Systems and methods are provided for guiding movement of a tool. The system includes a tool and a manipulator. A guide handler obtains a target state for the tool and generates virtual constraints based on the target state and a current state of the tool. A constraint solver calculates a constraint force adapted to attract the tool toward the target state or repel the tool away from the target state based on the virtual constraints. A virtual simulator simulates dynamics of the tool in a virtual simulation based on the constraint force and input from one or more sensors, to output a commanded pose. The control system commands the manipulator to move the tool based on the commanded pose to thereby provide haptic feedback to the user that guides the user toward placing the tool at the target state or away from the target state.

Systems and methods for guiding movement of a tool

A method includes defining a virtual object and defining a first point and a second point associated with a virtual representation of a surgical tool. Movement of the virtual representation of the surgical tool corresponds to movement of the surgical tool in real space. The method includes controlling a robotic device coupled to the surgical tool to constrain the first point to the virtual object, determining that the first point is at a threshold position along the virtual object, and controlling the robotic device to guide the second point to the virtual object.

Systems and methods for providing haptic guidance

Systems and methods are provided for controlling robotic movement of a tool based on one or more virtual boundaries. The system comprises a tool and a manipulator to support the tool. A control system controls operation of the manipulator and movement of the tool based on a relationship between the tool and the one or more virtual boundaries associated with a target site. The control system includes a boundary handler to determine whether the tool is in compliance with the one or more virtual boundaries or is in violation of the one or more virtual boundaries.
