This awesome video was edited by Johannes Rauer, who you can find on thingiverse.com/JRauer.
You can find all the resources for this project on thingiverse www.thingiverse.com/thing:3967555. We created a very detailed construction manual, which shows every step of the printing and putting together process. Note that you can print the basic robot without the pick-and-place stuff surrounding it.
