How should I start doing simple and small robotics projects? What motors to buy? What about wheels?
I need to find motors that are inexpensive and be able to re-use them in many projects. I don't need servos or stepper motors. At least not yet :) So I don't have a specific project up but I want to have a few motors around to make stuff.
I'm confused because I don't know where to start: Should I choose the wheels first and then find the motor or the other way around? :) Where do you suggest I shop from (online)?
How should I fit the motor onto a chasis?
