Building a pick and place with 3D printed parts



For the last few months, [HeliumFrog] has been building a SCARA bot to serve as the basis for a pick and place machine. Somewhat amazingly, this is the first robot of its kind to be printed on a 3D printer.

A SCARA-type robot is an articulated arm perfectly suited for transferring components from tubes and reels to a PCB. [HeliumFrog] began his build with an arm with large gears in joints driven by stepper motors and toothed belts. The Z axis was originally driven with a lead screw, but after a thoughtful redesign that was changed over to another toothed belt.

We’ve seen our share of DIY pick and place machines, but most of those have been based on a traditional X/Y Cartesian frame. [HeliumFrog]‘s SCARA bot should be – theoretically, at least – faster and more accurate while taking up a smaller footprint in the workshop.

[HeliumFrog] is more or less done with the basics of his build, and is now moving on to building a plastic extrusion tool head for his SCARA bot. Very cool, and should make this robot capable of self-reproduction for under ?400 (~$600).

You can check out a video of this articulated arm bot after the break.

Thanks, [Kyle] for sending this one in.
