    摘要: This invention relates to establishing alignment or a desired orientational relationship between a master and a slave of a telerobotic system. The invention can advantageously be used in a surgical apparatus. A method of establishing a desired orientational relationship between a hand-held part of a master control and an end effector of an associated slave as viewed in an image displayed on a viewer is provided. The method includes causing the end effector to remain stationary, determining a current orientation of the end effector relative to a viewing end of an image capturing device operatively associated with the viewer and determining a desired corresponding orientation of the hand-held part of the master control relative to the viewer, at which orientation the desired orientational relationship between the hand-held part of the master control and the end effector would be established. The method further includes causing the hand-held part of the master control to be moved into the desired corresponding orientation. The invention extends to a control system arranged to cause the desired orientational relationship between the hand-held part of the master control and the end effector of the associated slave, as viewed in the displayed imaged on the viewer, to be established when operative control between the master control and the slave has been interrupted.
