Communicating closure effort for robotic surgical tools background

A method includes grasping a user input device in communication with a surgical tool of a robotic surgical system, the surgical tool including an end effector with opposing jaws, squeezing the user input device and thereby actuating a motor that closes the jaws and clamps down on tissue at a surgical site, and calculating with a computer system in communication with the surgical tool work completed by the motor to close the jaws and clamp down on the tissue. The computer system generates one or more effort indicators when the work completed by the motor meets or exceeds one or more predetermined work increments corresponding to operation of the motor, and communicates the one or more effort indicators to an operator.

Robot system and method of controlling robot system

A robot system includes a manipulating force detector configured to detect a manipulating force given to an operation end by an operator, a reaction-force detector configured to detect a reaction force given to a work end or a workpiece held by the work end, a system controller configured to generate an operating command of a master arm and generate an operating command of a slave arm based on the manipulating force and the reaction force, a master-side control part configured to control the master arm, and a slave-side control part configured to control the slave arm. The system controller has an exaggerated expresser configured to exaggeratedly present an operating feel to the operator who operates the operation end in a reaction-force sudden change state that is a state in which the reaction force changes rapidly with time.

VIDEO CONFIRMATION COMPUTER

A video confirmation computer for confirming video related to robot operation includes a storage unit and a processor. The storage unit stores information on the position of the electric motor that drives a link body of the robot received from the controller of the robot and information on the video obtained by a camera attached to the robot. The processor makes at least one of the video confirmation computer itself and a computer connected to the video confirmation computer display a model area and a video area side by side. In the model area, a two-dimensional or three-dimensional model reproducing the posture of the robot is displayed by computer graphics. In the video area, the video is displayed.

TORSIONAL SERIES ELASTIC ACTUATOR
20230219236 · 2023-07-13 ·

A rotary-type series elastic actuator (SEA) for use in robotic applications. The SEA including a motor, gear transmission assembly, spring assembly, and sensors. In one example, a robotic joint may include the SEA as well as two links coupled with each other at the joint assembly. The two links may be designated as input and output links. Each link may have a joint housing body which may be concentrically connected via a joint bearing so that they freely rotate against each other. The housing frame of the SEA may be fixed at the joint housing body of the input link while the output mount of the spring assembly of the SEA may be concentrically coupled with the joint housing body of the output link. The rotation of the motor rotor causes the rotation of the output link with respect to the input link plus spring deflection of the spring assembly. When an external force or torque are applied between the two links, a control action of a control loop may cause a rotation and motive force of the motor that lead to the deflection of the spring assembly to balance with the external force/torque and inertial force from body masses moving together with the links.

A safety switch device includes a first support member and a second support member which are formed so as to secure a mobile terminal, and a grip part to be grasped by an operator’s hand. The safety switch device includes an enable switch for transmitting a signal for permitting a robot to operate, and an emergency stop button for transmitting a signal for stopping the robot. The first support member and the second support member are formed so as to secure a plurality of types of mobile terminals having different sizes. The grip part is disposed at the center part of the shape of the back surface of the mobile terminal, which corresponds to the position of the center of gravity of the mobile terminal.

Charging device for charging a battery of an electrically operated motor vehicle

A charging apparatus for charging a battery of an electrically operable vehicle includes a plug element, a base element, and adjusting facility. The plug element is connectable to a corresponding, vehicle-side plug element of the motor vehicle and via which electrical energy is transferrable to the motor vehicle so as to charge the battery. The base element is connected to a current source and provides electrical energy from the current source for the plug element. Via the adjusting facility the plug element is movable relative to the base element in order to connect the plug element to the vehicle-side plug element, and via which an electrical connection is provided between the base element and the plug element. The adjusting facility has an overload protection via which the base element is electrically separated from the plug element in the event of a predetermined mechanical maximal load being exceeded.

ROBOT CONTROLLER

A robot controller includes a storage unit that stores load information including a mass and a center of gravity position of a load to be attached to a robot; a lead-through control unit that controls the robot comprising a sensor that detects an external force, based on the external force detected by the sensor and the load information stored in the storage unit; and a load suitability determining unit that determines whether or not the load information stored in the storage unit is suitable. In response to the load suitability determining unit determining that the load information has a possibility of being unsuitable, the lead-through control unit performs a restriction on a movement of the robot.

Robot comprising safety system ensuring stopping time and distance

A robot system and method for conditionally stopping a robot, wherein a maximum stopping time and/or distance are defined by a user or integrator through a user interface as safety limits based on the risk assessment. The method provides the continuous calculation of the time and/or distance, which the robot would need to stop under maximum motor torque and/or brake appliance. The robot is stopped or the speed of the robot is reduced, if the calculated time and/or distance exceeds the maximum limit values set by the user or integrator. The method may also be used to program or generate the trajectories of the robot as not to exceed the speed of the movement under the condition of keeping the set maximum stopping time and/or distance as defined by a use.
