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 electronics 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
