Otto Ninja Demo (Nano v3 & 16340 battery)
Remixed to support: 16340 Battery, Nano V3 plus Shield. Used an 8x16 Matrix LED, buzzer, switch. A second O-Ring was added to the bottom of each foot for grip on smooth surface. This makes the Ninja a bit more consistent when walking (as consistent as open loop systems can be). All construction and ordering details at Printables:
