Automated tool and workspace analysis
An automated tool installation and workspace analysis method determines an axis of a fastener in order to determine positioning a fastener actuating tool. A center of gravity of the fastener is determined. The axis of the fastener is calculated based in part on the center of gravity. Additionally, the axis of the fastener is calculated based on distances between vertices of the fastener and an initial assumed axis of the fastener. Once the axis of the fastener is determined, the positioning of the tool can be determined.
1. An automated tool installation and workspace analysis method comprising:
calculating a center of gravity of a fastener;
determining an axis of the fastener based at least partially on the center of gravity; and
determining positioning of a fastener actuating tool according to the axis of the fastener.
2. The method of claim 1 wherein determining the axis includes determining the axis based on a relationship between an initial axis and vertices of the fastener.
3. The method of claim 1 wherein determining the axis includes:
assuming an initial axis;
rotating the initial axis; and
adjusting the initial axis based on a relationship between the initial axis and vertices of the fastener.
4. The method of claim 3 wherein the assuming includes assuming an initial axis of L(c, V), where c is the center of gravity of the fastener, V is (1, 0, 0), and L is a line through c having direction V.
5. The method of claim 3 wherein the rotating includes rotating the initial axis in at least one direction about at least one axis.
6. The method of claim 4 wherein the relationship is a distance between each vertex and the line L(c, V).
7. The method of claim 1 further comprising rotating the tool about the axis to determine a tool-rotation envelope.
8. A graphical user interface that implements the method of claim 1 .
9. An automated tool installation end workspace analysis method comprising:
calculating a center of gravity of a fastener;
determining an axis of the fastener based at least partially on the center of gravity and thereby determining a position for an actuating tool to actuate said fastener as a function of said axis of the fastener;
positioning said actuating tool according to said position and determining rotation of said actuating tool within the workspace; and
evaluating said actuating tool based on said rotation of said actuating tool and said position.
10. The method of claim 9 wherein said actuating tool comprises a wrench that actuates said fastener by rotating so that said fastener fastens to the workspace.
