a position with a user's wrist resting on a user's knee;

a position with the user's wrist resting on a portion of a user's thigh proximate the user's knee;

a position with a user's forearms held in a generally horizontal orientation; or

a position with a user's arms held outstretched in a generally horizontal orientation.

6. The method of claim 1 further comprising displaying a message on a display of the workstation, the message prompting the user to grasp and position the hand controller in the initialization position.

7. The method of claim 1 wherein determining the user ergonomic height comprises determining the user ergonomic height of the input device in response to actuation of a user actuable button by the user indicating that the hand controller is being held in the initialization position.

8. The method of claim 1 further comprising receiving user input of a change to the user ergonomic height of the input device based on user's preference and causing the platform to move vertically with respect to a base of the workstation to position the input device at the user directed ergonomic height.

9. The method of claim 8 further comprising receiving a user identification identifying the user and saving information associated with the user directed ergonomic height in a user database for the identified user.

10. The method of claim 1 wherein the input device comprises a right hand controller operable to receive input from a user's right hand and further comprising a left hand controller operable to receive input from a user's left hand, and wherein determining the user ergonomic height comprises determining the user ergonomic height based on the vertical position of at least one of the left or right hand controllers being positioned at the initialization position.

11. The method of claim 1 wherein the input device comprises a right hand controller operable to receive input from a user's right hand and further comprising a left hand controller operable to receive input from a user's left hand, and wherein determining the user ergonomic height comprises determining the user ergonomic height based on a combination of the vertical positions of the left and right hand controllers when positioned at respective initialization positions.

12. A method for positioning an input device of a workstation for use by a user in controlling a robotic surgery system, the input device being operable to generate input signals representing a position of a hand controller moveable within an input device workspace, the method comprising:

determining a vertical position of the hand controller within the input device workspace for an input signal received from the input device while a user's hand is grasping the hand controller in an initialization position defined with respect to user's body;

determining a user ergonomic height of the input device based on the vertical position of the hand controller at the initialization position, determining the user ergonomic height comprising determining the user ergonomic height of the input device in response to actuation of a user actuable button by the user indicating that the hand controller is being held in the initialization position; and

causing a platform of the workstation on which the input device is mounted to move vertically with respect to a base of the workstation to position the input device at the user ergonomic height.

13. The method of claim 12 wherein determining the user ergonomic height comprises determining a vertical offset to a current height of the input device that will produce a pre-defined vertical position of the hand controller within the input device workspace when the input device is positioned at the user ergonomic height.

14. The method of claim 13 wherein causing the platform to move vertically comprises causing the platform to move vertically over a vertical distance corresponding to the vertical offset.

15. The method of claim 13 wherein causing the platform to move vertically comprises:

causing the platform to move vertically in a direction associated with the vertical offset while successively receiving input signals from the input device representing a current position of the hand controller within the input device workspace; and

causing the platform to discontinue vertical movement when the current position of the hand controller in the input device workspace is proximate the pre-defined vertical position of hand controller.

16. The method of claim 12 wherein the initialization position comprises the user's hand grasping the hand controller in one of:

a position with a user's wrist resting on a user's knee;

a position with the user's wrist resting on a portion of a user's thigh proximate the user's knee;

a position with a user's forearms held in a generally horizontal orientation; or

a position with a user's arms held outstretched in a generally horizontal orientation.

17. The method of claim 12 further comprising displaying a message on a display of the workstation, the message prompting the user to grasp and position the hand controller in the initialization position.

18. The method of claim 12 further comprising receiving user input of a change to the user ergonomic height of the input device based on user's preference and causing the platform to move vertically with respect to a base of the workstation to position the input device at the user directed ergonomic height.

19. The method of claim 18 further comprising receiving a user identification identifying the user and saving information associated with the user directed ergonomic height in a user database for the identified user.

20.
