How it was built?

Hello, all.

I found on youtube such amazing videos



How to do such things, they are amazing!!!

Unforutunatly in that topic only basic problems of motion.
I'm interested how to make such thing as on second video, with camera and point motion. And how to connect openCV to linuxcnc.

The camview widget in Qtvcp uses opencv.

linuxcnc.org/docs/2.8/html/gui/qtvcp_wid...ml#_camview_widget_2

That is really amazing.

I wonder, this machine pick and place electric components.
How they fix at their places on PCB? Does it's used some glue?

I tried to solder such small components (resistors, capasitors) but they stick to solderer or moves with some magnetism or static, it was very difficult.

Typically the parts are just held by gravity + the stickyness of the solder paste.
Parts on the reverse side of the board are often glued on to allow wave soldering.

i think i posted the link here somewhere to the github where i put the whole thing: github.com/yur7aev/linuxpnp if you want to know how exactly it was done...

the second one (mouse dragging the camera image) is really straightforward:

github.com/yur7aev/linuxpnp/blob/master/configs/pnp/vision.py exports 4 HAL pinswhich are updated onand are connected toand that's basically it. it was a proof on concept after i played with OpenPNP's somewhat non-conventional way of dragging the camera...

Thanks a lot Dmitry, for explanation. I hope, I will try somethink with using your ideas.

Dm17ry, You have solved very important and difficult task with this project.
