I installed Infernal Robotics - Next and everything works on KSP 1.4.1, 64bits. It's still beta but so far had no problem. I added Utlitrons (landing foot, grabbers, sampler) from older versions of Rework.
To control it's moving parts you need to find and press IR's toolbar button which brings the servo control window, or use actions.
But I couldn't get the Sequencer from the same page to work and it doesn't appear in the toolbars and couldn't find any help in this regard (tested both releases for 1.4.1 and 1.4.2)..
