A current limiting device includes a current limiter to limit a current to be carried to a drive within a range of a limit value. The limit value is set to change according to a speed of the drive.

Current limiting device, robot system, and current limiting method

In a robotic surgical system, an operation unit includes a drive to assist an operation of an operator. A controller is configured or programmed to control the drive to exert a braking force when the operation on the operation unit is decelerated and/or accelerated.

Robotic surgical system, operator-side apparatus, and control method of robotic surgical system

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.

Robotic surgical system, control device of robotic surgical system, and control method of robotic surgical system

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.

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.
