Abstract
A robotic navigation system includes a handheld navigation unit associated with a frame of reference. The handheld navigation unit is moveable with respect to a plurality of axes and is configured to send movement signals based on movement of the handheld navigation unit. A controller is configured to receive the movement signals from the handheld navigation unit and determine control signals for the robot. The control signals are configured to incrementally move the robot with respect to a point of interest removed from the robot. The point of interest is removed from a fixed point on the robot as defined by assigned coordinates. The controller is further configured to reassign the assigned coordinates following each incremental movement of the robot.

A robotic navigation system configured to move a robot, the robotic navigation system comprising:
- a handheld navigation unit associated with a frame of reference, the handheld navigation unit moveable with respect to a plurality of axes, the handheld navigation unit configured to send movement signals based on movement of the handheld navigation unit;
- and
- a robot controller configured to receive the movement signals from the handheld navigation unit and determine robot control signals for the robot, the robot control signals configured to incrementally move the robot with respect to a point of interest removed from the robot, the point of interest removed from a fixed point on the robot as defined by assigned coordinates, the robot controller configured to reassign the assigned coordinates for the point of interest following each incremental movement of the robot.
A robotic system comprising:
- a robot including an arm and a mounting flange, the mounting flange moveable with respect to a point of interest that is decoupled from the robot, the point of interest defined by a set of coordinates relative to a point on the robot;
- a navigation unit positioned on the robot and associated with a frame of reference, the navigation unit moveable with respect to a plurality of axes, the navigation unit configured to send movement signals based on movement of the navigation unit;
- and
- a robot controller configured to receive the movement signals from the navigation unit, determine a current robot location, calculate a target location for the robot, transmit robot control signals configured to move the robot, and update the set of coordinates based on movement of the robot.
A method of controlling a robot comprising:
- receiving movement signals from a navigation unit;
- receiving offset distance signals from a sensor;
- determining a current robot location;
- calculating a target location for the robot relative to a current point of interest, the current point of interest decoupled from the robot and defined by assigned coordinates relative to a zero coordinate on the robot;
- transmitting robot control signals configured to move the robot;
- and
- reassign the assigned coordinates based on movement of the robot.
