Note: this is not a nonsensical group of things I just threw together. My friend, who goes by the name of Quirkro, founded Obscuro Robotics as a lego robot design group. I am the head designer for the Z division, which puts emphasis on brute force and firepower, while he is the designer for the Y division, which focuses more on agility.
Step 1: Z-step Core
Step 2: Z-1
Step 3: Z-2
Step 4: Z-3
And those, for now, are all the head designer of the Z division of OR can present to you. I encourage you to make your own, as this is a very versatile robot designing system. Hope u njoyed!
