Help Designing

I want to create a very simple robot and have been researching PCB setups and how to solder. However I’m still pretty confused and am wondering what products are worth their price. I want to have a motor, power source, motion detector, and a switch for the direction of the motor. Is there a simple way to accomplish this?

I’m not very experienced in electrical engineering, any advice is great!

Being new, I’d suggest buying the ready made boards & kits available for the arduino etc.
