My first attempt to build and run a quadruped. Parts of laser cut acrylic. Powered with an arduino uno and sensorshield. Total of 12 micro- servo's, partially metal geared. It proved very difficult to align the servo's right. It walked, it turned. But was abandoned after I blew up most of the servo's by feeding them 7,4 Volts instead of 5 :P Anyway, it's pretty much a copy of this one: https://www.robotshop.com/letsmakerobots/node/34412 I had to use 3mm acrylic, because the lasercut firm had no 4 ...

I had to use 3mm acrylic, because the lasercut firm had no 4 mm available.

Initially run it on a heavy 7,4 V lipo (5000mAh) through a wire because I didnt have a light enough lipo at hand. The voltage regulator ran very hot in the first place.

And yes, I nearly have all the parts at hand to build it again, and will in the near future.

If there are any specific questions, I'll try to answer them, of course.
