How to make a LEGO rolling robot
PALLA is a LEGO Power Functions remote controlled contraption with amazing obstacle-disentangling capabilities. “PALLA” is the Italian word for “ball”, and it’s an acronym that stands for Pet-Annoying Loud Likely-Awesome contraption. I call it a rolling robot, but it’s just a remote controlled contraption . Having just one motor, its behavior is quite random, so driving it requires a little practice. It’s incredibly funny, and despite its name, it’s pet friendly. Check the video!

I reworked my original LEGO rolling robot to make it roll smoother and fully controllable. I redesigned the core of the robot so that now you can steer it precisely using two LEGO Power Functions Motors. Click the button below to download the building instructions.
