Well, yes, but I think you're all missing the point. When the spot changes color, any worker WHO IS READY can press the button. You're all slaving a mechanical finger to the spot; regardless of whether the operator is ready or not.

One part that got left out is, how often are these jobs presented? I've never worked on a piece work basis, but my impression is that they would be presented very fast. Fast enough that no operator could be ready every time for all them.

Another question is what else are these tablets used for? Since the operator apparently is not waiting for physical stuff to be delivered to the work station (as in sewing clothing together), is the work also done on the tablet? If so, that limits the hardware you can have hovering over the screen.

And of course, when all the operators have these goodies, then you are right back where you are now, taking pot luck.

Also, there are better web sites than this one for this kind of project. "element14.com"comes to mind. Search for "maker movement" for more contacts.

A suggestion that I would have to actuate the button, at least if you are using a servo, would be to use a cam linkage to depress the button on the screen. If you set it to move to an angle past the actuation point when a color change is detected, it will "tap" the screen.

It's like the side of a train, sort of, in how it works- I hope the picture I've attached helps.



The output shaft is at the top of the image, and the spring holds the output shaft against the cam, so that it follows any grooves/ depressions/ rises in the cam surface; for example, rotating this cam counter- clockwise would cause the shaft to actuate, and then pull back, beginning to actuate again as it nears the elongated end of the cam when it has gone a full revolution.

Well the OP did say that he wanted a device to hit the button as fast as possible. He didn't say anything about not being ready...

And if he wasn't ready, well maybe he can build in a switch that disables the mechanism.
