Asi (Anansi) Wearable Robot

This project was originally going to be an Xpider, from Thingiverse. Then I say Archimedes by Alex Glow. It blew my mind. I wanted one so bad. So, I got to work on own robotic companion. I figured I am not a owl type, and I wanted my familiar to be special. Then I remembered the African story of Anansi the spider, trickster and god of stories. I decided to design the bot with the idea of a story, and thus Asi was born (it's actually Asi_v4, v1-3 were prototypes).

You're Goint to Need a 3D printer, Arduino Nano, Adafruit Trinket 5v.

Assembly is pretty self-explanatory but here are some pics anyway.

For the electronics, you can usually put them in the top or the bottom of the head (your call), but the servo has to be attached as so. Make sure the gear is on it, please.

Asi is controlled by two microcontrollers, a Trinket and an Arduino Nano. The Trinket controls the movement of the eye, thanks to the servo it turns back and forth at random intervals. The Arduino Nano controls the eye. It's also random as he looks around and such, usually people assume he is looking at them.

Note, I have them on two small breadboards that are daisy chained with 4x AA batteries. (You can also use a lithium-ion battery 3.7 200mAh. With the li-on battery, I have had times for some reason where it would not work, so I would use two separate lithium batteries and attach them to the same on off switch so everything starts at once.)

The head is just a Christmas sphere I got during the holidays. I took a step back and sprayed it lightly with black spray paint. Then take some hot glue and glue it to the neck piece of Asi and BOOM there is the head!

Lastly, how I wear it. I just took some armature wire and strung it through the wholes on the bottom part of Asi, and wrapped them on my shoulder pack of my backpack.
