Abstract
Abstract Methods and apparatuses for assemblying, handling, and fabrication are disclosed in which targets are used on objects. The targets can be specifically applied to the object, or can be an otherwise normal feature of the object. Conveniently, the targets are removable from the object or covered by another object during an assemblying process. One or more robots and imaging devices for the targets are used. The robots can be used to handle or assemble a part, or a fixture may be used in conjunction with the robots. Conveniently, the CAD design system is used in designing the targets as well as for the assembly process using the targets. A plurality of targets can also be used to monitor and inspect a forming process such as on a sheet panel.

Claim 3
Dependent Claim
27 words
A method for controlling an assembly process as claimed in claim 1 and further including the step of grasping the second part with a second movable robot.
Claim 4
Dependent Claim
25 words
A method for controlling an assembly process as claimed in claim 2 and further including the steps of affixing additional targets to the second robot.
Claim 5
Dependent Claim
45 words
A method for controlling an assembly process as claimed in claim 3 wherein said locating steps includes the mounting of the TV camera on the first-mentioned robot, and the further step of mounting a second TV camera at a known position on the second robot.
Claim 6
Dependent Claim
65 words
A method for controlling an assembly process as claimed in claim 4 wherein the first-mentioned targets are affixed to the first-mentioned robot, and wherein the determining step includes the determining of the position of the first-mentioned robot using the targets thereon and the second TV camera, and the determining of the position of the second robot using the targets thereon and the first-mentioned TV camera.
