a plurality of a joint unit that joins a plurality of links constituting a multi-link structure; an acquisition unit that acquires an on-screen enlargement factor of a subject imaged by an imaging unit attached to the multi-link structure; and a driving control unit that controls driving of the joint unit based on a state of the joint unit and the enlargement factor.
摘要:
[Object] To enable further suppression of the movement amount of an arm section when switching states. [Solution] There is provided a control apparatus configured to execute a current tracking control on a basis of a measurement value of a torque sensor of an actuator provided in at least one of multiple joint sections included in an arm section of a medical support arm apparatus, the current tracking control causing a motor of the actuator to output torque by which a position and an attitude of the arm section are maintained, and switch a first state in which the motor is driven in accordance with a predetermined control method, and a second state in which the joint section is locked using a brake of the actuator.
摘要:
[Object] To calibrate an internal model more efficiently and more precisely [Solution] Provided is a robot arm apparatus including: an arm unit made up of a plurality of links joined by one or a plurality of a joint unit, the arm unit being connectable to an imaging unit. An internal model including at least geometric information about the arm unit and focus position information about the imaging unit is updated using internal model information acquired in a state in which the imaging unit is pointed at a reference point in real space.
摘要:
To make it possible to configure a medical support arm apparatus which does not impair operability for the surgeon, and which is also compact. Provided is a medical support arm apparatus including: an arm section configured so that a medical tool is provided on a front end, and movable axes are arranged so that the arm section has at least six degrees of freedom. Among the movable axes, a movable axis provided on the front end side that prescribes an attitude of the medical tool is a passive axis that rotates by following an external force, and at least one axis provided on a base end side that prescribes a position of the medical tool is a drive axis driven by an actuator.
摘要:
There is provided a medical support arm device including a multi-joint arm having a distal end configured to host a medical device, said multi-joint arm configured to have a higher degree of freedom than a degree of freedom necessary for controlling a spatial position and pointing direction of the medical device. The multi-joint arm is configured to controllably displace at least one of a plurality of joints of the multi-joint arm while the spatial position and the pointing direction of the medical device are controlled.
