9g micro servo hexapod

thingiverse

So I had some spare cheap servos and an Arduino just sitting around waiting to be used, and I decided to build a really cool, totally affordable hexapod. The parts were all super easy to print and fit perfectly with TowerPro SG90 or SG92 micro servos. I took inspiration from fungy's awesome hexapod over on Thingiverse at https://www.thingiverse.com/thing:56698 - his design is so good, I even borrowed it a bit. The idea for precisely controlling all 18 servos with an Arduino came from Lamja at http://www.lamja.com/?p=504, and I took Arvid's code and modified it to work like a charm on my Arduino Leonardo with its Atmega32u4 chip. And here's the best part: you can get 20 of those cheap servos for just $30 from Aliexpress - no joke! An Arduino Nano will run you about $4, and a little step-down converter for a battery will cost only a few bucks, plus an ESP8266 wifi module for your Arduino is just a few more bucks on top. All told, it's going to be way under $50, excluding the price of the battery. I even added some nice top and bottom plates that are basically just scaled versions of fungy's design - but don't worry, I'll be making some new ones that fit my battery, Arduino, and all the rest perfectly.
