A good many women are not even remotely interested in electronics or robotics. Pretty women typically aren't interested in deeply technical topics. You take them for a nice stroll at the zoo, mini-golf, amusement park, or a nice scenic boat ride. Boat rides, especially the ones that serve a nice dinner aboard are very nice.
If you have your own nice boat, you can take her far out just beyond sight of land and then say to her,
"put out or get out!!"
After landing the boat ashore, be expecting to be picked up by the police!!
