Abstract: In a robotic surgical system, a controller is configured or programmed to change at least one of a level of an operation start assisting force, a level of an in-operation assisting force, or a level of a braking force based on a level change operation of an operator received by a level change receiver.

Abstract: A robotic surgical system includes a controller configured or programmed to calculate an operation speed signal, to calculate a first filtered signal, to calculate a limited signal, to calculate a second filtered signal, and calculate an output position signal based on the second filtered signal.

Abstract: A robot includes a lower arm mechanism having a first parallel link structure, an upper arm mechanism having a second parallel link structure, a base portion forming a lower side part of the first parallel link structure, a wrist portion forming a distal side part of the second parallel link structure, an intermediate connection portion forming an upper side part of the first parallel link structure and a proximal side part of the second parallel link structure, and an upper arm biasing unit for applying a biasing force against a rotating operation in a direction that the wrist portion descends to an upper arm configuring a lower side part of the second parallel link structure. According to the robot, the range of the portable mass of an object can be expanded without enlarging an arm drive motor and declining an arm operation speed.

Abstract: The present application relates a robot control device for controlling a robot and a robot system. The robot control device controls the robot selectively in a normal operating mode and in an overdrive mode. In the normal operating mode, the robot control device controls the robot to operate within an allowable range according to load applied to the robot. In the overdrive mode, the robot control device controls the robot to operate at high speed without operation of the robot being limited to the allowable range. To control the robot in the over drive mode, the robot control device interlockingly changes magnification scales, of a plurality of parameters that specify an operating speed of the robot, based on an overdrive magnification scale about a degree of a high speed operation of the robot in the overdrive mode.
