Surgical instrument engagement detection

A surgical robot comprising a robot arm base connected to a distal robot arm link via a series of intermediate articulated robot arm links. A robot arm interface is attached to the distal robot arm link. ... Cambridge Medical Robotics Limited

Rotary encoder

A device for sensing the relative rotary position of first and second parts about a rotation axis, the device comprising a follower constrained to move on a first track fast with the first part and on a second track fast with the second part, the first track being linear and the second track comprising a plurality of circular arcs and at least one transition section connecting one of the circular arcs to another, the tracks being arranged so as to convert relative rotation of the parts into linear motion of the follower, wherein the second track is generally spiral, each circular arc is of constant radius about the rotation axis and the first track is perpendicular to the rotation axis.. . ... Cambridge Medical Robotics Limited

Gear packaging for robot arms

A robot arm comprising a joint mechanism for articulating one limb (310) of the arm relative to another limb (311) of the arm about two non-parallel rotation axes (20, 21), the mechanism comprising: an intermediate carrier (28) attached to a first one of the limbs by a first revolute joint having a first rotation axis and to a second one of the limbs by a second revolute joint having a second rotation axis; a first drive gear (33) disposed about the first rotation axis and fast with the carrier, whereby rotation of the carrier relative to the first limb about the first rotation axis can be driven; a second drive gear (37) disposed about the second rotation axis and fast with the second one of the limbs, whereby rotation of the second one of the limbs about the second rotation axis relative to the carrier can be driven; at least one of the first and second drive gears being a sector gear.. . ... Cambridge Medical Robotics Limited

Characterising robot environments

A method for characterising the environment of a robot, the robot having a flexible arm having a plurality of joints, a datum carried by the arm, a plurality of drivers arranged to drive the joints to move and a plurality of position sensors for sensing the position of each of the joints, the method comprising: contacting the datum carried by the arm with a first datum on a second robot in the environment of the first robot, wherein the second robot has a flexible arm having a plurality of joints, and a plurality of drivers arranged to drive those joints to move; calculating in dependence on the outputs of the position sensors a distance between a reference location defined in a frame of reference local to the robot and the first datum; and controlling the drivers to reconfigure the first arm in dependence on at least the calculated distance.. . ... Cambridge Medical Robotics Limited

Surgical robot driving mechanism

A surgical robot comprising a surgical robot arm and a surgical instrument. The surgical robot arm terminates at its distal end in a drive assembly comprising a first drive interface element. ... Cambridge Medical Robotics Limited

Gear packaging for robotic joints

A robot arm comprising a first arm segment and a second arm segment coupled to each other by a first revolute joint having a first rotation axis and a second revolute joint having a second rotation axis non-parallel to the first rotation axis, and a joint mechanism for articulating the first arm segment relative to the second arm segment about the first and second rotation axes, the joint mechanism comprising: a first driven gear disposed about an axle coincident with the first rotation axis, the axle being fast with a first arm segment of the robot arm; a second driven gear disposed about the second rotation axis and fast with a second arm segment of the robot arm and fast with the first driven gear about the first rotation axis; a first drive gear configured to drive the first driven gear to rotate about the axle, the first drive gear being arranged to engage the first driven gear; a second drive gear for driving the second driven gear to rotate about the second rotation axis; and an intermediary gear arrangement arranged to engage the second drive gear and the second driven gear and being disposed about the first rotation axis, whereby rotation of the intermediary gear arrangement relative to the first arm segment about the first rotation axis can be driven.. . ... Cambridge Medical Robotics Limited

Robot tool retraction

A robot comprising: a base; a flexible arm extending from the base and having: a plurality of joints whereby the configuration of the arm can be altered, a plurality of drivers arranged to drive the joints to move, and an attachment structure for attaching a tool to the arm; and a control unit configured to control the drivers and to receive inputs from sensors, and operable in a mode in which, whilst a tool is attached to the attachment structure and captive in a port, it: (i) controls the drivers to permit the arm to be reconfigured by the action of an external force applied to the arm so as to cause the tool to be retracted from the port along a longitudinal axis of the tool; and (ii) on receiving sensor input indicating that the arm has been reconfigured so as to cause the tool to be retracted from the port along a longitudinal axis of the tool, controls the drivers to reconfigure the arm so as to agitate the tool transverse to the longitudinal axis of the tool.. . ...
