I am new to this whole Robot making thing but I Fix and Make Computers so I say what the hell.
But I am going to make my Robot from the Ground up and step by step so I just have a Q/A for now.
If buy wheles and a Moter how do I get them to go onto a Frame? What I meen is say I know the Wheles I want and I get a Moter it has to go good with a Frame it can't just PLOP on a Frame the Whelea have to hit the ground.
So I will tell you what I am making and maybe someone can help.
I want my Robot to have TANK Wheles you know the kind with the Robber Belt that goes over them. I think this will be good for indoor and outdoor use.
But how do I find a good Frame to have the Wheles go next to and ware do I get it??

A couple of pointers:
1. Don't use a DC motor for your first robot, start with a continuous servo (modify acc. to tutorials here or buy ready). Why? Because you can't just connect a DC-motor to your circuit anyway you please, this will in worst case kill your microcontroller as DC motors generate lots of severe electronic disturbance. To connect a motor you need a motor controller, like an H-bridge. Servos are much easier and works great for alot of cases probably including yours.
2. Your frame is depending on the wheels dimensions, the length between the weels and so on. Either you choose a frame and then try to find wheels etc to go with that frame, otherwise find the wheels first and then try to create or find a frame to go with that setup.
3. Keep it simple. Ok, so your friends won't be too impressed with your three month robot project with a bot avoiding obstacles, but that is because they lack the knowledge of robotics. If you are building it from scratch as it seems, it won't be plug n play...

Maybe you're better off buying a kit with treads (that's the name for tank like wheels).
Or read and research alot about hobby robotics, because all of your questions can easily be answerred if you'd research more...

whats your budget for this project?
once we know that we will know what to suggest for you
