Regarding OpenCV I have looking until now for some answers. I have found an interesting and probably adaptable example : http://www.codeproject.com/KB/cpp/TrackEye.aspx?fid=1403145&fr=101&df=90&mpp=25&noise=3&sort=Position&view=Quick#xx0xx Also it's an interesting thread on cnczone about making of pnp machine. I’m intrested too.

If the bottom of your tray is slopped 45 degrees then the components will stack on one of their sides by themselves. If the component goes automatic at the place of picking then all it is necessary is pick them and rotate or not. Sorry for the bad English :-) Hello,

The RepRap pick and place head is what originally got me started on this idea and it seems like the forum has a lot of good info. I will participate there. Thanks! Thanks for your comment.

A forum discussing a similar idea as a tool head for the 3D open source printer, RepRap. Might be useful for some ideas.

I see this system serving both CNC mill and Open PnP. http://www.youtube.com/watch?v=vPPhwoe2QMU&NR=1 Forgot to add another alternative to the ServoBelt drive system called the “Roller Pinion”…this could also be “DIY” duplicated with a little time and effort.

I found something that could be duplicated fairly easily with the right tools called a ServoBelt drive on YouTube. http://www.youtube.com/watch?v=OdJoVh6DRPA Take note that NEMA 23's were used in some of the demo units shown in the video.

Another software package that I have come across by accident via Ubuntu 9.10 Server package installer is called Harpia (offspring of OpenCV). The nice thing about Harpia, it uses a flow chart style GUI for piecing together a vision system. Unfortunately I have only been playing with this application for the past couple days so trying to learn how to export the data for practical use in a PnP enviroment. It does appear to have the ability to export data from some of the module and supposedly aids in generating code based on your flow. (Again only been playing with it for a few hours!)
