Hold off on CAD until you're ready for more complex designs. For right now, I suggest using what I call the black box method, which is designing a bot with a whole bunch of imaginary boxes. Then after the layout has been made, you design the components to fit within the allowed space. This method would help you in the future when CAD is ready.
I meant asking local teams. They are always willing to help.
Also maybe your team should not be focused on winning, but instead focused on teaching English and teamwork through robotics. .02$
