LASER SYSTEM HMI STEPS WITH IN-SITU MEASUREMENT, LIVE VIDEO, IMAGE PROCESSING AND CAD ENTITY SCALING AND TRANSLATION.

My copyright extends, but is not limited to, the features below.

Sequential stepwise user interface guidance of the operator as to what "function" is to be performed next. I use a numeric system which greys out all invalid inputs and highlights the next step in using the software for laser micromachining. Initially the HMI was for diamond marking but the exact same software can be used to micromachine many features on a worksurface. For example, Harvard robotics used the LMS550 software to drill composites and other materials to make their microprossorless flying insect. (IEEE Spectrum, 2008)

Also copyrighted is the WYSIWYG CAD ENTITIES that appear as RED OVERLAYS on the LIVE VIDEO depicting the exact positioning of the mark (or any other feature) as it will appear on the worksurface or can be measured via coaxial or offset, microscope or stereoscope.

Also part of the copyright is the combination of both visible and the laser wavelengths as if the operator were looking at an actual live video microscope (which they are via the optics and beam path.) Although Potomac Photonics was the first to combine the visible and laser wavelengths for micromachining, my copyright disallows any company from using a WYSIWYG set of overlays for positioning, scaling or measuring features within the HMI on their live video display without my consent.

It took me many, many months of Visual C++ API creation and modification along with many, many years to perfect this design and the Visual Basic HMI so that it was not only safe and failure free but that itwas maintainable when we changed hardware vendors...don't even get me started on Microsoft and DirectX....

I’m glad that cooperative robots are working especially the ones that can give massages! However, in the articles that I read, the robot is programmed for a specific task. This to be expected but what of the unmentioned issues of gripper replacement for part dimensions, programmability and placement of the integrated machine vision and capability for programmability of one robot or cobot by non-technical users in the field for multiple functions?
These are the issues I’ve faced while attempting to commoditize 3axis Excimer Laser micro machining systems for non-technical users.
To get a robot to perform a repetitive task is now well understood however the “productization” of these cobots for functional change in the field is not mentioned.
I would be interested in any practical information, articles or technical reports regarding these myriad issues.

“An unstructured project is frustrating and confusing for the team and it is the responsibility of the project manager to ensure such structure is in place to facilitate team activities and discussions.”
Elisa Cepale

Just because there are deadlines for “deliverable articles” does not mean that the project is structured. It must have a defined life cycle which is monitored and followed no matter what life cycle is defined with preferably co-located collaborative meetings in addition to transparent, real time software for collaboration with stakeholders and SME’s.
