A robot joint configuration determining method, a robot using the same, and a computer readable storage medium are provided. The method includes: simulating a joint model of a first joint of the robot using first motion deviation data to obtain first result data; simulating the joint model using second motion deviation data to obtain second result data; taking the motion deviation data corresponding to one of the first result data and the second result data meeting one or more preset conditions as a target motion deviation data for the first joint; and determining type information of a reducer in a configuration information of the first joint based on the target motion deviation data. In the present disclosure, the motion deviation of the first joint that is relatively accurate can be obtained through the results of the two simulations.

A wireless connector includes: a first unit attached detachably from the outside of a first object; and a second unit attached detachably from the outside of a second object. The first unit includes a first housing to which a first transmission/reception part and a first connector part are secured, the first connector part being attached to the first object and transmitting a to-be-transmitted target between the first connector part and the first object. The second unit includes a second housing to which a second transmission/reception part and a second connector part are secured, the second connector part being attached to the second object and transmitting a to-be-transmitted target between the second connector part and the second object. The first transmission/reception part and the second transmission/reception part are arranged so as to be separated from each other and opposed to each other to wirelessly transmit the to-be-transmitted target.

A tool-holding arm includes a plurality of links and a tool coupling that removably secures a tool to the tool-holding arm. A first fluid spring provides a gravity-counteracting force to the tool-holding arm. A locking mechanism selectively locks the first fluid spring. An adjustment mechanism selectively adjusts an amount of the gravity-counteracting force provided by the first fluid spring.

Apparatus and methods for providing a robotic arm cart for transporting, delivering, and securing robotic arms to a surgical table having a tabletop on which a patient can be disposed are described herein. In some embodiments described herein an arm cart can contain multiple robotic arms. A robotic arm can be selected and moved from a storage position within the arm cart to a deployment position in which at least a portion of that robotic arm protrudes from the arm cart. A robotic arm in a deployment position can be coupled to a surgical table and decoupled from the arm cart.

A boot seal is detachably attached to a joint including: a drive link and link members; and a ball joint for linking them to be relatively rotatable or swivelable. The ball joint includes a ball shank having a shaft section fixed to the drive link and a ball section provided on one end of the shaft section and a holder that is fixed to an end section of each of the link members and that has a ball-receiving section for supporting the ball section in a state where the ball section is surrounded. A cover main body that covers the gap between the ball shank and the holder and that is formed of a flexible material includes through-holes through which the shaft section is made to pass, a slit that continuously extends between the through-holes, and a fastener opening and hermetically closing the slit along the entire length thereof.

A robot including an arm, a tool attached to the arm, a measurement fixture to be attached to a tip portion of the tool detachably, and a controller that recognizes a reference coordinate system used to control the arm, and that controls the arm. The controller stores data indicating a positional relationship between a tip of the tool and the measurement fixture or data to be used to calculate the positional relationship, and the controller calculates positional coordinates of the tip of the tool in the reference coordinate system based on position data of the measurement fixture and the positional relationship, where the position data is detected by using acquired image data from a visual sensor whose position is associated with the reference coordinate system.

A method for reducing vibration of a robot arm includes: a step of mounting at least one inertia actuator and at least one vibration signal capturing unit to a processing end of a robot arm; a step of applying the at least one vibration signal capturing unit to detect a vibration generated at the processing end of the robot arm so as to generate a vibration signal; a step of applying a central processing unit to evaluate the vibration signal and coordinates of the processing end of the robot arm so as to capture at least one set of corresponding control parameters for calculating at least one output force; and, a step of having the inertia actuator to apply the output force to the processing end of the robot arm for counteracting the vibration at the processing end of the robot arm.

A robot control device for a robot comprises a case and a connector board which is coupled to the case and includes a plurality of connectors which are disposed in a first region and a second region adjacent laterally to the first region. The plurality of the connectors may comprise a power connector which is disposed at a bottom of one of the first region or the second region and is coupled with a power supplier; and a processor connector which is disposed in a region different from that of the power supplier and is coupled with a processor.
