Control of device including mechanical arms
A method of initializing the layout of one or more robotic arms controllable by an input object, comprising: entering a paused mode, in which control of movement of the robotic arms by the input object is paused; measuring an input object initialization layout, defined by the layout of at least one segment of the input object; actuating at least a portion of the robotic arms to match the input object initialization layout; and entering a controlled mode, in which movements of the input object control the robotic arms.
1. A method of controlling, using gesture recognition, an operation mode of a surgical system including at least one surgical arm insertable into the body, the method comprising:
detecting movement of at least one user body portion; and
controlling said at least one surgical arm based on the detected movement, wherein said controlling comprises controlling movement of said at least one surgical arm and/or transferring between modes of operation of said at least one surgical arm;
wherein controlling movement of said at least one surgical arm is by mapping measured user body portion movement to movement of at least a portion of said surgical arm; wherein said surgical arm comprises a plurality of portions sequentially coupled by joints, and wherein movement of a user's arm joint is mapped to movement of a corresponding surgical arm joint.
2. The method according to claim 1 , wherein said detecting comprises collecting images obtained by a motion detection camera.
3. The method according to claim 1 , wherein said detecting comprises collecting data from one or more motion sensors attached to the user.
4. The method according to claim 1 , wherein transferring between modes of operation comprises transferring between a pause mode in which surgical arm movement is paused, and a motion control mode in which the surgical arm moves according to detected user movements.
5. The method according to claim 1 , wherein said detecting comprises detecting movement of a leg and/or foot of the user.
6. The method according to claim 5 , wherein said detecting comprises detecting whether the user has lifted or lowered their knee and/or lifted or lowered their foot, and transferring between said modes of operation based on whether lifting or lowering were detected.
7. The method according to claim 1 , wherein said detecting comprises detecting movement of the user's arm, hand or fingers.
8. The method according to claim 1 , wherein said detecting comprises detecting whether said user is either standing or sitting.
9. The method according to claim 1 , comprising comparing said detected movement to stored user body portion positions.
10. The method according to claim 1 , further comprising selecting a timing and/or a speed in which the surgical arm is moved relative to a timing and/or a speed of the user movements.
11. The method according to claim 10 , comprising introducing a selected time delay between said user movements and corresponding surgical arm movement.
12. A surgical system comprising:
at least one surgical arm sized and shaped for insertion into a human body, the surgical arm comprising a plurality of sequentially coupled portions;
circuitry which detects movement of at least one user body portion; and
a controller configured, based on said detected movement of said at least one user body portion, for controlling movement of said at least one surgical arm and/or to transfer between modes of operation of said at least one surgical arm;
wherein controlling movement of said at least one surgical arm is by mapping measured user body portion movement to movement of at least a portion of said surgical arm; wherein said surgical arm comprises a plurality of portions sequentially coupled by joints, and wherein movement of a user's arm joint is mapped to movement of a corresponding surgical arm joint.
13. The surgical system according to claim 12 , wherein said circuitry comprises an imager.
14. The surgical system according to claim 12 , wherein said circuitry is configured to detect movement of a user's leg and/or foot and wherein said controller is configured, based on detection of said leg and/or foot movement, to transfer between said modes of operation.
15. The surgical system according to claim 12 , comprising a memory which stores one or more positions of one or more body portions of the user, and wherein said circuitry is configured to detect and determine said user movement by comparing to said stored body portion positions.
16. The surgical system according to claim 12 , wherein said system operation modes include at least two of: a pause mode in which surgical arm movement is paused, a motion control mode in which the surgical arm moves according to detected user movements, and a calibration mode in which a position of one or more of said sequentially coupled portions is initialized.
17. The surgical system according to claim 12 , wherein said system includes separate modes for different user postures, including sitting and standing.
18. The surgical system according to claim 12 , comprising a display which presents a representation of recorded user movement to the user to assist in carrying out a surgical procedure.
