About Us:

Douloi Automation Inc. is a privately held corporation founded in 1991 by J. Randolph Andrews (B.S.M.E., B.S.E.E., M.S.E.E, MIT). The company was created to provide real-time motion control solutions for use with the then emerging Microsoft Windows technology platform. Windows did not demonstrate, nor was designed to provide, the real-time behavior necessary for motion and machine control. Douloi Automation utilizes its RTOS (Real Time Operating System) hardware and software tools to augment Windows with the necessary real-time capabilities required to control machine and motion behavior.

The term "Douloi" literally means servant. The concept is that Douloi Automation products are servant to both machine control and customer desires.


Douloi Automation will provide hardware and software tools to enable clients to rapidly describe machine behavior and produce advanced motion control solutions quickly. Douloi is committed to mutually beneficial relationships with its clients where integrity, effectiveness, and timeliness are of paramount importance.
