This is a machine for placing SMT components on PCBs. It is based on Acro system, off the shelf parts, and a number of custom 3D printed elements.

The COTSPnP pick-and-place machine (PnP) is used to place surface-mount devices (SMDs) onto a printed circuit board and was designed and built exclusively from off-the-shelf (COTS) components, predominantly sourced from OpenBuilds and Actobotics. Its intended use is prototyping and not high rate, high volume production and is capable of precisely placing parts as small as 0402 capacitors and resistors but more importantly, can precisely place components with lead spacing as small a 0.4mm.
