Theres so many and I don’t know how I would quite use them. How they fit together. Is there a guide somewhere?
there is no easy answer to this beyond the obvious buy a few and try it. you can study the different pictures in the tutorial assemblies or d/l the cad models and put stuff together virtually. aside from the assurance that stuff lines up when you mix and match brackets and servos there is no way to explain the process. perhaps one of the smaller budget hexapods or a brat jr would be a good investment to get you head around how it all work together. other than the obvious value of a starter purchase like that is the fact the same brackets can be used again in the next higher level assembly. I’ve made a 3dof hex, brat, scout, tracked inspection rov, and 5-axis arm and the parts just move from one assembly to another as my interest wanders and free time comes and goes. just pick something small but interesting to get your hands dirty and you will grasp the concepts quick enough.
There is also a vast array of assembly guides for our robot kits. Most use a bracket or two. 
We’re quite proud of our assembly guides and recommend people look them over for ideas.

There are also a lot of assembly guides in the Servo Erector Set section of the website.

The Servo Erector Set currently includes over 143 unique components. It can be intimidating, but it’s just robots…
wow thanks a lot. I was in the middle of typing up a huge response, but I think these assembly guides will give me something to look over and will most likely answer my questions.
The BRAT Jr. Or the bigger brother BRAT are both fantastic starter bots. Like Eddie said, the brackets are interchangeable and can be applied to more complex bots later on down the road.
For example, you can start with a BRAT Jr. and progress to a BRATINATOR like I have built, or make a new style BRAT beyond what’s already been done. All the brackets are reusable and you can even sell or trade them on these forums with other members. The SES brackets is a robot hobbyists dream come true.
