When experimenting in building bobble head kissing dolls I came up with the idea of giving them a geeky twist.
Check out the video:
These robots are made with love and out of love …and the materials described below. They make a great Valentine gift to your true love or you can offer them to anyone deserving your robot love. You can however not sell them: love, even robot love is not for sale ;-)
I usually offer these as kits to be assembled by the recipient, as I love makers and I tend to encourage my “loved ones” into making. I prepare up until step 7 and refer to step 8 to 11 for the assembling. This way I bring Instructables to their attention (but of course my “loved ones” have heard of Instructables from me more than once). Making two complementary kits also allows offering a love robot to each individual in a couple.
The robots swing on an internal pivot point, with their weight distribution making them lean backwards, but only just. The attraction force of the magnets in their mouths overcomes this unbalance, making them lean forward on approach and kiss. Keeping all moving parts light helps to keep the movement back and forth smooth. Hence the idea of using ping-pong balls.
When using laser cutting it was easy to make the arms also serve as assembly tools (keys to M3 hex nuts), so no tools outside the kit are needed for assembly. I know that with laser cutting it is very feasible to make an assembly kit that doesn’t require any tools, but after a couple attempts to make a 2D cut pivot point I decided it was best to use a bolt for the main pivot axle. Furthermore, using bolts to keep the parts together also means the measurements are less critical and keeps open the option to contour saw the parts by hand.
The tittle is a tribute to the great Ible "Give the gift of Robot Invasion".
