>> Hey, do you have pictures anywhere? Not yet, but I really doubt the pictures would say much.
I have a Mamiya Superhand single head unit. It uses mechanical jaws for part centering (no machine vision) and the head is only able to rotate 90 degrees. I used the existing stepper motor drives, because the motors are 5 phase, giving you 500 steps per revolution. The motors will run faster than my PC will put out and this is fine for now, because speed is really not an issue for me on this machine. The two axii each have two optical limits and an optical home. The machine also has a 4 head nozzle changer and a conveyor belt. All of the pneumatic solenoids are now sunk through ULN2803 arrays wired directly to the parallel ports through the breakout boards. I wrote the g-code generator in php. I still have a little tweaking to do on it, especially with the pause delays, but it works in concept. You can see the output here: http://www.probotix.com/pick_n_place.php I promised the robot club some videos. I'll post a link here too when I have it. I actually have two more Mamiya three head units that came in the lot. I do not have need nor room for them, so I will eventually be parting them out or selling to someone who lives close enough to pick them up. >Len ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
