A robot includes a first link, a driving device configured to cause the first link to rotate, a transmission member configured to transmit a rotation of the driving device, a first stopper provided on the first link, and a second stopper provided on the transmission member, wherein the first stopper and the second stopper are brought into contact with each other by a relative movement between the first link and the transmission member.

The present disclosure provides a joint limit detection method, apparatus, and robot with the same. The method includes: (a) determining a servo corresponding to a joint to be detected; (b) controlling an output shaft of the servo to rotate in a preset first direction; (c) measuring a rotational angle of the output shaft within a preset first duration; (d) determining whether the rotational angle of the output shaft is greater than a preset angle threshold; (e) repealing the steps (c) and (d) until the rotational angle of the output shaft is less than or equal to the preset angle threshold, if the rotational angle of the output shaft is greater than the angle threshold; and (f) determining a current rotational position of the output shaft as a first extreme position, if the rotational angle of the output shall is less than or equal to the angle threshold.

Provided are an operation control system and an operation control method for a movable member, which allow the movable range of the movable member to be utilized to the maximum while deformation of a mechanical element is prevented or reduced. An operation control system 1 includes: a movable member 26 having first mechanical elements 261, 262; an actuator 25 which moves the movable member 26 at a variable velocity; and a second mechanical element 27 which is fixed at a position so as to be capable of making contact with the first mechanical elements 261, 262. When the position and the velocity of the first mechanical element 261 or 262 depart from a predetermined allowable range in a two-dimensional coordinate system expressed by a position and a velocity, a stop instruction is outputted to the actuator 25.

A first robot and at least one further second robot are provided to run through a plurality of positioning ranges during operation. A dynamic behavior and/or a load characteristic value of the robot in at least one first positioning range can be adapted to a dynamic behavior and/or a load characteristic value in at least one second positioning range of the robot and/or a dynamic behavior and/or a load characteristic value of the first robot in at least one first positioning range is adapted to a dynamic behavior and/or a load characteristic value of the second robot in at least one second positioning range.

A control system and a method for controlling a surgical robotic system are provided. The surgical robotic system comprises a surgical robot arm. The surgical robot arm comprises a plurality of joints by which its configuration can be altered. An input is received which indicates a desired motion of the surgical robot arm when the surgical robotic system is operating in a mode in which the surgical robot arm is controlled in accordance with an objective. The objective is to control a particular part of the surgical robot arm to have a desired position and/or orientation. The control system determines that the desired motion of the surgical robot arm would cause a limit to be exceeded. In response to determining that the desired motion of the surgical robot arm would cause the limit to be exceeded, a control signal is generated for controlling the surgical robot arm, and the generated control signal is sent to the surgical robot arm in order to control the surgical robot arm. The control signal is generated, in response to determining that the desired motion of the surgical robot arm would cause the limit to be exceeded, such that: (i) movement of a first set of one or more of the joints of the surgical robot arm is restricted, and (ii) movement of a second set of one or more of the joints of the surgical robot arm is not restricted.
