Vibrobots have a good thing and a bad thing. The good thing: You can build a vibrobot even if you're bad in electronics and mechanics. The bad thing: If you only know to build vibrobots, soon you will get bored and frustrated of making always stuff with the same kind of motion.
Well, suppose you only know how to build vibrobots. So, what's the next step for not getting bored? Well, change the aesthetics and make bizarre things. Bizarre bloody things!!!
This is a vibrobot (as the shown in https://www.instructables.com/id/Build-vibroinsects-using-discarded-mice-Go-Team-M/) with a LED lighting its eye. The main material are broken joysticks. The lower body is the main part of a broken generic joystick, and the legs and arms are made of the handlers.
The upper body and blades come from a printer, and the head was made from a roll-on deodorant ball, a LED and an "Action Man" action figure helmet. The eccentric weight is the bottom of a blender glass. And the Barbie? Well, she was a poor Barbie found in a Flea Market.
You can see the video of this abomination working.
Too gory for you? Well, you can make a bigger joystick vibrobot, like the A.N.T. (Armored Nerd Technology). It was made with Genius joysticks (and no Barbie). This time, the eccentric weight is the gaitling gun.
But I love the Barbie-killer one. It's very "Quake 4" style!!!! :-)
