Mechanize (8)
I believe the answer is:
automate
'mechanize' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for automate that I've seen before include "Convert to robotic operation" , "Make (a device) work with little human control" , "Eat out ma - make it self-regulating" , "Mechanise to make something work without human intervention" , "Cause to function without direct human control" .)
