METHOD FOR SPECIFYING CHANGE OF TOOL POSTURE, TOOL, AND TOOL CONTROL UNIT

摘要

PROBLEM TO BE SOLVED: To specify a change of a hand tool posture in a space.

SOLUTION: This method for specifying the change of the hand tool posture includes: a step of aligning an initial tool posture to a reference tool posture in order to specify at least a first posture vector A1of the tool, and in which at least one component of the first posture vector is specified by measuring a component of gravity acceleration in a prescribed axial direction of the tool 1; a step of defining the correction of the tool posture at the change of the actual posture of the tool 1 in the space by specifying the displacement of at least one angle of a newly-specified second posture vector A2of at least one temporally-succeeding posture vector, and in which at least one component of the second posture vector is specified after the change of the posture by measuring a component of gravity acceleration in the direction of a prescribed axis of the tool; and a step of providing information defined from the displacement of at least one angle related to an orientation of the tool 1.
