It's a B-U4D.  According to the documentation it's a "loading droid, class 5".   I think it suffers from the same poor, barely articulated, lacking in visual interest, design sensibility as all the droids from The Force Awakens unfortunately, which is why it had't been included here earlier.  But here he is now, in all his boxy glory
