An assembly for driving linear movement and roll movement of an elongate surgical tool, comprising: an elongate shaft comprising a central lumen extending along the shaft long axis; the elongate shaft comprising a plurality of apertures extending across walls of the elongate shaft and into the central lumen; a set of wheels positioned opposing each other and aligned on two sides of the central lumen, the set of wheels at least partially extending through the apertures beyond the walls of the elongate shaft and into the central lumen to contact an elongate surgical tool received therein; the set of wheels being coupled to the elongate shaft and configured to rotate with the elongate shaft as a single unit when the elongate shaft is rotated about the shaft long axis.

A surgical implant planning computer is connectable to a fluoroscopy imager, a marker tracking camera, and a robot having a robot base coupled to a robot arm that is movable by motors relative to the robot base. Operations include performing a registration setup mode that determines occurrence of a first condition indicating the marker tracking camera can observe to track reflective markers that are on a fluoroscopy registration fixture of the fluoroscopy imager, and determines occurrence of a second condition indicating the marker tracking camera can observe to track dynamic reference base markers attached to the robot arm and/or an end-effector connected to the robot arm. While both of the first and second conditions occur, operations are allowed to be performed to obtain a first intra-operative fluoroscopic image of a patient along a first plane and to obtain a second intra-operative fluoroscopic image of the patient along a second plane that is orthogonal to the first plane.

A modular robotic surgical system comprising: one or more tool-receiver units arranged as separate units, each tool-receiver unit operable to move a first elongate surgical tool received therein; a base comprising one or more motors, the base operable to move a second elongate surgical tool attached to the base or received therein, the base serving as a mounting for the one or more tool-receiver units; wherein each of the tool-receiver units is independently and interchangeably attachable to the base via a mechanical coupling interface which transfers one or more of: driving force for driving movement of the first elongate surgical tool received within the unit; electrical power supply to one or more components of the unit which drive movement of the first elongate surgical tool received within the unit; and data for controlling movement of the first elongate surgical tool received within the unit.

Provided is a support structure comprising a link member (a rod-like member), a clamp member disposed to surround the link member, and an elastic member disposed between the link member and the clamp member, the support structure supports the link member inside the clamp member via the elastic member, and the elastic member comprises a liquid impermeable material, and fills a space between the link member and the clamp member.

A system and method for installing bird flight diverters on wires, such as power lines and guy wires, is described. The system and method include the use of an unmanned aerial vehicle to place a robotic line crawler onto wires where the line crawler is configured to place bird flight diverters on the wire as the line crawler travels along the wire.

A magnetic biasing assembly comprising: an inner element comprising: a north polarised inner arc, and a south polarised inner arc disposed axially adjacent to the north polarised inner arc, and an outer element arranged to rotate relative to the inner element about an axis, the inner and outer elements being substantially concentric, the outer element comprising: a north polarised outer arc, and a south polarised outer arc disposed axially adjacent to the north polarised outer arc, wherein the inner and outer polarised arcs are arranged so as to have a stable equilibrium position and are arranged to exert a magnetic moment between the inner and outer elements in a direction towards the stable equilibrium position when the inner and outer elements are not in the stable equilibrium position.

An apparatus including a plurality of robot arm links movably connected to one another, where a first one of the robot arm links includes a frame, where the frame has a first end movably connected onto a second one of the robot arm links; and at least one vibration damper arrangement on the frame of the first robot arm link, where the at least one vibration damper arrangement includes at least one viscoelastic element connected to the frame of the first robot arm link by a connection such that, as the frame of the first robot arm link experiences vibrations, the at least one viscoelastic element dampens the vibrations in the frame of the first robot arm link based upon viscoelasticity and the connection of the at least one viscoelastic element to the frame of the first robot arm link.

In the link operating device, a distal-end-side link hub is connected to a proximal-end-side link hub so as to be changeable in position relative thereto via at least three link mechanisms. Each link mechanism includes a proximal-side end link member, a distal-side end link member, and a center link member. Position-controlling actuators and speed reduction mechanisms are provided to two or more of the link mechanisms. The proximal-side end link member includes a bent portion and a pair of rotational connection bodies disposed at one end of the bent portion. The speed reduction mechanism is disposed between the pair of rotational connection bodies, and includes an output shaft fixed to one of the rotational connection bodies, and an input shaft rotatably supported by the other one of the rotational connection bodies.

A robotic arm assembly includes a robotic arm including a link, a control rope operable with the link, and an attachment section, the control rope extending at least partially through the attachment section. The robotic arm assembly also includes an actuator pack attached to, or positioned adjacent to, the attachment section of the robotic arm, the actuator pack including an actuator, the actuator operable with the control rope and including a motor defining a pivot axis, the motor configured to move about the pivot axis to displace the control rope.

A parallel link robot includes a base having an axis, a movable portion movable along the axis so as to pick a workpiece in a first working region and place the workpiece in a second working region, and first, second and third arms arranged around the axis to form first, second, and third angles between the first, second and third arms. Each of the arms connects the base and the movable part to move the movable part along the axis. The third angle is less than 120 degrees. The first angle and the second angle are equal. The first and third arms are positioned on a side of the first working region with respect to the axis. The second arm is positioned on a side of the second working region with respect to the axis.
