Another website with LEGO GBC information and links.
Getting Started You’ll need power function motors and a power supply. The can be purchased from https://shop.lego.com. I’d recommend starting by copying someone else’s design; several modules are listed below.
And you’ll need LEGO soccer balls, which are about $1 a piece.
