Hardware Advice for project using motorized wheels with a quadrature encoder for beginner
hello all, I am very new to Arduino programming and hope to get some advice specifically for a power source requirement. this is a long one so sorry in advanced:
the goal of this project is to move a 50kg stander that has wheels by using a motorized wheel kit from parallax (https://www.parallax.com/product/motor-mount-wheel-kit-aluminum/) that has a quadrature encoder. each wheel has 12 VDC, 96 W, and requires 2.5 – 8.0+ amps depending on terrain and load.
we also want to implement 2 line sensors that the 50kg stander will follow, speakers that will play music, and incorporate a way to plug in an existing head-switch (https://enablingdevices.com/product/head-switch/?srsltid=AfmBOorFtaefJwLmKLel3S1I1kEQgzGLLbicd9KswG2DDRLfWUzKB5-W) that will allow controlled movement of the client on stander.
I know we need an arduino nano, we need two motor drivers for each wheel (or one that can take in the 2 motors), jump wires, fuses, amplifier for the speaker, 2 line sensors, but i'm confused about the power source. what voltage should we be looking at for a power source for this type of stuff? (could you also check if what i listed is accurate?)
to be clear: the motorized wheels are not carrying the stander, but merely pulling it. the wheels are moving on indoor hardwood floor. we are planning for the lines to be thick and black.
thank you!

Your needing to do a power audit sheet.
So like an excellent sheet you populate all the categories. Motor stall current. Amp power. How long you want it to run for battery or not battery powered. Ect ect. You will go throughout all the data sheets for all componunts and get the data. Populate the sheet. Then share the sheet and we can help from there if useinng a cloud drive just make a folder and you can save all data sheets in the folder with the audit page.
