#Anamatronic zombie drop update

If you are using RC batteries, you could use a UBEC from the radio control world (HobbyKing has quite the selection, I have read good things about the TURNIGY 8-15A UBEC for robots, but have never tried it myself) I used an obsolete Volgen FDC15-48S05 which I got out of a scrapped piece of telecoms equipment, so you are unlikely to find one exactly the same. What you need here is dependant on your batteries, read electronics section for more details). You can use whatever is available to you, your choice will affect your DC-DC converter requirements.ĭC-DC converter/UBEC (Universal Battery Elimination Circuit)

I used 6x 4.2V Li-ion batteries that I got for free (they expired 10 years ago, but heck, this is a zombie right?).

Use any micro controller that you like, but I am partial to the Arduino Nano, which I buy by the boatload from DealExtreme. I used Corona DS-239MG from HobbyKing, since I had them on hand. I imagine 9g servos would not be up to the task though. The servos for the neck (if you choose to animate it) don't have to lift much weight, so small low-profile servos will do. The ball bearings turned out to be a fiction though, the shafts are supported by brass bushings. I used TrackStar TS-600MG from HobbyKing since I liked the sound of metal gears and dual ball bearings. These have a bearing on either end of the output shaft in order to better handle side loads. I would also recommend going for dual-bearing servos if possible. The servos for the arms need to be relatively high torque since they have to lift the weight of the robot.

Update 2: Added Remote Control (step 21) and a more in-depth video So I won a prize in the Halloween contest, thanks for your votes! I started this whole project for an Instructables contest, so if you think it's cool, and you don't want to risk being eaten by spurned zombots, I'd appreciate your vote!

I guess this could happen to you too, don't worry though, I got over it -) This project could be a pretty good introductory robot for someone who has never built one before.Ī word of warning: There was a point in the middle of this project when I was struggling to fit an undead robot into a dress and had to take a step back to ask myself what the heck I was doing with my time. In the same vein, my design has been planned around limited tools, you could make it with anything from hand-tools to CNC cutters or anything in between. Besides, you are a maker, you'll figure it out. I like to use whatever I can scrounge up for my projects, since it keeps the cost down, but it does mean that maybe you won't have exactly the same items on hand, I will try and give alternatives. My goal with this Instructable is to take a doll and (re)animate it with servos and mechanical linkages, its braaaaiiins will be an Arduino microcontroller. Lets help things along by building a creepy little robot zombie. We all love zombies and robots, two of the things that are most likely to be our undoing one day.
