Otto Punk robot

I was in search for a cool project to do with Arduino Microcontroller and I came across this little robot Otto+ . Although there is detailed information on how to build one in the above link I found it quite confusing with the variety of the files versions and decided to bring here a clear version that works for me with some modification New head to fit better the sound sensor, Ultrasonic sensor, Arduino nano+Shield with holes to Voltage and mini USB New Body with customize space for on/off switch, USB charger,18650 Li-Ion battery and LED matrix I was in search for a cool project to do with Arduino Microcontroller and I came across this little robot Otto+ .
