Great job so far. What are you going to use for the grabber / picker? Also, how do you propose to feed the parts?
It looks like this platform has many possibilities. Change the pin for a laser?
Great job. Cant wait to see the finished product in action.

Hi - thanks, that's an interesting idea to change the pen to a laser pointer until our real head is mounted.
I'm going to make another post shortly that covers more of the mechanicals. Ed's head has the Z-axis and also rotation (theta). A tube can be connected at the top going to a vacuum pump. The valve will be controlled by a solenoid that can be switched on and off from a transistor connected to the TinyG (certain G-Code will then actuate it when needed). If that doesn't work, then we can interface to transistor to an output pin on the BBB. When necessary, the Python program and toggle the BBB pin in between writing G-Code commands to the serial port (which goes to the TinyG).
For the feeder, we have a piece a delrin (which is like a hard plastic) which another member had machined with 8mm slots in it (I think there are 10). Cut tape with surface mount components will fit in the slots. The slots are about 6" long and an acrylic covering would go over the top to hold the tapes in the slots. One side of the slots wouldn't be covered so the PnP head pick the components out of the containers in the tape.
Hopefully some photos and video in my posts will make it clearer.
Did I describe those design goals correctly?
Thanks,
