## Abstract

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.

## Claims

### Claim 1

A method of providing feedback during surgery to a user controlling, via an input device, movement of a surgical device limb, the surgical device limb comprising at least two spaced apart joints, said method comprising:
identifying one or more disallowed anatomical regions in the patient's body in which movement of said surgical device limb should be restricted or avoided; said identifying based on calculation of a position and not on contact with tissue;
upon said user attempting movement of at least one of said joints of said surgical device limb to said one or more disallowed anatomical regions, providing feedback to said user via said input device, said feedback including at least one of force feedback, visual feedback, audible feedback.

### Claim 2 (depends on 1)

The method according to claim 1, wherein said identifying comprises collecting images by an imager inserted into the patient's body.

### Claim 3 (depends on 1)

The method according to claim 1, wherein said identifying comprises producing an anatomical map according to CT and/or MRI scans of the patient.

### Claim 4 (depends on 1)

The method according to claim 1, wherein said input device comprises avatar input arms and wherein said feedback is in the form of force resistance in response to the user's manipulation of said avatar input arms.

### Claim 5 (depends on 4)

The method according to claim 4, wherein said avatar input arm is shaped to reflect a shape of said surgical device limb.

### Claim 6 (depends on 1)

### Claim 7 (depends on 1)

The method according to claim 1, comprising filtering movements of said surgical device limb according to said identified disallowed anatomical regions.

### Claim 8 (depends on 7)

### Claim 12 (depends on 11)

The system according to claim 11, further comprising an imager insertable into the patient body, said imager configured to collect images for identifying said one or more boundary lines.

### Claim 13 (depends on 11)

### Claim 14 (depends on 11)

The system according to claim 11, wherein said surgical device comprises one or both of a pressure sensor and a motion sensor for indicating a position of said surgical device inside the patient's body.

### Claim 15 (depends on 11)

The system according to claim 11, wherein said memory stores a map of disallowed anatomical regions.

### Claim 16 (depends on 11)

The system according to claim 11, wherein said input device comprises one or more sensors for detecting user contact with said input device.

### Claim 17 (depends on 16)

The system according to claim 16, wherein said surgical device comprises one or more locks for limiting movement of said surgical device upon said detecting loss of contact or insufficient contact.

### Claim 18 (depends on 11)

The system according to claim 11, comprising a control mode in which movement of said surgical device is restricted to human freedom of movement.

### Claim 19 (depends on 11)

The system according to claim 11, wherein said controller is configured to filter signals received from said input device.

### Claim 20 (depends on 19)
