Power Supply Question

Hello, and thanks for reading my question!

I am following the robot shop Arduino introduction to robots tutorial and have added quite a few items to my cart and was just about to purchase them before I realized I had no power supply in my cart.

I am very new to building robots (My first time)

and I have no idea what I need to power my first robot, the tutorial confused me quite a bit with the power supply portion, I am a programmer by career but when it comes to electrical components I have a lot of learning to do!

I am not sure if I need multiple power supplies or even what voltage(s) I need for my power supply or power supplies!

Any help or pointing in the right direction would be much appreciated! Ill put a list of products I have in my cart in case that helps! Thank you for reading!

DFRobot Arduino Compatible Motor Shield (1A)
Code: RB-Dfr-04

GM9 - Gear Motor 9 - 90 Degree Shaft
Code: RB-Sbo-07

Arduino Uno USB Microcontroller Rev 3
Code: RB-Ard-34

And I don’t think these affect what supply I need but I’ll list anyways!

170 Tie Point Mini Solderless Breadboard Pair - White
Code: RB-Cix-05

BasicATOM Standard GM Track Kit (w/ Axles)
Code: RB-Bat-29

Once again, thank you so much for reading! And any help would be appreciated!

Essentially you’re creating the RobotShop Rover. This robot uses one 9V battery pack for the Arduino microcontroller (which ideally works best at 7-12V) and a separate one for the motors (6V is best). You can use a 4xAA pack to get 4.8V to 6V (depending on which batteries you choose) or a rechargeable NiMh packand charger (just ensure you have the mating connector for your robot). If you really want to avoid using two batteries, you’ll need a voltage regulator (step up from 6V to ~9V).

First off, thanks for your reply!

I will be purchasing those items today and getting started on my first robot asap!
