BoB a fun introduction to the world of walking robots for children and adults alike! with simple construction and very low part count you can have your bob up and walking in no time. i've updated recently to include the BoB poser software by robotfreak modified from the fobo poser software just load the arduino code onto the controller and plug in BoB to usb and get posing! it allows a frame by frame sort of capture mode and playback making animations easy

you need:

printed parts

 1 X head  

 1 X base  

 2 X bracket  

 2 X feet  

electronics

4 X 9g servos  

micro controller of choice (ardiuno nano fits nice)   

battery (nimh 9v, lipo, AAAs, whatever you have that works)  

sr04 or ping  

3mm leds  

a little tip. for faster printing feet in cura you can "sink" the print down 2.5mm it takes about 10 minutes off the print time
