No motive power was demonstrated yet, the presented molecule is not able to move anythings. A bit of history here:
-1998 (from IBM Zurich and CNRS Toulouse): the first observation of a single molecule rotor (Science, 1998)
-2007 (from Berlin Frei University and CNRS Toulouse): the first assembled molecule rack and pinion (Nature Mat., 2007)
-2009 (from IMRE Singapore and CNRS Toulouse): observation of the step by step rotation of a single molecule gear (1.3 nm) mounted on an atomic axle (Nature Mat., 2009)
-2011 (from Tufts University) the Sykes electrical “motor” (Nature Nano, 2011)
-2011 (from IMRE Singapore and CNRS Toulouse) the smallest ever nanofabricated solid state gear: 60 nm (Nanotechnology, 2011)

For the actual 2011 Sykes “motor”, it is a very nice piece of work but it is not a motor.
it is an electrical rotor whose mechanics is depending on the surface. No motive power
was demonstrated yet, the presented molecule is not able to move anythings.

Once you have motors that can be stopped and started under human control, the next step is to add shafts and gears and other mechanical systems that can be used to produce useful power and mechanical/kinetic force, which leads ultimately to devices able to assemble materials with atomic precision.

Also, seems there was some Singapore group that made some programmable nano-motor recently. It will be interesting to see how quickly they graduate to more gears and then other mechanical systems.
