    Abstract: A method for assessing performance of a surgical instrument including one or more drivetrains is disclosed. The method includes sensing via one or more vibration sensors vibrations generated during operation of the one or more drivetrains of the surgical instrument, generating an output signal based on the sensed vibrations, filtering the output signal to generate a filtered signal of the sensed vibrations from the one or more drivetrains, processing the filtered signal to generate a processed signal of the sensed vibrations from the one or more drivetrains, and comparing predetermined threshold values for each of an acceptable status, a marginal status, and a critical status of the surgical instrument to corresponding values of the processed signal.

    Abstract: Systems and methods for calibration of a shaft of a surgical tool are provided. The tool includes an elongate shaft configured to be coupled to an electromechanical arm of a robotic surgical system and having an end effector coupled to a distal end thereof, the shaft being rotatable about its longitudinal axis. The tool also includes at least one target associated with the shaft and configured to be non-independently movable with respect to the shaft, wherein a position of the target is detected using at least one sensor disposed such that the shaft is able to move independently of the sensor. The detected position is used to determine a rotational angle of the shaft. This can involve accessing a memory on the tool or the system storing values related to a target position in association with corresponding values of a shaft rotation angle.

    Abstract: A robotic surgical system including a control system that controls the movement of a robotic arm coupled to a tool assembly having an end effector is described. The control system can also assist with controlling either the articulation or rotation of the end effector. Furthermore, the control system can detect and monitor one or more properties (e.g., articulation, rotation, etc.), which can be used by the control system to determine one or more appropriate movement parameters of either the robotic arm (e.g., velocity of movement) or the tool assembly coupled to the robotic arm (e.g., rotational speed of the end effector). The control system can detect any number of characteristics related to the end effector and use such information to control a variety of movement parameters associated with either the robotic arm or the tool assembly.

    Abstract: A robotic surgical system includes a robotic surgical assembly and a control assembly. The robotic surgical assembly includes a robotic actuation assembly, a processing device, and a first communication device. The robotic actuation assembly includes a robotic arm. The processing device is configured to instruct the robotic actuation assembly to perform a task based on a set of instructions. The first communication device is operable to transfer the set of instructions to the processing device. The control assembly includes a second communication device and a user input device. The second communication device is operable to communicate the set of instructions to the first communication device. The user input device assembly is configured to generate the set of instructions and send the set of instruction to the second communication device. At least a portion of the instructions are based on positioning of the user input device within three-dimensional space.
