Abstract
A method for tool calibration for a robotic tool includes providing a calibration device within a robot envelope. The calibration device includes a calibrating member positioned along a calibrating plane. The tool tip of the robotic tool is positioned to an initial position within the calibrating plane and position values of the robot face plate are obtained. The tool tip is rotated about the estimated or prior tool center point, the tool tip is again positioned within the calibrating plane, and further position values of the robot face plate are obtained. The actual tool center point is calculated from the obtained position values.
